Background Context
Lumbar spinal stenosis (LSS) can hinder a patient's physical activity, which in turn can impair glucose tolerance and body weight regulation in patients with type 2 diabetes mellitus (DM-2). Therefore, successful lumbar surgery could facilitate glycemic control and body weight regulation.Purpose
This study aimed to evaluate the effects of postoperative improvement in physical activity on body mass index (BMI) and hemoglobin A1c (HbA1c) level in patients with LSS and DM-2 over a 2-year follow-up period.Study Design
Prospective longitudinal observational study.Patient Sample
Patients with LSS and DM-2.Outcome Measures
Visual analogue scale (VAS) scores for back pain and leg pain, Oswestry Disability Index (ODI) scores, Japanese Orthopaedic Association (JOA) scores, JOA Back Pain Evaluation Questionnaire (JOABPEQ) sections, BMI, and blood analysis for HbA1c were carried out.Methods
A total of 119 patients were enrolled for analysis of the effect of successful decompression surgery on changes in HbA1c levels and BMI. The VAS score, ODI score, JOA score, JOABPEQ, BMI, HbA1c were reassessed at 6 months, 1 year, and 2 years after surgery. Additionally, correlations between changes in HbA1c and changes in the ODI, JOA, JOABPEQs, and BMI were analyzed.Results
The overall values of HbA1c before and at 6 months, 1 year, and 2 years after the surgery were 7.08±0.94%, 6.58±0.87%, 6.59±0.79%, and 6.59±0.79%, respectively (p-values; 6 months: .024; 1 year: .021; 2 years: .038). In the not well-controlled sugar (non-WCS) group (preoperative HbA1c>6.5%), the difference between pre- and postoperative HbA1c was highly statistically significant (p<.01). The overweight group (preoperative BMI≥25) showed statistically significant BMI reduction in the second year after surgery (p=.034). The postoperative HbA1c changes are strongly correlated with the improvements of ODI, JOA, and JOABPEQ after surgery.Conclusions
The present study demonstrates that in patients with DM-2 and LSS, successful lumbar surgery may facilitate glycemic control by enabling an increase in the patient's level of physical activity. Additionally, it could help reduce body weight in overweight (BMI>25) patients with DM-2 and LSS. 相似文献2.

Background Context
Revision posterior decompression and fusion surgery for patients with symptomatic adjacent segment degeneration (ASD) is associated with significant morbidity and is technically challenging. The use of a stand-alone lateral lumbar interbody fusion (LLIF) in patients with symptomatic ASD may prevent many of the complications associated with revision posterior surgery.Purpose
The objective of this study was to assess the clinical and radiographic outcomes of patients who underwent stand-alone LLIF for symptomatic ASD.Study Design
This is a retrospective case series.Patient Sample
We retrospectively reviewed patients with a prior posterior instrumented fusion who underwent a subsequent stand-alone LLIF for ASD by a single surgeon. All patients had at least 18 months of follow-up. Patients were diagnosed with symptomatic ASD if they had a previous lumbar fusion with the subsequent development of back pain, neurogenic claudication, or lower extremity radiculopathy in the setting of imaging, which demonstrated stenosis, spondylolisthesis, kyphosis, or scoliosis at the adjacent level.Outcome Measures
Patient-reported outcomes were obtained at preoperative and final follow-up visits using the Oswestry Disability Index [ODI], visual analog scale (VAS)—back, and VAS—leg. Radiographic parameters were measured, including segmental and overall lordoses, pelvic incidence-lumbar lordosis mismatch, coronal alignment, and intervertebral disc height.Methods
Clinical and radiographic outcomes were compared between preoperative and final follow-up using paired t tests.Results
Twenty-five patients met inclusion criteria. The mean age was 62.0±11.3 years. The average follow-up was 34.8±22.4 months. Fifteen (60%) underwent stand-alone LLIF surgery for radicular leg pain, 7 (28%) for symptoms of claudication, and 25 (100.0%) for severe back pain. Oswestry Disability Index scores significantly improved from preoperative values (46.6±16.4) to final follow-up (30.4±16.8, p=.002). Visual analog scale—back (preop 8.4±1.0, postop 3.2±1.9; p<.001), and VAS—leg (preop 3.6±3.4, postop 1.9±2.6; p<.001) scores significantly improved following surgery. Segmental and regional lordoses, as well as intervertebral disc height, significantly improved (p<.001) and remained stable (p=.004) by the surgery. Pelvic incidence-lumbar lordosis mismatch significantly improved at the first postoperative visit (p=.029) and was largely maintained at the most recent follow-up (p=.45). Six patients suffered from new-onset thigh weakness following LLIF surgery, but all showed complete resolution within 6 weeks. Three patients required subsequent additional surgeries, all of which were revised to include posterior instrumentation.Conclusions
Stand-alone LLIF is a safe and effective approach with low morbidity and acceptable complication rates for patients with symptomatic ASD following a previous lumbar fusion. 相似文献3.

Background Context
Conventional laminoplasty is useful for expanding a stenotic spinal canal. However, it has limited use for the decompression of accompanying neural foraminal stenosis. As such, an additional posterior foraminotomy could be simultaneously applied, although this procedure carries a risk of segmental kyphosis and instability.Purpose
The aim of this study was to elucidate the long-term surgical outcomes of additional posterior foraminotomy with laminoplasty (LF) for cervical spondylotic myelopathy (CSM) with radiculopathy.Study Design/Setting
A retrospective comparative study was carried out.Patient Sample
Ninety-eight consecutive patients who underwent laminoplasty for CSM with radiculopathy between January 2006 and December 2012 were screened for eligibility. This study included 66 patients, who were treated with a laminoplasty of two or more levels and followed up for more than 2 years after surgery.Outcome Measures
The Neck Disability Index (NDI), Japanese Orthopedic Association (JOA) scores, JOA recovery rates, and visual analog scale (VAS) were used to evaluate clinical outcomes. The C2–C7 sagittal vertical axis distance, cervical lordosis, range of motion (ROM), and angulation and vertebral slippage at the foraminotomy level were used to measure radiological outcomes using the whole spine anterioposterior or lateral and dynamic lateral radiographs.Methods
Sixty-six patients with CSM with radiculopathy involving two or more levels were consecutively treated with laminoplasty and followed up for more than 2 years after surgery. The first 26 patients underwent laminoplasty alone (LA group), whereas the next 40 patients underwent an additional posterior foraminotomy at stenotic neural foramens with radiating symptoms in addition to laminoplasty (LF group). In the LF group, the foraminotomy with less resection than 50% of facet joint to avoid segmental kyphosis and instability was performed at 78 segments (unilateral-to-bilateral ratio=57:21) and 99 sites. Clinical and radiographic data were assessed preoperatively and at 2-year follow-up and compared between the groups.Results
The NDI, JOA scores, JOA recovery rates, and VAS for neck and arm pain were improved significantly in both groups after surgery. The improvement in the VAS for arm pain was significantly greater in the LF group (from 5.55±2.52 to 1.85±2.39) than the LA group (from 5.48±2.42 to 3.40±2.68) (p<.001). Although cervical lordosis and ROM decreased postoperatively in both groups, there were no significant differences in the degree of reduction between the LF and LA groups. Although the postoperative focal angulation and slippage were slightly increased in the LF group, this was not to a significant degree. Furthermore, segmental kyphosis and instability were not observed in the LF group, regardless of whether the patient underwent a unilateral or bilateral foraminotomy.Conclusions
Additional posterior foraminotomy with laminoplasty is likely to improve arm pain more significantly than laminoplasty alone by decompressing nerve roots. Also, performing posterior foraminotomy via multiple levels or bilaterally did not significantly affect segmental malalignment and instability. Therefore, when a laminoplasty is performed for CSM with radiculopathy, an additional posterior foraminotomy could be an efficient and safe treatment that improves both myelopathy symptoms and radicular arm pain. 相似文献4.

Background Context
In Lenke 1C and 2C curves, the choice between selective thoracic fusion (STF) versus non-selective thoracic fusion as the optimal surgical treatment is controversial.Objective
This study aimed to assess the radiological and clinical outcome of patients with Lenke 1C and 2C curves treated with STF.Study Design
This is a retrospective study.Patient Sample
A total of 44 patients comprised the study sample.Methods
Forty-four patients with Lenke 1C and 2C curves with adolescent idiopathic scoliosis who underwent STF were reviewed. Radiological parameters and Scoliosis Research Society (SRS)-22r scores were assessed preoperatively, postoperatively, and on final follow-up. The incidence of coronal decompensation, lumbar decompensation, and adding-on phenomenon were reported.Results
Mean follow-up duration was 45.1±12.3 months and mean age was 17.0±5.1 years. The preoperative middle thoracic and thoracolumbar/lumbar (MT:TL/L) Cobb angle ratio was 1.4±0.3 and the MT:TL/L apical vertebra translation (AVT) ratio was 1.6±0.8. Final follow-up coronal balance was ?13.0±11.5?mm, main thoracic AVT was 6.9±11.8?mm, and lumbar AVT was ?20.4±13.8?mm (p<.05). Lumbar Cobb angle improved from 47.5°±7.8° to 24.9°±8.2° after operation and 23.3°±9.8° at final follow-up. The spontaneous lumbar curve correction rate was 50.9%. There were 9 patients (20.5%) who had coronal decompensation, 4 patients (9.1%) who had lumbar decompensation, and 11 patients (25.0%) who had adding-on phenomenon. We did not perform any revision surgery. The SRS-22r scores improved significantly in the overall scores, self-image, and mental health domain.Conclusions
Selective thoracic fusion led to improvement in the radiological and clinical outcome for patients with Lenke 1C and 2C. Although no patients required revision surgery, the rate of coronal decompensation, lumbar decompensation, and adding-on phenomenon are significant. 相似文献5.

Background Context
There is little information on the relationship between magnetic resonance imaging (MRI) T2-weighted high signal change (T2HSC) in the spinal cord and surgical outcome for cervical myelopathy. We therefore examined whether T2HSC regression at 1 year postoperatively reflected a 5-year prognosis after adjustment using propensity scores for potential confounding variables, which have been a disadvantage of earlier observational studies.Purpose
The objective of this study was to clarify the usefulness of MRI signal changes for the prediction of midterm surgical outcome in patients with cervical myelopathy.Study Design/Setting
This is a retrospective cohort study.Patient Sample
We recruited 137 patients with cervical myelopathy who had undergone surgery between 2007 and 2012 at a median age of 69 years (range: 39–87 years).Outcome Measures
The outcome measures were the recovery rates of the Japanese Orthopaedic Association (JOA) scores and the visual analog scale (VAS) scores for complaints at several body regions.Materials and Methods
The subjects were divided according to the spinal MRI results at 1 year post surgery into the MRI regression group (Reg+ group, 37 cases) with fading of T2HSC, or the non-regression group (Reg? group, 100 cases) with either no change or an enlargement of T2HSC. The recovery rates of JOA scores from 1 to 5 years postoperatively along with the 5-year postoperative VAS scores were compared between the groups using t test. Outcome scores were adjusted for age, sex, diagnosis, symptom duration, and preoperative JOA score by the inverse probability weighting method using propensity scores.Results
The mean recovery rates in the Reg? group were 35.1%, 34.6%, 27.6%, 28.0%, and 30.1% from 1 to 5 years post surgery, respectively, whereas those in the Reg+ group were 52.0%, 52.0%, 51.1%, 49.0%, and 50.1%, respectively. The recovery rates in the Reg+ group were significantly higher at all observation points. At 5 years postoperatively, the VAS score for pain or numbnessin the arms or hands of the patients in the Reg+ group (24.7?mm) was significantly milder than that of the patients in the Reg? group (42.2?mm).Conclusions
Spinal T2HSC improvement at 1 year postoperatively may predict a favorable recovery until up to 5 years after surgery. 相似文献6.

Background
The long-term results of heterotopic ossification (HO) following lumbar total disc replacement (TDR) and the corresponding clinical and radiological outcomes are unclear.Purpose
This study aimed to report the long-term results of HO following lumbar TDR and to analyze the clinical and radiological outcomes.Study Design/Setting
A retrospective case review was performed for the consecutive patients who underwent lumbar TDR.Patient Sample
The study included 48 patients (60 segments) who underwent lumbar TDR.Outcome Measures
The time and location of HO development, segmental range of motion (ROM) of index level, the visual analog scale (VAS), and the Oswestry Disability Index (ODI) were analyzed.Methods
Forty-eight patients (60 segments) were divided into HO and non-HO groups, and radiographs were used to measure the time and location of HO development. We compared segmental ROM between two groups using flexion-extension radiographs. Clinical outcomes were assessed using the VAS and the ODI. Furthermore, the segmental ROM, VAS, and ODI scores of each HO class were compared with those of the non-HO group.Results
The mean follow-up duration was 104.4 months. Heterotopic ossification was detected in 30 of 60 segments following lumbar TDR, and HO progression was noted in six segments. The mean segmental ROM was significantly lower in the HO group than in the non-HO group. The mean VAS and ODI scores were not significantly different between the two groups. Segmental ROM was significantly lower in the class III and IV of the HO group than in the non-HO group. The VAS and ODI scores were not significantly different among the different classes.Conclusions
We found that the incidence of HO is the highest within 12 months after lumbar TDR, and the incidence might increase 5 years after surgery. Furthermore, HO progressed over time. Segmental ROM was decreased in the HO groups; however, the limitation in motion might have little clinical influence. 相似文献7.

Background Context
Hybrid surgery (HS), consisting of cervical disc arthroplasty (CDA) at the mobile level, along with anterior cervical discectomy and fusion at the spondylotic level, could be a promising treatment for patients with multilevel cervical degenerative disc disease (DDD). An advantage of this technique is that it uses an optimal procedure according to the status of each level. However, information is lacking regarding the influence of the relative location of the replacement and the fusion segment in vivo.Purpose
We conducted the present study to investigate whether the location of the fusion affected the behavior of the disc replacement and adjacent segments in HS in vivo.Study Design
This is an observational study.Patient Sample
The numbers of patients in the arthroplasty-fusion (AF) and fusion-arthroplasty (FA) groups were 51 and 24, respectively.Outcome Measures
The Japanese Orthopedic Association (JOA), Neck Disability Index (NDI), and Visual Analog Scale (VAS) scores were evaluated. Global and segmental lordosis, the range of motion (ROM) of C2–C7, and the operated and adjacent segments were measured. Fusion rate and radiological changes at adjacent levels were observed.Methods
Between January 2010 and July 2016, 75 patients with cervical DDD at two contiguous levels undergoing a two-level HS were retrospectively reviewed. The patients were divided into AF and FA groups according to the locations of the disc replacement. Clinical outcomes were evaluated according to the JOA, NDI, and VAS scores. Radiological parameters, including global and segmental lordosis, the ROM of C2–C7, the operated and adjacent segments, and complications, were also evaluated.Results
Although the JOA, NDI, and VAS scores were improved in both the AF and the FA groups, no significant differences were found between the two groups at any follow-up point. Both groups maintained cervical lordosis, but no difference was found between the groups. Segmental lordosis at the fusion segment was significantly improved postoperatively (p<.001), whereas it was maintained at the arthroplasty segment. The ROM of C2–C7 was significantly decreased in both groups postoperatively (AF p=.001, FA p=.014), but no difference was found between the groups. The FA group exhibited a non-significant improvement in ROM at the arthroplasty segment. The ROM adjacent to the arthroplasty segment was increased, although not significantly, whereas the ROM adjacent to the fusion segment was significantly improved after surgery in both groups (p<.001). Fusion was achieved in all patients. No significant difference in complications was found between the groups.Conclusions
In HS, cephalic or caudal fusion segments to the arthroplasty segment did not affect the clinical outcomes and the behavior of CDA. However, the ROM of adjacent segments was affected by the location of the fusion segment; segments adjacent to fusion segments had greater ROMs than segments adjacent to arthroplasty segments. 相似文献8.

Background Context
Depression is associated with greater postoperative disability in patients with lumbar spinal stenosis (LSS). No previous studies have reported the association in a 10-year follow-up.Purpose
To evaluate the association between preoperative and postoperative depressive symptoms and the surgical outcome among patients with LSS in a 10-year follow-up. In addition, we examined the effects of the depressive burden on the surgical outcome.Design
A prospective observational follow-up study.Patient Sample
A total of 102 patients with LSS underwent decompressive surgery, and 72 of the original sample participated in the 10-year follow-up study.Outcome measures
Self-report measures: the Oswestry Disability Index (ODI) and visual analog scale (VAS).Methods
Data were collected using a questionnaire that was administered seven times during the study period. Depressive symptoms were measured with the Beck Depressive Inventory (BDI). The depressive burden was calculated by summing the preoperative and all follow-up BDI scores. Statistical analysis included cross-sectional group comparisons and linear mixed models. The authors report no conflicts of interest related to this work.Results
The high depressive burden group had a poorer outcome for pain, disability, and the walking distance at the 10-year follow-up. In linear mixed models, a higher preoperative BDI score associated with higher disability. Furthermore, higher postoperative BDI scores and the depressive burden were associated with higher disability and pain in the 10-year follow-up.Conclusions
Patients with LSS with even slightly elevated depressive symptoms have an increased risk of postoperative pain and disability in a 10-year follow-up. To improve the surgical outcome among these patients, screening for depression both preoperatively and during the rehabilitation following surgery is important. 相似文献9.

Background Context
Several osteotomy techniques including pedicle subtraction osteotomy and vertebral column resection have been employed in the correction of congenital kyphosis (CK) and satisfying outcomes have been demonstrated. However, the Scoliosis Research Society (SRS)-Schwab Grade 4 osteotomy, defined as resection of posterior elements, partial vertebral body, and superior adjacent disc, is rarely reported in the treatment of CK.Purpose
The present study aimed to evaluate the efficiency and safety of SRS-Schwab Grade 4 osteotomy in patients with CK, and to propose its optimal indication.Study Design
This is a retrospective analysis of clinical and radiographic outcomes of patients with CK undergoing SRS-Schwab Grade 4 osteotomy.Patients Sample
Patients with thoracolumbar CK undergoing SRS-Schwab Grade 4 osteotomy from January 2010 to May 2015 followed up for at least 2 years were retrospectively reviewed.Outcome Measures
The thoracic kyphosis, lumbar lordosis, segmental kyphosis (SK), sagittal vertical axis (SVA), pelvic incidence, pelvic tilt, and sacral slope were measured on lateral spinal x-rays. Patients were required to fulfill the SRS-22 questionnaire at preoperation and the last follow-up.Materials and Methods
The sagittal spinal-pelvic parameters were assessed at preoperation, postoperation, and last follow-up. The comparison between preoperation and postoperation was performed by paired samples t test.Results
A total of 38 patients with CK (17 male and 21 female) with an average age of 16.5±9.9 years were included. The mean operating time was 242.7±88.1 minutes and blood loss was 634.5±177.8?mL. The mean follow-up was 38.8±20.3 months. The SK was 49.5±11.7° at preoperation, 6.8±7.4° at postoperation (p<.001), and 8.0±8.1° at the last follow-up. No significant correction loss during follow-up was found in SK (p=.125). The SVA was improved from ?36.0±18.3?mm at preoperation to 3.7±17.8?mm at postoperation (p<.001), and the correction was well maintained during follow-up (p=.113). Compared with preoperation, the mean postoperative scores of each domains of SRS-22 questionnaire improved at different levels. Intraoperative complications included one case with incidental dural tear and another with transient root injury. Proximal junctional kyphosis occurred in three patients at 6 months after operation and remained stable during the follow-up. At the last follow-up, all patients were identified to have achieved solid bony fusion.Conclusions
The SRS-Schwab Grade 4 osteotomy, if selected appropriately, could provide satisfying correction of congenital kyphosis. The correction could be well maintained during the longitudinal follow-up. 相似文献10.

Background Context
Controversy exists regarding percutaneous balloon kyphoplasty (PBK) in patients with a very severe osteoporotic vertebral compression fracture (vsOVCF).Purpose
The study was conducted to investigate the clinical and radiological outcomes of PBK for the treatment of vsOVCF compared with those of non-vsOVCF.Study Design/Setting
This is a retrospective, case-control study.Patient Sample
A total of 167 consecutive patients (210 vertebral bodies) who underwent PBK for OVCF between March 2010 and January 2015 were assessed.Outcome Measures
Visual analog scale (VAS) scores for back pain, Korean Oswestry disability index (K-ODI) scores, vertebral body height variations, and kyphotic angles were evaluated preoperatively, postoperatively, and 1 year after treatment.Materials and Methods
Patients in the non-vsOVCF group (anterior vertebral compression of more than two-thirds on plain radiograph) who had undergone PBK where compared with those in the non-vsOVCF group (compression between 30% and two-thirds). Clinical and radiological outcomes were compared. In addition, complications were evaluated.Results
In total, 31 patients (33 vertebrae) in the vsOVCF group and 136 patients (177 vertebrae) in the non-vsOVCF group were treated with PBK. Both groups had significant postoperative improvements in the clinical and radiological outcomes (VAS score, K-ODI score, vertebral body height variation, and kyphotic angle). There was no difference regarding the VAS score and the K-ODI score between the two groups at the final follow-up (p>.05). The cement leakage occurred frequently in the vsOVCF group (26 vertebrae, 78.8%) than in the non-vsOVCF group (92 vertebrae, 52.0%), the difference was statistically significant (p<.05). But there was no case that showed neurologic complication or pulmonary embolism caused by cement leakage. The incidence of recollapse was significantly higher in the vsOVCF group (five vertebrae, 15.2%) than in the non-vsOVCF group (seven vertebrae, 4.0%) (p<.05). The incidence of an adjacent segment fracture (vsOVCF group, 6 vertebrae, 18.2%; non-vsOVCF group, 21 vertebrae, 11.9%) was not significantly different (p=.320).Conclusions
Percutaneous balloon kyphoplasty is a safe and effective procedure for the treatment of vsOVCF. 相似文献11.

Background Context
Although a number of prognostic factors have been demonstrated to be associated with surgical outcome of degenerative lumbar spinal stenosis (DLSS), no study has investigated the relation between hand grip strength (HGS) and treatment outcome of DLSS.Purpose
The purpose of the present study was to examine the influence of HGS on surgical outcomes after surgery for patients with DLSS.Study Design
This is an observational study.Patient Sample
Patients who underwent spine surgery for DLSS were included in the study.Outcome Measures
Oswestry Disability Index (ODI), EuroQOL (EQ-5D), and visual analog scale (VAS) scores for back or leg pain were assessed.Materials and Methods
A total of 172 consecutive patients who underwent spine surgery for DLSS were included in the present study. Patients were assigned to either high HGS group (≥26?kg for men and ≥18?kg for women, n=124) or low HGS group (<26?kg for men and <18?kg for women, n=48) based on their preoperative HGS performance. Oswestry Disability Index, EQ-5D, and VAS scores for back and leg pain were assessed and compared between two groups preoperatively, 3 and 6 months after surgery. The primary outcome measure was baseline-adjusted ODI scores 6 months after surgery. The secondary outcome measures, including the overall ODI score, EQ-5D score, VAS score for back and leg pain, were assessed at each time point during the 6-month follow-up period.Results
As primary outcome, baseline-adjusted ODI scores were significantly lower in the high HGS group than in the low HGS group 6 months after surgery. In the secondary outcome measurements, the ODI, EQ-5D, and VAS scores for back and leg pain improved significantly with time after surgery in both groups. The effects of HGS group on the overall changes in the ODI and EQ-5D scores during the 6-month period were significantly different between the two groups; however, they were not significantly different on VAS score for back and leg pain. The pattern of change in the ODI during the follow-up period was significantly different between the two groups.Conclusions
Patients with preoperative high HGS display better surgical outcome in terms of disability and health status 6 months after spine surgery. Preoperative HGS can act as a predictor of surgical outcome in patients with DLSS. 相似文献12.

Background Context
Determining pain intensity is largely dependent on the patient's report.Purpose
The objective of this study was to test the hypothesis that patients initially reporting a pain score of 10 out of 10 on the visual analog scale (VAS) would experience symptom improvement to a degree similar to patients reporting milder pain.Study Design
This study is a retrospective chart review.Patient Sample
A total of 6,779 patients seeking care for spinal disorders were included in the study.Outcome Measures
The outcome measures used in the study were pain scores on the VAS pain scale, smoking status, morbid depression, gender, and the presence of known secondary gain.Materials and Methods
Patients with lumbar degenerative disk disease with or without spinal stenosis who reported a VAS pain score of 10 out of 10 were identified. Changes in reported VAS pain, patient age, smoking status, morbid depression, gender, and the presence of known secondary gain were examined.Results
A total of 160 individuals (2.9%) reported a maximum pain score of 10 out of 10 on a VAS at their initial presentation. The patients had a median improvement of 3 points in reported VAS pain between the first visit and the last follow-up appointment. The odds to improve by at least 40% on the VAS were 1.500 (95% confidence interval 1.090–2.065) compared with patients reporting submaximal pain. The proportion of patients with identifiable secondary gain was higher (p=.001) than that of patients with submaximal pain. Patients whose pain scores improved dramatically (ie, at least 4 points on the VAS) tended to be older (p=.001), to less often have secondary gain from their disease (p=.007), and to have a negative current smoking status (p=.002). Patients whose pain remained 10 out of 10 during the course of treatment smoked more frequently (p=.016).Conclusions
Our analysis supports the need to consider the influence of secondary gain on the patients' reported VAS pain scores. Maximum pain seems to be a more acute phenomenon with some likelihood to significantly improve. 相似文献13.

Background Context
Although the cervical spine is only occasionally involved in rheumatoid arthritis (RA), involvement of the lumbar spine is even less common. A few reports on lumbar spinal stenosis in patients with RA have appeared. Although disc space narrowing occurs in aging, postoperative adjacent segment disease (ASD) in patients with RA has not been subject to much analysis.Purpose
The objective of this study was to investigate differences in ASD and clinical outcomes between lumbar spinal decompression with and without fusion in patients with RA.Study Design/Setting
This is a retrospective comparative study.Patient Sample
A total of 52 patients with RA who underwent surgery for lumbar spinal disorders were included. Twenty-seven patients underwent decompression surgery with fusion and 25 underwent decompression surgery alone.Outcome Measures
Intervertebral disc space narrowing and spondylolisthesis of the segment immediately cranial to the surgical site were measured using a three-dimensional volume rendering software. Pre- and postoperative evaluation of RA activity and Japanese Orthopaedic Association (JOA) scores were conducted.Materials and Methods
All patients had preoperative and annual postoperative lumbar radiographs and were followed up for a mean of 5.1 years (range 3.5–10.9 years). Pre- and postoperative (2 years after surgery) JOA scores were recorded and any postoperative complications were investigated. Degrees of intervertebral disc narrowing and spondylolisthesis at the adjacent levels were evaluated on radiographs and were compared between the two groups. Analysis was performed to look for any correlation between ASD and RA disease activities.Results
Postoperative JOA scores were significantly improved in both groups. The rate of revision surgery was significantly higher in the fusion group than that in the non-fusion group. The rate of ASD was significantly greater in the fusion group than that in the non-fusion group at the final follow-up examination. Both matrix metalloproteinase 3 (MMP-3) and the 28-joint disease activity score incorporating C-reactive protein levels (DAS28-CRP) were significantly associated with the incidence and severity of ASD.Conclusions
Adjacent segment disease and the need for revision surgery were significantly higher in the fusion group than those in the non-fusion group. A preoperative high MMP-3 and DAS28-CRP are likely to be associated with postoperative ASD. 相似文献14.

Background Context
Despite the fact that ossification of posterior longitudinal ligament (OPLL) is a three-dimensional disease, conventional studies have focused mainly on a two-dimensional measurement, and it is difficult to accurately determine the volume of OPLL growth and analyze the factors affecting OPLL growth after posterior decompression (laminoplasty or laminectomy and fusion).Purpose
The present study aimed to investigate the factors affecting OPLL volume growth using a three-dimensional measurement.Study Design/Setting
This was a retrospective case study.Patient Sample
Eighty-three patients with cervical OPLL who were diagnosed as having multilevel cervical OPLL of more than three levels on cervical computed tomography (CT) scans were retrospectively reviewed from June 1, 1998, to December 31, 2015.Outcome Measures
The OPLL volume from the C1 vertebrae to the C7 vertebrae was measured on preoperative and the most recent follow-up CT scans.Methods
Eighty-three patients were retrospectively examined for age, gender, body mass index, hypertension, diabetes, type of OPLL, surgical method, preoperative cervical curvature, and preoperative and postoperative cervical range of motion. Preoperative cervical CT and the most recent follow-up cervical CT scans were converted to Digital Imaging and Communications in Medicine data, and the OPLL volume was three-dimensionally measured using the Mimics program (Materialise, Leuven, Belgium). The OPLL volume growth was analyzed using univariate and multivariate analyses.Results
The average follow-up period was 32.36 (±23.39) months. Patients' mean age was 54.92 (±8.21) years. In univariate analysis, younger age (p=.037) and laminoplasty (p=.012) were significantly associated with a higher mean annual growth rate of OPLL (%/y). In multivariate analysis, only laminoplasty (p=.027) was significantly associated with a higher mean annual growth rate of OPLL (%/y). The mean annual growth rate of OPLL was about seven times faster with laminoplasty (8.00±13.06%/y) than with laminectomy and fusion (1.16±9.23%/y).Conclusions
Posterior instrumented fusion has the effect of reducing OPLL growth rate compared with motion-preserving laminoplasty. Patients' age and the surgical method need to be considered in surgically managing the multilevel OPLL. 相似文献15.

Background Context
Laminectomy with posterior lumbar interbody fusion (PLIF) has been shown to achieve satisfactory clinical outcomes, but it leads to potential adverse consequences associated with extensive disruption of posterior bony and soft tissue structures.Purpose
This study aimed to compare the clinical and radiographic outcomes of bilateral decompression via a unilateral approach (BDUA) with transforaminal lumbar interbody fusion (TLIF) and laminectomy with PLIF in the treatment of degenerative lumbar spondylolisthesis (DLS) with stenosis.Study Design
This is a prospective cohort study.Patient Sample
This study compared 43 patients undergoing BDUA+TLIF and 40 patients undergoing laminectomy+PLIF.Outcome Measures
Visual analog scale (VAS) for low back pain and leg pain, Oswestry Disability Index (ODI), and Zurich Claudication Questionnaire (ZCQ) score.Methods
The clinical outcomes were assessed, and intraoperative data and complications were collected. Radiographic outcomes included slippage of the vertebra, disc space height, segmental lordosis, and final fusion rate. This study was supported by a grant from The National Natural Science Foundation of China (81572168).Results
There were significant improvements in clinical and radiographic outcomes from before surgery to 3 months and 2 years after surgery within each group. Analysis of leg pain VAS and ZCQ scores showed no significant differences in improvement between groups at either follow-up. The mean improvements in low back pain VAS and ODI scores were significantly greater in the BDUA+TLIF group than in the laminectomy+PLIF group. No significant difference was found in the final fusion rate at 2-year follow-up. The BDUA+TLIF group had significantly less blood loss, shorter length of postoperative hospital stay, and lower complication rate compared with the laminectomy+PLIF group.Conclusions
When compared with the conventional laminectomy+PLIF procedure, the BDUA+TLIF procedure achieves similar and satisfactory effects of decompression and fusion for DLS with stenosis. The BDUA+TLIF procedure appears to be associated with less postoperative low back discomfort and quicker recovery. 相似文献16.
Background Context
Resulting from recent studies that suggest a benefit of implant design on the achievement of fusion and stability in cervical spinal disease management, manufacturing development has increased over the past years. This article attempts to describe how the development of patient-specific implants, which are used during the procedures of anterior cervical corpectomy and vertebral body replacement (VBR), impacts the outcomes of cervical spondylotic myelopathy (CSM) management.Materials and Methods
This prospective clinical study included six patients who were implanted with patient-specific VBR for single-level or multilevel CSM. The following clinical scores were collected: visual analog scale (VAS), modified Japanese Orthopaedic Association (mJOA), Neck Dysfunction Index (NDI), and European myelopathy score (EMS), along with radiological measurements.Results
Six patients reached a mean follow-up date of 21months (12–24). Angle measurements remained constant during follow-up, including the C2–C7 Cobb angle and the corpectomy Cobb angle. Furthermore, no deformations, such as hyperlordosis or kyphosis, were detected. The anterior height (Ha) and the posterior height (Hp) of the corpectomy segment remained constant (ratio close to 1) with no severe subsidence (>3?mm) at the last follow-up. No height differences were detected between the preoperative and the last follow-up dates, neither for the upper Hp and Ha (0.97±0.09 and 1.00±0.06, respectively) nor for the lower adjacent vertebrate Hp and Ha (0.96±0.04 and 1.02±0.12). The mean mJOA and EMS recovery rates were 60.4% (standard deviation [SD] 20.4) and 77.0% (SD 29.7), respectively, at last the follow-up. An EMS of at least 16 of 18 was observed in 83% (5 of 6) of the patients. We recorded a preoperative NDI score at 47.1% (SD 18.6) that improved to 11.2% (SD 4.1) at the last follow-up (p<.01). The preoperative VAS neck (6.3, range 4–7) and the VAS arm (6.1, range 3– 9) scores improved to 1.3 (range 0–3) and 2.8 (range 0–5), respectively, at the last follow-up.Conclusions
This preliminary report suggests a possible benefit of the use of patient-specific implants in CSM treatment. The favorable clinical and radiological outcomes were associated with a correct achievement rate; these are promising elements toward the development of the concept of personalized therapy. Nonetheless, these encouraging results have to be confirmed now with a longer follow-up and a larger cohort. 相似文献17.
Background Context
Radiofrequency denervation is commonly used for the treatment of chronic facet joint pain that has been refractory to more conservative treatments, although the evidence supporting this treatment has been controversial.Purpose
We aimed to elucidate the precise effects of radiofrequency denervation in patients with low back pain originating from the facet joints relative to those obtained using control treatments, with particular attention to consistency in the denervation protocol.Study Design/Setting
A meta-analysis of randomized controlled trials was carried out.Patient Sample
Adult patients undergoing radiofrequency denervation or control treatments (sham or epidural block) for facet joint disease of the lumbar spine comprised the patient sample.Outcome Measures
Visual analog scale (VAS) pain scores were measured and stratified by response of diagnostic block procedures.Method
We searched PubMed, Embase, Web of Science, and the Cochrane Database for randomized controlled trials regarding radiofrequency denervation and control treatments for back pain. Changes in VAS pain scores of the radiofrequency group were compared with those of the control group as well as the minimal clinically important difference (MCID) for back pain VAS. Meta-regression model was developed to evaluate the effect of radiofrequency treatment according to responses of diagnostic block while controlling for other variables. We then calculated mean differences and 95% confidence intervals (CIs) using random-effects models.Results
We included data from seven trials involving 454 patients who had undergone radiofrequency denervation (231 patients) and control treatments such as sham or epidural block procedures (223 patients). The radiofrequency group exhibited significantly greater improvements in back pain score when compared with the control group for 1-year follow-up. Although the average improvement in VAS scores exceeded the MCID, the lower limit of the 95% CI encompassed the MCID. A subgroup of patients who responded very well to diagnostic block procedures demonstrated significant improvements in back pain relative to the control group at all times. When placed into our meta-regression model, the response to diagnostic block procedure was responsible for a statistically significant portion of treatment effect. Studies published over the last two decades revealed that radiofrequency denervation reduced back pain significantly in patients with facet joint disease compared with the MCID and control treatments.Conclusions
Conventional radiofrequency denervation resulted in significant reductions in low back pain originating from the facet joints in patients showing the best response to diagnostic block over the first 12 months when compared with sham procedures or epidural nerve blocks. 相似文献18.

Background Context
Conventional anterior decompression surgery for cervical myelopathy, including anterior corpectomy and fusion, is technically demanding and is known to be associated with a higher incidence of surgery-related complications, including cerebrospinal fluid (CSF) leakage, neurologic deterioration, and graft failure compared with posterior surgery.Purpose
We introduce a novel anterior decompression technique (vertebral body sliding osteotomy [VBSO]) for cervical myelopathy caused by ossification of posterior longitudinal ligament (OPLL) and evaluate the efficacy and safety of this procedure.Study Design
This is a case series for novel surgical technique.Patient Sample
Fourteen patients (M:F=11:3, mean age 56.9±10) with cervical myelopathy caused by OPLL who underwent VBSO by a single surgeon were included.Outcome Measures
The surgical outcome was evaluated according to the Japanese Orthopaedic Association score for cervical myelopathy (C-JOA score), and the recovery rate of the C-JOA score was calculated. Patients were also evaluated radiographically with plain and dynamic cervical spine radiographs and pre- and postoperative computed tomography images.Methods
Fourteen patients were followed up for more than 24 months, and operation time, estimated blood loss, neurologic outcomes, and surgery-related complications were investigated. Radiological measurements were also performed to analyze the following parameters: (1) canal-occupying ratio and postoperative canal widening, and (2) pre- and postoperative sagittal alignment.Results
The mean recovery rate of C-JOA score at the final follow-up was 68.65±17.8%. There were no perioperative complications, including neurologic deterioration, vertebral artery injury, esophageal injury, graft dislodgement, and CSF leaks, after surgery except for pseudarthrosis in one case. An average spinal canal compromised ratio by OPLL decreased from 61.5±8.1% preoperatively to 16.5±11.2% postoperatively. An average postoperative canal widening was 5.15±1.39?mm, and improvement of cervical alignment was observed in all patients, with average recovery angle of 7.3±6.1° postoperatively.Conclusions
The VBSO allows sufficient decompression of spinal cord and provides excellent neurologic outcomes. Because surgeons do not need to manipulate the OPLL mass directly, this technique could significantly decrease surgery-related complications. Furthermore, as VBSO is based on the multilevel discectomy and fusion technique, it would be more helpful to restore a physiological lordosis. 相似文献19.

Background Context
A spinal infection is a serious problem for a spine surgeon, and there is currently much debate regarding how best to treat pyogenic spondylodiscitis using antibiotics and the instrumentations that have been developed to date.Purpose
The purpose of this study was to determine which method is better for treating pyogenic spondylodiscitis.Study Design
A retrospective chart review was performed.Patient Sample
Thirty-one patients with pyogenic spondylodiscitis underwent surgical treatment between 2000 and 2016 at the authors' institution.Outcome Measures
Clinical outcomes were assessed using a visual analog scale (VAS). We measured translation and rotation on flexion and extension X-rays to identify instability.Methods
Patients were divided into two groups: Group I, decompression group; Group II, decompression plus fusion group. Group I exhibited no instability according to a preoperative radiographic study, whereas Group II exhibited instability. Both groups were compared with respect to demographics and laboratory findings, including tests to determine C-reactive protein (CRP) levels and erythrocyte sedimentation rates (ESR), organisms, and the total duration of antibiotic treatment after the operation. We compared the results of the preoperative, postoperative, and last follow-up radiographic examinations of the sagittal alignment of the infected segment. This study was supported by a clinical research fund (4,500 dollars) from the National Health Insurance Service, Ilsan Hospital.Results
A total of 31 patients were included; 22 (71%) were in Group I and 9 (29%) were in Group II. On radiological examination, the mean preoperative translation and rotation values in Group I were 2.45±1.22?mm and 5.64±1.98°, and in Group II were 5.35±1.65?mm and 12.01±4.22°. At the last follow-up, the mean translation and rotation values in Group I were 1.95±1.75?mm and 2.69±1.61°, and in Group II were 1.77±1.02?mm and 3.44±2.07°. Both Groups I and II exhibited stability after the operation. No differences were detected in preoperative ESR and CRP levels between the two groups. Group I, compared with Group II, experienced a shorter duration of treatment with antibiotics and normalization of ESR and CRP levels after the operation and a shorter hospitalization period.Conclusions
If the appropriate antibiotics are administered quickly when there is no instability, decompression alone is effective; however, if instability is detected, decompression plus fusion can be used to achieve stability. 相似文献20.
