Background Context
Even though catastrophizing can negatively moderate the outcome of surgery for lumbar spinal stenosis (LSS), it is still unclear whether pain catastrophizing is an enduring stable or a dynamic structure related to pain intensity after spine surgery.Purpose
The purpose of this study was to determine whether catastrophizing would change in patients who undergo spinal surgery for LSS.Study Design
A prospective observational cohort study was carried out.Study Sample
Patients who underwent spine surgery for LSS comprised the study sample.Outcome Measures
The Visual Analog Pain Scale (VAS) scores for back/leg pain, Oswestry Disability Index (ODI), and Pain Catastrophizing Scale (PCS) were the outcome measures.Methods
The present observational cohort consisted of 138 patients between the ages of 40 and 80 years who were scheduled to undergo surgery for LSS. Among them, a total of 96 patients underwent a 3-year assessment after surgery. The PCS questionnaire was used for pain catastrophizing assessment before and 3 years after surgery. The VAS for back and leg pain, and ODI were assessed 3 and 6 months, and 1 and 3 years after surgery. The correlations between variables were analyzed before and 3 years after surgery. To clarify the causal relationship, time-series and linear mixed models were also used.Results
At 3 years after surgery, ODI, VAS for back and leg pain, and PCS scores were significantly decreased. The correlation of PCS with VAS and ODI was significant both before and 3 years after surgery. The correlation between change in pain or disability and change in pain catastrophizing from preoperative to 3 years after surgery was also significant. In the causal relationship between pain and catastrophizing, overall changes in pain and disability were significant predictors of overall changes in pain catastrophizing from baseline to 3 year after surgery.Conclusion
The present study shows that pain catastrophizing can change in association with the improvement in pain intensity after spine surgery. Therefore, catastrophizing may not be an enduring stable construct, but a dynamic construct. 相似文献2.

Background Context
Surgery because of disc herniation or spinal stenosis results mostly in large improvement in the short-term, but mild to moderate improvements for pain and disability at long-term follow-up. Prehabilitation has been defined as augmenting functional capacity before surgery, which may have beneficial effect on outcome after surgery.Purpose
The aim was to study if presurgery physiotherapy improves function, pain, and health in patients with degenerative lumbar spine disorder scheduled for surgery.Study Design
A single-blinded, two-arm, randomized controlled trial (RCT).Patient Sample
A total of 197 patients were consecutively included at a spine clinic. The inclusion criteria were patients scheduled for surgery because of disc herniation, spinal stenosis, spondylolisthesis, or degenerative disc disease (DDD), 25–80 years of age.Outcome Measures
Primary outcome was Oswestry Disability Index (ODI). Secondary outcomes were pain intensity, anxiety, depression, self-efficacy, fear avoidance, physical activity, and treatment effect.Methods
Patients were randomized to either presurgery physiotherapy or standardized information, with follow-up after the presurgery intervention as well as 3 and 12 months post surgery. The study was funded by regional research funds for US$77,342. No conflict of interest is declared.Results
The presurgery physiotherapy group had better ODI, visual analog scale (VAS) back pain, EuroQol-5D (EQ-5D), EQ-VAS, Fear Avoidance Belief Questionnaire-Physical Activity (FABQ-PA), Self-Efficacy Scale (SES), and Hospital Anxiety and Depression Scale (HADS) depression scores and activity level compared with the waiting-list group after the presurgery intervention. The improvements were small, but larger than the study-specific minimal clinical important change (MCIC) in VAS back and leg pain, EQ-5D, and FABQ-PA, and almost in line with MCIC in ODI and Physical Component Summary (PCS) in the physiotherapy group. Post surgery, the only difference between the groups was higher activity level in the physiotherapy group compared with the waiting-list group.Conclusions
Presurgery physiotherapy decreases pain, risk of avoidance behavior, and worsening of psychological well-being, and improves quality of life and physical activity levels before surgery compared with waiting-list controls. These results were maintained only for activity levelspost surgery. Still, presurgery selection, content, dosage of exercises, and importance of being active in a presurgery physiotherapy intervention is of interest to study further to improve long-term outcome. 相似文献3.
Background Context
Percutaneous endoscopic lumbar discectomy (PELD) is one of minimally invasive techniques to treat patients with low back and radiating pain resulting from lumbosacral disc herniation (LDH).Purpose
The purpose of this study is to evaluate the clinical efficacy of PELD to treat patients with low back and radicular pain due to LDH and to investigate which clinical and radiological variables have the ability to predict clinical outcome after PELD.Study design/setting
This is a retrospective study design carried out at a spine hospital.Patient sample
The sample comprised 75 patients who had undergone PELD for treatment of low back and radiating leg pain resulting from LDH and who could be followed up for at least 12 months.Outcomes measures
Clinical outcomes were assessed using numeric rating scale for back and radiating leg pain (NRS back and leg), Oswestry Disability Index (ODI), and modified MacNab criteria at 1 month (short-term follow-up) and at least 12 months (long-term follow-up) after PELD.Methods
The patients were divided into successful and unsuccessful outcome groups according to improvement of NRS back, NRS leg, and ODI (%) at long-term follow-up period. We compared the various clinical and radiological variables between the two groups to identify which variables could be the prognostic factors of clinical outcomes of PELD. This analysis was performed in terms of whole population, the subgroup of dominant back pain, and the subgroup of dominant leg pain, respectively.Results
Significant improvements were observed in NRS back, NRS leg, ODI (%), and modified MacNab criteria at short-term and long-term follow-up after PELD. Positive straight leg raising (SLR) was significantly related to successful outcome as to NRS leg and ODI (%), and longer pain duration also showed significant relationship with unsuccessful outcomes as to NRS leg in whole population. Positive SLR had significant relationship with successful NRS leg as well as successful ODI (%) in the subgroup of dominant leg pain.Conclusions
PELD was an effective treatment in patients with back and leg pain due to LDH. Positive SLR had the predictive ability to successful reduction of radiating leg pain and successful functional improvement. Longer pain duration was also related to unsuccessful reduction of radiating leg pain. 相似文献4.

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5.

Background Context
Proper patient selection is of utmost importance in the surgical treatment of degenerative disc disease (DDD) with chronic low back pain (CLBP). Among other factors, gender was previously found to influence lumbar fusion surgery outcome.Purpose
This study investigates whether gender affects clinical outcome after lumbar fusion.Study Design
This is a national registry cohort study.Patient sample
Between 2001 and 2011, 2,251 men and 2,521 women were followed prospectively within the Swedish National Spine Register (SWESPINE) after lumbar fusion surgery for DDD and CLBP.Outcome measures
Patient-reported outcome measures (PROMs), visual analog scale (VAS) for leg and back pain, Oswestry Disability Index (ODI), quality of life (QoL) parameter EQ5D, and labor status and pain medication were collected preoperatively, 1 and 2 years after surgery.Methods
Gender differences of baseline data and PROM improvement from baseline were analyzed. The effect of gender on clinically important improvement of PROM was determined in a multivariate logistic regression model. Furthermore, gender-related differences in return-to-work were investigated.Results
Preoperatively, women had worse leg pain (p<.001), back pain (p=.002), lower QoL (p<.001), and greater disability than men (p=.001). Postoperatively, women presented greater improvement 2 years from baseline for pain, function, and QoL (all p<.01). Women had better chances of a clinically important improvement than men for leg pain (odds ratio [OR]=1.39, 95% confidence interval [CI]: 1.19–1.61, p<.01) and back pain (OR=1.20,95% CI:1.03–1.40, p=.02) as well as ODI (OR=1.24, 95% CI:1.05–1.47, p=.01), but improved at a slower pace in leg pain (p<.001), back pain (p=.009), and disability (p=.008). No gender differences were found in QoL and return to work at 2 years postoperatively.Conclusions
Swedish women do not have worse results than men after spinal fusion surgery. Female patients present with worse pain and function preoperatively, but improve more than men do after surgery. 相似文献6.

Background Context
Medical interventional modalities such as lumbar epidural steroid injections (LESIs) are often used in the setting of lumbar spine disorders where other conservative measures have failed. Concomitant depression can lead to worse outcomes in lumbar spine pathology. A number of studies have demonstrated an association between preoperative depression and poor outcomes following surgery, but the effect of depression on outcomes following medical interventional modalities is poorly understood.Purpose
To evaluate the differences in patient-reported outcomes (PROs) between depressed and non-depressed patients undergoing LESI.Study Design/Setting
This study is an analysis of a prospective longitudinal registry database at a single academic institution.Patient Sample
All patients undergoing LESI from 2012 to 2014 were eligible for enrollment into a prospective, web-based registry. Eligible patients had radicular pain, correlative imaging findings of degenerative pathology, and failed 6 weeks of conservative care.Outcome Measures
The PROs measured included the (1) numeric rating scale for back pain (NRS-BP), (2) numeric rating scale for leg pain (NRS-LP), (3) disease-specific physical disability—Oswestry Disability Index (ODI), and (4) preference-based health status—EuroQol-5D (EQ-5D).Materials and Methods
Patients who met the inclusion criteria underwent LESI. Patient-reported outcomes were collected at baseline and at 12 months following treatment. Based on previously validated values for the Zung Depression Scale (ZDS) as a screening tool for depression, patients were dichotomized into non-depressed (ZDS score ≤33) and depressed (ZDS score >33). The PRO change scores from baseline to 12 months were calculated. The mean absolute and change scores between the groups were compared using Student t test. Multivariable linear regression analysis for ODI, EQ-5D, NRS-LP, and NRS-BP was performed.Results
A total of 161 patients with complete 12-month follow-up were included. Seventy-one patients (44%) were classified as depressed and 90 patients (56%) were classified as non-depressed. The mean baseline PRO scores were significantly worse in depressed patients compared with non-depressed patients: ODI (p<.001), NRS-BP (p=.013), NRS-LP (p<.001), and EQ-5D (p=.001). The mean absolute scores at 12 months were significantly lower in the depressed versus non-depressed patients: ODI (p<.001), NRS-BP (p=.001), NRS-LP (p=.05), and EQ-5D (p=.003). However, there was no difference in mean change scores observed at 12 months between the depressed and non-depressed cohorts: ODI (p=.42), NRS-BP (p=.31), NRS-LP (p=.25), EQ-5D (p=.14). Adjusting for pre-procedure variables, the higher ZDS score was associated with higher disability (ODI) at 12 months.Conclusions
Depression led to worse absolute scores for PROs and is associated with higher disability following LESI. However, patients with depressive symptoms can expect similar improvement in PROs at 12 months. 相似文献7.

Background Context
The Timed Up and Go (TUG) test has recently been proposed as a simple and standardized measure for objective functional impairment (OFI) in patients with lumbar degenerative disc disease (DDD).Purpose
The study aimed to explore the relationship between a patient's mental health status and both patient-reported outcome measures (PROMs) and TUG test results.Study Design/Setting
This is a prospective institutional review board-approved two-center study.Patient Sample
The sample was composed of 375 consecutive patients scheduled for lumbar spine surgery and a healthy cohort of 110 control subjects.Outcome Measures
Patients and control subjects were assessed with the TUG test and a comprehensive panel of subjective PROMs of pain intensity (visual analog scale [VAS]), functional impairment (Roland-Morris Disability Index [RMDI]), Oswestry Disability Index [ODI]), as well as health-related quality of life (hrQoL; Euro-Qol [EQ]-5D).Methods
Standardized age- and sex-adjusted TUG test T-scores were calculated. The dependent variable was the short-form (SF)-12 mental component summary (MCS) quartiles, and the independent variables were the TUG T-scores and PROMs. Direct and adjusted analyses of covariance were performed to estimate the interaction between the SF-12 MCS quartiles and the independent variables.Results
In patients, there was a significant decrease in the subjective PROMs, notably the VAS back pain (p=.001) and VAS leg pain (p=.035), as well as significant increase in the RMDI (p<.001), ODI (p<.001), and the EQ-5D index (p<.001) with every increase in the quartile of the SF-12 MCS. There were no significant group differences of OFI as measured by the TUG T-scores across the SF-12 MCS quartiles (p=.462). In the healthy control group, a significant decrease in VAS leg pain (p=.028), RMDI (p=.013), and ODI (p<.001), as well as a significant increase in the EQ-5D index (p<.001), was seen across the SF-12 MCS quartiles, whereas TUG T-scores remained stable (p=.897).Conclusions
There are significant influences of mental hrQoL on subjective measures of pain, functional impairment, and hrQoL that might lead to bias when evaluating patients with lumbar DDD who suffer from reduced mental hrQoL. The TUG test appears to be a stable instrument and especially helpful in the evaluation of patients with lumbar DDD and mental health problems. 相似文献8.

Background Context
Although lumbar disc herniation (LDH) classically presents with lower extremity radiculopathy, there are patients who have substantial associated back pain.Purpose
The present study aims to determine if patients with LDH with substantial back pain improve with decompression alone.Study Design
This is a longitudinal observational cohort study.Patient Sample
Patients enrolled in the Quality and Outcomes Database with LDH and a baseline back pain score of ≥5 of 10 who underwent single- or two-level lumbar discectomy only.Outcome Measures
Back and leg pain scores (0–10), Oswestry Disability Index (ODI), and EuroQoL 5D were measured.Methods
Standard demographic and surgical variables were collected, as well as patient-reported outcomes at baseline and at 3 and 12 months postoperatively.Results
The mean age of the cohort was 49.8 years and 1,195 (52.8%) were male. Mean body mass index was 30.1?kg/m2. About half of the patients (1,103, 48.8%) underwent single-level discectomy and the other half (1,159, 51.2%) had two-level discectomy. Average blood loss was 44?cc. Most of the patients (2,217, 98%) were discharged home with routine postoperative care. The average length of stay was 0.53 days. At 3 and 12 months postoperatively, there were statistically significant (p<.000) improvements in back pain (from 7.7 to 2.9 to 3.2), leg pain (from 7.5 to 2.3 to 2.5), and ODI (from 26.2 to 11.6 to 11.2). Patients with a single-level discectomy, compared with patients with a two-level discectomy, had similar improvements in 3- and 12-month back pain, leg pain, and ODI scores.Conclusions
Patients with LDH who have substantial back pain can be counseled to expect improvement in their back pain scores 12 months after a discectomy. 相似文献9.

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10.

Background Context
Lumbar total disc replacement (TDR) is a treatment option for selected patients with chronic low back pain (LBP) that is non-responsive to conservative treatment. The long-term results of disc replacement compared with multidisciplinary rehabilitation (MDR) have not been reported previously.Purpose
We aimed to assess the long-term relative efficacy of lumbar TDR compared with MDR.Design
We undertook a multicenter randomized controlled trial at five university hospitals in Norway.Patient Sample
The sample consisted of 173 patients aged 25–55 years with chronic LBP and localized degenerative changes in the lumbar intervertebral discs.Outcome Measures
The primary outcome was self-reported physical function (Oswestry Disability Index [ODI]) at 8-year follow-up in the intention-to-treat population. Secondary outcomes included self-reported LBP (visual analogue scale [VAS]), quality of life (EuroQol [EQ-5D]), emotional distress (Hopkins Symptom Checklist [HSCL-25]), occupational status, patient satisfaction, drug use, complications, and additional back surgery.Methods
Patients were randomly assigned to lumbar TDR or MDR. Self-reported outcome measures were collected 8 years after treatment. The study was powered to detect a difference of 10 ODI points between the groups. The study has not been funded by the industry.Results
A total of 605 patients were screened for eligibility, of whom 173 were randomly assigned treatment. Seventy-seven patients (90%) randomized to surgery and 74 patients (85%) randomized to rehabilitation responded at 8-year follow-up. Mean improvement in the ODI was 20.0 points (95% confidence interval [CI] 16.4–23.6, p≤.0001) in the surgery group and 14.4 points (95% CI 10.7–18.1, p≤.0001) in the rehabilitation group. Mean difference between the groups at 8-year follow-up was 6.1 points (95% CI 1.2–11.0, p=.02). Mean difference in favor of surgery on secondary outcomes were 9.9 points on VAS (95% CI 0.6–19.2, p=.04) and 0.16 points on HSCL-25 (95% CI 0.01–0.32, p=.04). There were 18 patients (24%) in the surgery group and 4 patients (6%) in the rehabilitation group who reported full recovery (p=.002). There were no significant differences between the groups in EQ-5D, occupational status, satisfaction with care, or drug use. In the per protocol analysis, the mean difference between groups was 8.1 ODI points (95% CI 2.3–13.9, p=.01) in favor of surgery. Forty-three of 61 patients (70%) in the surgery group and 26 of 52 patients (50%) in the rehabilitation group had a clinically important improvement (15 ODI points or more) from baseline (p=.03). The proportion of patients with a clinically important deterioration (six ODI points or more) was not significantly different between the groups. Twenty-one patients (24%) randomized to rehabilitation had crossed over and had undergone back surgery since inclusion, whereas 12 patients (14%) randomized to surgery had undergone additional back surgery. One serious adverse event after disc replacement is registered (<1%).Conclusions
Substantial long-term improvement can be expected after both disc replacement and MDR. The difference between groups is statistically significant in favor of surgery, but smaller than the prespecified clinically important difference of 10 ODI points that the study was designed to detect. Future research should aim to improve selection criteria for disc replacement and MDR. 相似文献11.

Background
Comprehensive assessment of quality of care includes patient-reported outcomes, safety of care delivered, and patient satisfaction. The impact of the patient-reported Oswestry Disability Index (ODI) scores at baseline and 12 months on satisfaction with outcomes following spine surgery is not well documented.Purpose
This study aimed to determine the impact of patient disability (ODI) scores at baseline and 12 months on satisfaction with outcomes following surgery.Study Design
Analysis of prospectively collected longitudinal web-based multicenter data.Patient Sample
Patients undergoing elective surgery for degenerative lumbar disease were entered into a prospective multicenter registry.Outcome Measures
Primary outcome measures were ODI, North American Spine Society satisfaction (NASS) questionnaire.Methods
Baseline and 12-month ODI scores were recorded. Satisfaction at 12 months after surgery was measured using NASS questionnaire. Multivariable proportional odds logistic regression analysis was conducted to determine the impact of baseline and 12-month ODI on satisfaction with outcomes.Results
Of the total 5,443 patients, 64% (n=3,460) were satisfied at a level where surgery met their expectations (NASS level 1) at 12 months after surgery. After adjusting for all baseline and surgery-specific variables, the 12-month ODI score had the highest impact (Wald χ2=1,555, 86% of the total χ2) on achieving satisfaction with outcomes compared with baseline ODI scores (Wald χ2=93, 5% of the total χ2). The level of satisfaction decreases with increasing 12-month ODI score. Greater change in ODI is required to achieve a better satisfaction level when the patient starts with a higher baseline ODI score.Conclusion
Absolute 12-month ODI following surgery had a significant association on satisfaction with outcomes 12 months after surgery. Patients with higher baseline ODI required a larger change in ODI score to achieve satisfaction. No single measure can be used as a sole yardstick to measure quality of care after spine surgery. Satisfaction may be used in conjunction with baseline and 12-month ODI scores to provide an assessment of the quality of spine surgery provided in a patient centric fashion. 相似文献12.

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14.
Background Context
Epidural steroid injection is commonly used in patients with chronic low back pain. Applying a mixture of a local anesthetic (LA) and steroid using the interlaminar (IL), transforaminal, and caudal techniques is a preferred approach.Purpose
The present study aims to investigate the efficacy of interlaminar epidural steroid administration in patients with multilevel lumbar disc pathology (LDP) and to assess the possible correlation of the procedure's success with age and body mass index (BMI).Study Design
A randomized controlled trial was performed.Patient Sample
We administered interlaminar epidural steroid to a total of 98 patients with multilevel LDP.Outcome Measures
The visual analog scale (VAS) and Oswestry Disability Index (ODI) scoring were performed on the study population at pretreatment (PRT), posttreatment, and 1, 3, 6, and 12 PRT months. A possible correlation of BMI and age with the procedure success was evaluated.Methods
The LA group (Group L, n=50) received 10?mL 0.25% bupivacaine, whereas the steroid+LA group (Group S, n=48) received 10?mL 0.25% bupivacaine+40?mg methylprednisolone at L4–L5 intervertebral space in prone position under the guidance of C-arm fluoroscopy.Results
There was no statistical difference in the PRT VAS and ODI scores between the groups (p<.05), whereas the VAS and ODI scores at 1, 3, 6, and 12 posttreatment months were higher in Group L, compared with Group S (p<.05). Age and BMI were not found to be related with the success of the procedure.Conclusions
Our study results showed that the VAS and ODI scores were lower in patients with multilevel LDP receiving steroid, following the administration of IL epidural injection. However, further studies are required to establish a robust conclusion on the dispersion of IL epidural injections in the epidural area and the dose of steroid. 相似文献15.
Purpose
There are two, principally different ways to obtain patient opinions regarding the outcome of spine surgery: using prospective multi-item questionnaires preoperatively and at follow-up, and using a retrospective single-item question at follow-up—both methods have distinct advantages and limitations. The purpose of the study was to explore the utility of using the simple transition question global assessment, GA, (“How is your back/leg pain today as compared to before the surgery?”) as an overall patient-reported outcome measure (PROM) based on the large real-life database in the Swedish spine registry (Swespine).Methods
The correlation between GA and the score-changes and the final scores at 1 year of follow-up for the PROMs VAS, ODI, and EQ-5D was examined. The correlations between GA and item-specific domains within the ODI, EQ-5D and SF-36 as well as the discriminative ability of PROMs with GA as reference criterion were also analysed. The cohort consisted of 94,132 patients registered in Swespine who were surgically treated for disc herniation, spinal stenosis or degenerative disc disease.Results
The correlation coefficients for GA vs. the score-changes were lower than for GA vs final scores. For VAS they ranged for the different diagnosis groups from 0.33 to 0.61 and from 0.50 to 0.79, respectively. For ODI, the corresponding values ranged from 0.43 to 0.65 and 0.63 to 0.76; for the EQ-5D from 0.32 to 0.45 and 0.54 to 0.71. Further, GA showed a somewhat stronger correlation to pain-specific PROMs than to quality-of-life PROMs.Conclusions
The single-item outcome measure global assessment (GA) appears to be a feasible overall patient-reported outcome measure (PROM) and a useful reference for interpreting the scores of patient-reported outcome measures.16.

Background Context
Preoperative depression is increasingly understood as an important predictor of patient outcomes after spinal surgery. In this study, we examine the relationship between depression and patient-reported functional outcomes (PRFOs), including disability and pain, at various time points postoperatively.Purpose
The objective of this study was to analyze the use of depression, as measured by the 9-Item Patient Health Questionnaire (PHQ-9), as a means of assessing postoperative patient-reported disability and pain.Study Design/Setting
This study includes an analysis of prospective non-randomized spine registry compiled through an academic multispecialty group practice model.Patient Sample
A total of 1,000 spinal surgery patients from an affiliated surgical registry, enrolled from January 2010 onward, were included in this study.Outcome Measures
Pain was assessed via the visual analog scale (VAS) for leg or back pain. Disability was measured by the Oswestry Disability Index (ODI). Depression was measured by the PHQ-9.Methods
Patient data were collected preoperatively and at 1, 4, 10, and 24 months postoperatively. Data were analyzed via analysis of variance and Pearson correlation coefficient.Results
All patient stratifications analyzed experienced improvements in pain and ability postoperatively, as measured by the VAS and the ODI, respectively. Moderately and severely depressed patients (as measured by preoperative PHQ-9) experienced decreases in the mean PHQ-9 score of ?6.00 and ?7.96 24 months after surgery, respectively.Conclusions
In all groups, spinal surgery was followed by relief of pain and improved PRFO. Preoperative depression, as measured by the PHQ-9, predicted postoperative PRFO. Patients with moderate to severe depression as measured by the PHQ-9 experienced large mean decreases in the PHQ-9 score postoperatively. As a psychosocial metric, the PHQ-9 is a useful method of assessing value-added service of a spinal surgery. 相似文献17.

Background Context
Clinical practice guidelines (CPGs) are designed to ensure that evidence-based treatment is easily put into action. Whether patients and clinicians follow these guidelines is equivocal.Purpose
The objectives of this study were to examine how many patients complaining of low back pain (LBP) underwent evidence-based medical interventional treatment in line with CPG recommendations before consultation with a spine surgeon, and to evaluate any associations between adherence to CPG recommendations and baseline factors.Study Design/Setting
This is a cross-sectional cohort analysis at a tertiary care center.Patient Sample
A total of 229 patients were referred for surgical consultation for an elective lumbar spinal condition.Outcome Measures
The outcome measures include the number of CPG-recommended treatments undertaken by patients at or before the time of referral, the validated pain score, the EuroQol-5D (EQ-5D) health status, and the Oswestry Disability Index (ODI) score.Methods
Questionnaires assessing demographic and functional characteristics as well as overall health care use were sent to patients immediately after their referral was received by the surgeon's office.Results
Medications were the most common modality before consultation (74.2% of patients), of which 46.3% received opioids. The number of medications taken was significantly related to a higher ODI score (R=0.23, p=.0004), a higher pain score (R=0.15, p=.026), and a lower EQ-5D health status (R=?0.15, p=.024). In contrast, a lower pain score (7.2 vs. 7.7, p=.037) and a lower ODI score (26.6 vs. 29.9, p=.0023) were associated with performing adequate amounts of exercise. There was a significant association between lower numbers of treatments received and higher numerical pain rating scores (R=?0.14, p=.035). The majority (61.1%) of patients received two or less forms of treatment.Conclusions
Evidence-based medical interventional treatments for patients with LBP are not being taken advantage of before spine surgery consultation. If more patients were to undertake CPG-endorsed conservative modalities, it may result in fewer unnecessary referrals from primary care physicians, and patients might not deteriorate as much while lingering on long wait lists. Further studies incorporating knowledge translation or health system pathway changes are necessary. 相似文献18.

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19.

Background Context
Chronic opioid therapy is associated with worse patient-reported outcomes (PROs) following spine surgery. However, little literature exists on the relationship between opioid use and PROs following epidural steroid injections for radicular pain.Purpose
We evaluated the association between pre-injection opioid use and PROs following spine epidural steroid injection.Study Design
This study is a retrospective analysis of a prospective longitudinal registry database.Patient Sample
A total of 392 patients within our database who were undergoing epidural steroid injections (ESIs) at our institution for degenerative structural spine diagnoses and met our inclusion criteria were included in this study.Outcome Measures
Patient-reported outcomes for disability (Oswestry Disability Index/Neck Disability Index [ODI/NDI)]), quality of life (EuroQol-5D [EQ-5D]), and pain (Numerical Rating Scale scores for back pain, neck pain, leg pain, and arm pain [NRS-BP/NP/LP/AP]) were assessed at baseline and at 3 and 12 months post-injection.Methods
Multivariable proportional odds logistic regression models were created to examine the relationship between pre-injection opioid use and post-injection PROs. A logistic regression with Bayesian Markov chain Monte Carlo parameter estimation was used to investigate a possible cutoff value of pre-injection opioid use above which the effectiveness of ESI (as measured by minimum clinically important difference [MCID] for ODI/NDI) decreases.Results
A total of 276 patients with complete 12-month follow-up following ESI were analyzed. The mean pre-injection daily morphine equivalent amount (MEA) was 14.7?mg (95% confidence interval [CI] 12.4?mg–19.1?mg) for the cohort. Pre-injection opioid use was associated with slightly higher odds of worse disability (odds ratio [OR] 1.03, p=.03) and leg/arm pain (OR 1.01, p=.04) scores at 3 months post-injection only. No significant association between pre-injection opioid use and MCID for ODI/NDI was found, although a cutoff of 55.5?mg/day might serve as a significant threshold.Conclusion
Increased pre-injection opioid use does not impact long-term outcomes after ESIs for degenerative spine diseases. A pre-injection MEA around 50?mg/day may represent a threshold above which the 3-month effectiveness of ESI for back- and neck-related disability decreases. Epidural steroid injection is an effective treatment modality for pain in patients using opioids, and can be part of a multimodal strategy for opioid independence. 相似文献20.
