BACKGROUND CONTEXT
Patients with pyogenic vertebral osteomyelitis (PVO) are expected to have an increased risk of bone loss. Therefore, early bisphosphonate therapy would be clinically effective for PVO patients with osteoporosis.PURPOSE
This study aimed to investigate the effect of bisphosphonate on clinical outcomes of PVO patients with osteoporosis.STUDY DESIGN/SETTING
A retrospective comparative study.PATIENT SAMPLE
PVO patients with osteoporosis.OUTCOME MEASURES
Four events of interest for Cox proportional hazard model included surgical treatment, recurrence of infection, subsequent fracture of adjacent vertebral bodies, and death.METHODS
PVO patients were divided into three groups: group A (initiation of bisphosphonate within 6 weeks after PVO diagnosis), group B (initiation of bisphosphonate between 6 weeks and 3 months after PVO diagnosis), and group C (no treatment for osteoporosis). Cox proportional hazard model was used for the four events of interest.RESULTS
A total of 360 PVO patients with osteoporosis were investigated for the four events of interest. Group A had significantly lower hazard ratios for undergoing later (>6 weeks after diagnosis) surgery than group C (p?=?.014) despite similar occurrences of overall surgery. A significant difference was also observed in the occurrence of subsequent fractures at adjacent vertebral bodies (p?=?.001 for model 1 and p?=?.002 for model 2). Groups A and B had significantly lower hazard ratios for subsequent fracture than group C. No significant differences were observed in the hazard ratios of recurrence and death among the three groups.CONCLUSIONS
Early bisphosphonate treatment in PVO patients with osteoporosis was associated with a significantly lower occurrence of subsequent vertebral fracture at adjacent vertebral bodies and lower occurrence of subsequent surgery. 相似文献2.

BACKGROUND AND CONTEXT
The impact of underlying liver disease on surgical outcomes has been recognized in a wide variety of surgical disciplines. However, less empiric data are available about the importance of liver disease in spinal surgery.PURPOSE
To measure the independent impact of underlying liver disease on 30-day outcomes following surgery for the degenerative cervical spine.STUDY DESIGN
Retrospective comparative study.PATIENT SAMPLE
A cohort of 21,207 patients undergoing elective surgery for degenerative disease of the cervical spine from the American College of Surgeons National Surgical Quality Improvement Program.OUTCOME MEASURES
Outcome measures included mortality, hospital length of stay, and postoperative complications within 30 days of surgery.METHODS
The NSQIP dataset was queried for patients undergoing surgery for degenerative disease of the cervical spine from 2006 to 2015. Assessment of underlying liver disease was based on aspartate aminotransferase-to-platelet ratio index and Model of End-Stage Liver Disease-Sodium scores, computed from preoperative laboratory data. The effect of liver disease on outcomes was assessed by bivariate and multivariate analyses, in comparison with 16 other preoperative and operative factors.RESULTS
Liver disease could be assessed in 21,207 patients based on preoperative laboratory values. Mild liver disease was identified in 2.2% of patients, and advanced liver disease was identified in 1.6% of patients. The 30-day mortality rates were 1.7% and 5.1% in mild and advanced liver diseases, respectively, compared with 0.6% in patients with healthy livers. The 30-day complication rates were 11.8% and 31.5% in these patients, respectively, compared with 8.8% in patients with healthy livers. In multivariate analysis, the presence of any liver disease (mild or advanced) was independently associated with an increased risk of mortality (OR=2.00, 95% CI=1.12–3.55, p=.019), morbidity (OR=1.35, 95% CI=1.07–1.70, p=.012), and length of hospital stay longer than 7 days (OR=1.73, 95% CI=1.40–2.13, p<.001), when compared with 18 other preoperative and operative factors. Liver disease was also independently associated with perioperative respiratory failure (OR=1.80, 95% CI=1.21–2.68, p=.004), bleeding requiring transfusion (OR=1.43, 95% CI=1.01–2.02, p=.044), wound disruption (OR=2.82, 95% CI=1.04–7.66, p=.042), and unplanned reoperation (OR=1.49, 95% CI=1.05–2.11, p=.025).Conclusions
Liver disease independently predicts poor perioperative outcome following surgery for degenerative disease of the cervical spine. Based on these findings, careful consideration of a patient's underlying liver function before surgery may prove valuable in surgical decision-making, preoperative patient counseling, and postoperative patient care. 相似文献3.

BACKGROUND CONTEXT
Surgical treatment of cervical ossification of the posterior longitudinal ligament (OPLL) has a high risk of various complications. Anterior decompression with fusion (ADF) and laminoplasty (LAMP) are the most representative surgical procedures. However, few studies have compared the two procedures in terms of perioperative surgical complications.PURPOSE
To compare the perioperative complications post-ADF and LAMP for cervical OPLL using a large national inpatient database.STUDY DESIGN
A retrospective cohort study with propensity score matching analysis.PATIENT SAMPLE
Overall, 8,718 (ADF/LAMP:1,333/7,485) patients who underwent surgery for cervical OPLL from April 1, 2010 to March 31, 2016 in hospitals using the diagnosis procedure combination were analyzed.OUTCOME MEASURES
The occurrence of postoperative complications during hospitalization.METHODS
We compared the perioperative systemic and local complications, reoperation rates, and costs between ADF and LAMP using propensity score matching analysis.RESULTS
One-to-one matching resulted in 1,192 pairs of patients who underwent ADF and LAMP. The postoperative cardiovascular event rate was significantly higher (ADF/LAMP=1.9/0.8%, p=.013) in the ADF group. The incidence rates of dysphagia (similarly, 2.4/0.2%, p<.001), pneumonia (1.0/0.3%, p=.045), and spinal fluid leakage (2.4/0.4%, p<.001) were also higher in the ADF group, even after matching. The costs were also higher in the ADF group. However, surgical site infection (2.0/3.4%, p=.033) was significantly lower in the ADF group. No significant difference in the reoperation rates was found between the groups.CONCLUSION
The present study, using a large nationwide database, demonstrated that perioperative complications were more common in the ADF group, but that surgical site infection (SSI) was more frequently observed in the LAMP group. 相似文献4.

BACKGROUND
In modern clinical research, the accepted minimum follow-up for patient-reported outcome measures (PROMs) after lumbar spine surgery is 24 months, particularly after fusion. Recently, this minimum requirement has been called into question.PURPOSE
We aim to quantify the concordance of 1- and 2-year PROMs to evaluate the importance of long-term follow-up after elective lumbar spine surgery.STUDY DESIGN
Retrospective analysis of data from a prospective registry.PATIENT SAMPLE
We identified all patients in our prospective institutional registry who underwent degenerative lumbar spine surgery with complete baseline, 12-month, and 24-month follow-up for ODI and numeric rating scales for back and leg pain (NRS-BP and NRS-LP).OUTCOME MEASURES
Oswestry Disability Index (ODI) and NRS-BP and NRS-LP at 1 year and at 2 years.METHODS
We evaluated concordance of 1- and 2-year change scores by means of Pearson's product-moment correlation and performed logistic regression to assess if achieving the minimum clinically important difference (MCID) at 12 months predicted 24-month MCID. Odds ratios (OR) and their 95% confidence intervals (CI), as well as model areas-under-the-curve were obtained.RESULTS
A total of 210 patients were included. We observed excellent correlation among 12- and 24-month ODI (r?=?0.88), NRS-LP (r?=?0.76) and NRS-BP (r?=?0.72, all p <.001). Equal results were obtained when stratifying for discectomy, decompression, or fusion. Patients achieving 12-month MCID were likely to achieve 24-month MCID for ODI (OR: 3.3, 95% CI: 2.4–4.1), NRS-LP (OR: 2.99, 95% CI: 2.2–4.2) and NRS-BP (OR: 3.4, 95% CI: 2.7–4.2, all p <.001) with excellent areas-under-the-curve values of 0.81, 0.77, and 0.84, respectively. Concordance rates between MCID at both follow-ups were 87.2%, 83.8%, and 84.2%. A post-hoc power analysis demonstrated sufficient statistical power.CONCLUSIONS
Irrespective of the surgical procedure, 12-month PROMs for functional disability and pain severity accurately reflect those at 24 months. In support of previous literature, our results suggest that 12 months of follow-up may be sufficient for evaluating spinal patient care in clinical practice as well as in research. 相似文献5.

BACKGROUND CONTEXT
Although 40% of adolescent idiopathic scoliosis (AIS) patients present with chronic back pain, the pathophysiology and underlying pain mechanisms remain poorly understood. We hypothesized that development of chronic pain syndrome in AIS is associated with alterations in pain modulatory mechanisms.PURPOSE
To identify the presence of sensitization in nociceptive pathways and to assess the efficacy of the diffuse noxious inhibitory control in patients with AIS presenting with chronic back pain.STUDY DESIGN
Cross-sectional study.PATIENT SAMPLE
Ninety-four patients diagnosed with AIS and chronic back pain.OUTCOME MEASURES
Quantitative sensory testing (QST) assessed pain modulation and self-reported questionnaires were used to assess pain burden and health-related quality of life.METHODS
Patients underwent a detailed pain assessment using a standard and validated quantitative sensory testing (QST) protocol. The measurements included mechanical detection thresholds (MDT), pain pressure threshold (PPT), heat pain threshold (HPT), heat tolerance threshold (HTT), and a conditioned pain modulation (CPM) paradigm. Altogether, these tests measured changes in regulation of the neurophysiology underlying the nociceptive processes based on the patient's pain perception. Funding was provided by The Louise and Alan Edwards Foundation and The Shriners Hospitals for Children.RESULTS
Efficient pain inhibitory response was observed in 51.1% of patients, while 21.3% and 27.7% had sub-optimal and inefficient CPM, respectively. Temporal summation of pain was observed in 11.7% of patients. Significant correlations were observed between deformity severity and pain pressure thresholds (p=.023) and CPM (p=.017), neuropathic pain scores and pain pressure thresholds (p=.015) and temporal summation of pain (p=.047), and heat temperature threshold and pain intensity (p=.048).CONCLUSIONS
Chronic back pain has an impact in the quality of life of adolescents with idiopathic scoliosis. We demonstrated a high prevalence of impaired pain modulation in this group. The association between deformity severity and somatosensory dysfunction may suggest that spinal deformity can be a trigger for abnormal neuroplastic changes in this population contributing to chronic pain syndrome. 相似文献6.

BACKGROUND CONTEXT
Spinal epidural lipomatosis (SEL) is a condition in which excess lumbar epidural fat (EF) deposition often leads to compression of the cauda equina or nerve root. Although SEL is often observed in obese adults, no systematic research investigating the potential association between SEL and metabolic syndrome has been conducted.PURPOSE
To elucidate potential association between SEL and metabolic syndrome.STUDY DESIGN
An observational study used data of a medical checkup.PATIENT SAMPLE
We retrospectively reviewed data from consecutive subjects undergoing medical checkups. A total of 324 subjects (174 men and 150 women) were enrolled in this study.OUTCOME MEASURES
The correlation of EF accumulation with demographic data and metabolic-related factors was evaluated.METHODS
The degree of EF accumulation was evaluated based on the axial views of lumbar magnetic resonance imaging. Visceral and subcutaneous fat areas were measured at the navel level using abdominal computed tomography. Metabolic syndrome was diagnosed according to the criteria of the Japanese Society of Internal Medicine. The correlation of SEL with metabolic syndrome and metabolic-related conditions was statistically evaluated.RESULTS
The degree of EF accumulation demonstrated a significant correlation to body mass index, abdominal circumference, and visceral fat area. However, age, body fat percentage, and subcutaneous fat area showed no correlation with the degree of EF accumulation. Logistic regression analysis revealed that metabolic syndrome (odds ratio [OR]=3.8, 95% confidence interval [CI]=1.5–9.6) was significantly associated with SEL. Among the diagnostic criteria for metabolic syndrome, visceral fat area ≥100 cm2 (OR=4.8, 95% CI=1.5–15.3) and hypertension (OR=3.5, 95% CI=1.1–11.8) were observed to be independently associated with SEL.CONCLUSION
This is the first study to demonstrate that metabolic syndrome is associated with SEL in a relatively large, unbiased population. Our data suggest that metabolic-related conditions are potentially related to EF deposition and that SEL could be a previously unrecognized manifestation of metabolic syndrome. 相似文献7.

BACKGROUND CONTEXT
Both open surgical resection (OSR) and radiofrequency ablation (RFA) have been reported for spinal osteoid osteoma (OO).PURPOSE
To verify the clinical safety and efficiency of RFA with OSR in treating spinal OO.STUDY DESIGN
Retrospective cohort study.PATIENT SAMPLE
Twenty-eight consecutive patients with spinal OO who underwent either RFA or OSR in our institute between September 2006 and December 2016.OUTCOME MEASURES
The age, gender, lesion distribution, surgical time, estimated blood loss, complications, local recurrence, visual analogue scale (VAS), and the modified Frankel grade were documented.METHODS
We retrospectively reviewed 28 patients with spinal OO who had been treated in our hospital from September 2006 to December 2016. Patients were followed at 3, 6, 12, and 24 months after the index surgery. The minimum follow-up period was 12 months. This study was funded by Peking University Third Hospital (Y71508-01) (¥ 400,000).RESULTS
Twelve and 16 patients were treated with CT-guided percutaneous RFA and OSR, respectively. Spinal OO locations were cervical in 4, thoracic in 4, lumbar in 3, and sacral vertebra in 1 in the RFA group and cervical in 12, thoracic in 1, and lumber in 3 in the OSR group. RFA showed shorter operating time, less blood loss, and less in-hospital stay than open surgery [105.0 ± 33.8 minutes vs. 186.4 ± 53.5 minutes (p < .001), 1 (0 to 5) ml vs. 125 (30–1200) ml (p < .001) and 1 (1–3) days vs. 6 (3–10) days (p < .001), respectively]. At last follow-up, one patient underwent a secondary RFA for recurrence. VAS improvement was 7.5 (3–10) and 6.5 (4–9) (p = .945) in the RFA and OSR groups, respectively. The overall complication rate was 8.3% (1/12) and 18.8% (3/16) in the RFA and OSR groups, respectively.CONCLUSIONS
If there is sufficient cerebrospinal fluid between the spinal OO lesion and spinal cord/nerve root (more than 1 mm), RFA is effective and safe for treatment of well-selected spinal OO, showing reduced operating time, blood loss, in-hospital stay, and complications compared to OSR. However, OSR is still recommended in cases with spinal cord/nerve root compression. 相似文献8.

BACKGROUND CONTEXT
Although facet dislocations account for only 6% of cervical trauma, the consequences are often devastating. Cervical facet dislocations are associated with a disproportionate amount of spinal cord injuries; however, neurologic examination of patients is often difficult, as patients commonly present with reduced levels of consciousness. There are limited studies that have investigated the impact of spinal canal diameter and translation on neurologic injury following facet dislocations.PURPOSE
Review a consecutive series of patients with facet dislocations to assess the impact of sagittal diameter and translation on Spinal Cord Injury (SCI).STUDY DESIGN
Retrospective review at a level I trauma center identified 97 patients with facet dislocations.METHODS
Between 2004 and 2014, a retrospective review at a level I trauma center identified patients with traumatic facet dislocation. Demographic data, neurologic exams, and radiographic findings were reviewed. We assessed sagittal diameter at the injury level, as well as above and below, and translation. This study has no funding source and its authors have no potential conflicts of interest-associated biases.RESULTS
Ninety-seven patients presented with facet dislocations. Fifty-nine (61%) presented with a SCI. Those with ASIA A averaged 8.0 mm of injury level canal diameter, and ASIA E averaged 12.6 mm (p < .001). Additionally, those with ASIA A averaged 8.0 mm of translation, and ASIA E averaged 4.2 mm (p < 0.001). Two groups were created based on their general motor function. Those with ASIA A–C averaged 8.4 mm of injury level canal diameter, and ASIA D–E averaged 12.3 mm (p < .001). Those with ASIA A–C averaged 7.8 mm of translation, and ASIA D–E averaged 4.4 mm (p < .001). Receiver operating characteristic (ROC) curves demonstrated that translation was a good predictor of ASIA A–C and canal diameter was an almost perfect predictor of ASIA D–E.CONCLUSIONS
Our data indicate that patients with greater translation and/or a smaller canal diameter at the injury level have a higher rate of SCI. Adjacent canal diameter did not correlate with neurologic injury. 相似文献9.

BACKGROUND CONTEXT
Lumbar spinal stenosis (LSS) can impair blood flow to the spinal nerves giving rise to neurogenic claudication and limited walking ability. Reducing lumbar lordosis can increases the volume of the spinal canal and reduce neuroischemia. We developed a prototype LSS belt aimed at reducing lumbar lordosis while walking.PURPOSE
The aim of this study was to assess the short-term effectiveness of a prototype LSS belt compared to a lumbar support in improving walking ability in patients with degenerative LSS.STUDY DESIGN
This was a two-arm, double-blinded (participant and assessor) randomized controlled trial.PATIENT SAMPLE
We recruited 104 participants aged 50 years or older with neurogenic claudication, imaging confirmed degenerative LSS, and limited walking ability.OUTCOME MEASURES
The primary measure was walking distance measured by the self-paced walking test (SPWT) and the primary outcome was the difference in proportions among participants in both groups who achieved at least a 30% improvement in walking distance from baseline using relative risk with 95% confidence intervals.METHODS
Within 1 week of a baseline SPWT, participants randomized to the prototype LSS belt group (n=52) and those randomized to the lumbar support group (n=52) performed a SPWT that was conducted by a blinded assessor. The Arthritis Society funded this study ($365,000 CAN) with salary support for principal investigator funded by the Canadian Chiropractic Research Foundation ($500,000 CAN for 5 years).RESULTS
Both groups showed significant improvement in walking distance, but there was no significant difference between groups. The mean group difference in walking distance was ?74 m (95% CI: ?282.8 to 134.8, p=.49). In total, 62% of participants wearing the prototype LSS belt and 82% of participants wearing the lumbar support achieved at least 30% improvement in walking distance (relative risk, 0.7; 95% CI: 0.5–1.3, p=.43).CONCLUSIONS
A prototype LSS belt demonstrated significant improvement in walking ability in degenerative LSS but was no better than a lumbar support. 相似文献10.

Background
The essence of enhanced recovery after surgery (ERAS) program is the multimodal approach, and many authors have demonstrated safety and feasibility in fast-track bariatric surgery.Objectives
The aim of this study was to evaluate the postoperative pain after the implementation of an ERAS protocol in Roux-en-Y gastric bypass and to compare it with the application of a standard care protocol.Setting
University Hospital Rey Juan Carlos, Madrid, Spain.Methods
A prospective randomized clinical trial of all the patients undergoing Roux-en-Y gastric bypass was performed. Patients were randomized into the following 2 groups: those patients after an ERAS program and those patients after a standard care protocol. Postoperative pain, nausea or vomiting, morbidity, mortality, hospital stay, and analytic acute phase reactants 24 hours after surgery were evaluated.Results
One hundred eighty patients were included in the study, 90 in each group. Postoperative pain (16 versus 37 mm; P < .001), nausea or vomiting (8.9% versus 2.2%; P?=?.0498), and hospital stay (1.7 versus 2.8 d; P < .001) were significantly lower in the ERAS group. There were no significant differences in complications, mortality, and readmission rates. White blood cell count, serum fibrinogen, and C reactive protein levels were significantly lower in the ERAS group 24 hours after surgery.Conclusion
The implementation of an ERAS protocol was associated with lower postoperative pain, reduced incidence of postoperative nausea or vomiting, lower levels of acute phase reactants, and earlier hospital discharge. Complications, reinterventions, mortality, and readmission rates were similar to that obtained after a standard care protocol. 相似文献11.

BACKGROUND CONTEXT
Pedicle screw loosening is common after spinal fusion and can be associated with pseudoarthrosis and pain. With suspicion of screw loosening on standard radiographs, CT is currently considered the advanced imaging modality of choice. MRI with new metal artifact reduction techniques holds potential to be sensitive in detection of screw loosening. The sensitivity and specificity of either of the imaging modalities are yet clear.PURPOSE
To evaluate the sensitivity and specificity of three different image modalities (standard radiographs, CT, and MRI) for detection of pedicle screw loosening.STUDY DESIGN/SETTING
Cross-sectional diagnostic study.PATIENT SAMPLE
Forty-one patients (159 pedicle screws) undergoing revision surgeries after lumbar spinal fusion between August 2014 and April 2017 with preoperative radiographs, CT, and MRI with spinal metal artifact reduction (STIR WARP and TSE high bandwidth sequences).OUTCOME MEASURES
Sensitivity and specificity in detection of screw loosening for each imaging modality.METHODS
Screw torque force was measured intraoperatively and compared with preoperative screw loosening signs such as peri-screw edema in MRI and peri-screw osteolysis in CT and radiographs. A torque force of less than 60 Ncm was used to define a screw as loosened.RESULTS
Sensitivity and specificity in detection of screw loosening was 43.9% and 92.1% for MRI, 64.8% and 96.7% for CT, and 54.2% and 83.5% for standard radiographs, respectively.CONCLUSIONS
Despite improvement of MRI with metal artifact reduction MRI technique, CT remains the modality of choice. Even so, CT fails to detect all loosened pedicle screws. 相似文献12.
BACKGROUND
The pattern of linear graph schematized by visual analogue scale (VAS) score displaying pain worsening between 2 days and 2 weeks after selective nerve root block (SNRB) is called rebound pain.PURPOSE
The purpose of this study was to determine if sodium hyaluronate and carboxymethyl cellulose solution (HA-CMC sol) injection could reduce the occurrence of rebound pain at 3 days to 2 weeks after SNRB in patients with radiculopathy compared with injection with corticosteroids and local anesthetics alone.STUDY DESIGN/SETTING
Double blinded randomized controlled clinical trial.PATIENT SAMPLE
A total of 44 patients (23 of 24 patients in the Guardix group and 21 of 24 patients in the control group) who finished the follow-up session were subjects of this study.OUTCOME MEASUREMENT
Patients were asked to write down their average VAS pain scores daily for 12 weeks. Functional outcomes were assessed by Oswestry Disability Index, Roland Morris Disability Questionnaire , and Short Form-36.METHOD
A cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of normal saline was used for the control group whereas a cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of HA-CMC solution was used for the G group. Study participants were randomized into one of two treatment regimens. They were followed up for 3 months.RESULTS
VAS score at 2 weeks after the procedure was 4.19±1.32 in the control group, which was significantly (p<.05) higher than that (2.43±1.24) in the G group. VAS score at 6 weeks after the procedure was 4.00±1.23 in the control group and 3.22±1.45 in the G group, showing no significant (p=.077) difference between the two groups. There were no significant differences in functional outcomes at 6 or 12 weeks after the procedure.CONCLUSIONS
Compared with conventional cocktail used for SNRB, addition of HA-CMC sol showed effective control of rebound pain at 3 days to 2 weeks after the procedure. 相似文献13.
Selective blocking laminoplasty in cervical laminectomy and fusion to prevent postoperative C5 palsy
BACKGROUND CONTEXT
Cervical laminectomy and fusion (CLF) is a common surgical option for multilevel cord compression. Postoperative C5 palsy occurrence after CLF has been a vexing problem for spine physicians. The posterior shift of the cord following laminectomy has been implicated as a major factor for postoperative C5 palsy, but attempts by spine surgeons to mitigate excessive shift while providing sufficient decompression have not been well reported.PURPOSE
To compare the incidence of postoperative C5 palsy after performing selective blocking laminoplasty concurrently with CLF to those of conventional CLF.STUDY DESIGN
A retrospective comparative study of prospectively collected data.PATIENT SAMPLE
Of 116 cervical myelopathy patients with degenerative cervical myelopathy, ossification of the posterior longitudinal ligament, and multilevel disc herniation, 93 patients (69 in group A [CLF group] and 24 in group B [selective blocking laminoplasty with CLF, CLF-S group]) were included in the study.OUTCOME MEASURES
The primary outcome measure was the occurrence of postoperative C5 palsy. Secondary end points included (1) clinical outcomes based on pain intensity, neck disability index (NDI), Japanese Orthopaedic Association (JOA) score, (2) radiologic outcomes including cervical alignment and fusion rate at 1 year and hardware complications, and (3) perioperative data (hospital stay, blood loss, and operative times).METHODS
We compared the occurrence of postoperative C5 palsy, as well as clinical, radiologic, and surgical outcomes, between the two groups at 1-year follow-up.RESULTS
The patients in both groups were statistically similar between the groups with respect to demographic characteristics such as age, sex, smoking status, body mass index, preoperative pathology, surgical segments, and the degree of the cervical lordosis. Postoperative C5 palsy developed in 9 of 61 patients (14%) in group A and in 0 of 24 patients (0%) in group B (CLF-S group) (p=.03). Postoperative neck pain, NDI, and JOA improvement were not significantly different between the two groups (p=.93, 0.90, and 0.79, respectively). Perioperative data did not differ significantly between the two groups.CONCLUSIONS
This study showed that performing selective blocking laminoplasty might lead to reducing the incidence of postoperative C5 palsy in CLF surgery. 相似文献14.

BACKGROUND CONTEXT
Anterior cervical discectomy and fusion (ACDF) without and with cervical plating (ACDF+CP) are accepted surgical techniques for the treatment of degenerative cervical disc disorders. The effect of CP on the development of adjacent segment degeneration (ASD) remains unclear.PURPOSE
To assess whether CP accelerates the degeneration of the adjacent and adjoining segments.STUDY DESIGN/SETTING
This is an imaging cohort study.PATIENT SAMPLE
Retrospectively, a total of 84 patients who underwent ACDF or ACDF+CP were identified. At final follow-up, an MRI was performed and evaluated in this study.MATERIALS AND METHODS
An MRI of 84 patients who underwent ACDF (46 patients) and ACDF+PS (38 patients) was performed. The mean follow-up was 24 years (17–45 years). None of the patients had a repeat procedure in the cervical spine. The grade of degeneration of the segments adjacent and adjoining to the fusion was assessed via a five-step grading system (segmental degeneration index, or SDI) that includes disc signal intensity, anterior and posterior disc protrusion, narrowing of the disc space, and foraminal stenosis. Furthermore, the disc height (DH) and sagittal segmental angle (SSA) of fused segments were measured.RESULTS
A significantly (p<.001) greater SDI was identified at the caudal adjacent segment following ACDF compared to ACDF+CP. No other significant differences were identified in patients following ACDF and ACDF+CP. Between 50% and 96% of all segments showed severe degenerative changes according to SDI. There was no significant difference in DH between the patients following ACDF and ACDF+CP. The SSA in patients who underwent ACDF+CP was significantly greater than in the ACDF patients (p=.002).CONCLUSIONS
In this cohort of patients, cervical plating had no significant impact on segmental degeneration and decrease of DH in the adjacent and adjoining segments. ACDF+CP seem to preserve the lordotic alignment more with respect to the SSA than ACDF. 相似文献15.

BACKGROUND CONTEXT
Data on the long-term outcome after fusion for isthmic spondylolisthesis are scarce.PURPOSE
To study patient-reported outcomes and adjacent segment degeneration (ASD) after fusion for isthmic spondylolisthesis and to compare patient-reported outcomes with a control group.STUDY DESIGN/SETTING
A prospective study including a cross-sectional control group.PATIENT SAMPLE
Patients with isthmic spondylolisthesis underwent posterior lumbar interbody fusion (PLIF) (n=86) or posterolateral fusion (PLF) (n=77). Patient-reported outcome data were available for 73 patients in the PLIF group and 71 in the PLF group at a mean of 11 (range 5–16) years after baseline. Seventy-seven patients in the PLIF group and 54 in the PLF group had radiographs at a mean of 14 (range 9–19) years after baseline. One hundred thirty-six randomly selected persons from the population served as controls for the patient-reported outcomes.OUTCOME MEASURES
Patient-reported outcomes include the following: global outcome, Oswestry Disability Index, Disability Rating Index, and Short Form 36. The ASD was determined from radiographs using the University of California Los Angeles (UCLA) grading scale.METHODS
: The chi-square test or analysis of covariance (ANCOVA) was used for group comparisons. The ANCOVA was adjusted for follow-up time, smoking, Meyerding slippage grade, teetotaler (yes/no) and, if available, the baseline level of the dependent variable.RESULTS
There were no significant patient-reported outcome differences between the PLIF group and the PLF group. The prevalence of ASD was 42% (32/77) in the PLIF group and 26% (14/54) in the PLF group (p=.98). The patient-reported outcome data indicated lower physical function and more pain in individuals with surgically treated isthmic spondylolisthesis compared to the controls.CONCLUSIONS
PLIF and PLF groups had similar long-term patient-reported and radiological outcomes. Individuals with isthmic spondylolisthesis have lower physical function and more pain several years after surgery when compared to the general population. 相似文献16.

BACKGOUND CONTEXT
Abnormal proximal femoral angle (PFA) was recently found to be associated with deteriorating sagittal balance and quality of life (QoL) in high-grade spondylolisthesis (HGS). However, the influence of PFA on the QoL of patients undergoing surgery remains unknown.PURPOSE
This study compares the pre- and postoperative measurements of sagittal balance including PFA in patients with lumbosacral HGS after surgery. It also determines if PFA is a radiographic parameter that is associated with QoL in patients undergoing surgery.STUDY DESIGN
Retrospective cohort study.PATIENT SAMPLE
Thirty-three patients (mean age 15.6 ± 3.0 years) operated for L5-S1 HGS between July 2002 and April 2015. Thirteen had in situ fusion and 20 had reduction to a low-grade slip.OUTCOME MEASURES
The outcome measures included PFA and QoL scores measured from the Scoliosis Research Society SRS-30 QoL questionnaire.METHODS
The minimum follow-up was 2 years. PFA and QoL were compared pre- and postoperatively. Statistical analysis used nonparametric Mann-Whitney and Wilcoxon Signed Rank tests, Chi-square tests to compare proportions, and bivariate correlations with Spearman's coefficients.RESULTS
A decreasing PFA correlated with less pain (r = ?0.56, p?=?.010), improved function (r = ?0.51, p?=?.022) and better self-image (r = ?0.46, p?=?.044) postreduction. Reduction decreased PFA by 5.1° (p?=?.002), whereas in situ fusion did not alter PFA significantly. Patients with normal preoperative PFA had similar postoperative QoL regardless of the type of surgery, except for self-image, which improved further with reduction (3.73 ± 0.49 to 4.26 ± 0.58, p?=?.015). Patients with abnormal preoperative PFA tended to have a higher QoL in all domains after reduction.CONCLUSION
Decreasing PFA correlates with less pain, better function and self-image. Reduction of HGS decreases PFA. Reduction also relates to a better postoperative QoL when the preoperative PFA is abnormal. When the preoperative PFA is normal, in situ fusion is equivalent to reduction except for self-image, which is better improved after reduction. 相似文献17.

Background
Recently, sleeve gastrectomy (SG) has become one of the most important procedures in bariatric surgery. Short-term results show that SG is a feasible, safe, and effective operation treating obesity and its related co-morbidities. Now, the main focus is on long-term data after SG.Objectives
The aim of this study was to analyze perioperative and long-term results after SG in the German Bariatric Surgery Registry.Setting
National database, Germany.Methods
Perioperative data of primary SG (n?=?21525) and follow-up data for 5 years ± 6 months (n?=?435, 18.3% of 2375 SG performed between 2005 and 2011) were analyzed. After a review of the literature long-term results were compared with international data.Results
Mean baseline body mass index (BMI) was 51.1 kg/m2. Two hundred ninety-eight (68.5%) patients were female and 137 (31.5%) were male. Of patients, 90% had ≥1 co-morbidities. Mean operation time was 86 minutes. General postoperative complications occurred in 4.1% and special complications in 4.6% (staple-line leaks 1.6%). Mean maximum BMI loss was 18.0 ± 6.8 kg/m2 and BMI loss after 5 years was 14.3 ± 7.4 kg/m2 (P < .001). Co-morbidities, such as type 2 diabetes, hypertension, and sleep apnea, were significantly improved (P < .001). Gastroesophageal reflux was significantly impaired (P < .001).Conclusions
The current results showed that SG is a safe and effective procedure in bariatric surgery. BMI loss was significant 5 years after SG. Most co-morbidities were significantly improved, but gastroesophageal reflux has often worsened. The follow-up rate was very low, which is a persistent problem in German bariatric surgery. 相似文献18.

Background
Bariatric surgery is an effective and durable treatment for obesity. However, the number of patients that progress to bariatric surgery after initial evaluation remains low.Objectives
The purpose of this study was to identify factors influencing a qualified patient's successful progression to surgery in a U.S. metropolitan area.Setting
Academic, university hospital.Methods
A single-institution retrospective chart review was performed from 2003 to 2016. Patient demographics and follow-up data were compared between those who did and did not progress to surgery. A follow-up telephone survey was performed for patients who failed to progress. Univariate analyses were performed and statistically significant variables of interest were analyzed using a multivariable logistic regression model.Results
A total of 1102 patients were identified as eligible bariatric surgery candidates. Four hundred ninety-eight (45%) patients progressed to surgery and 604 (55%) did not. Multivariable analysis showed that patients who did not progress were more likely male (odds ratio [OR] 2.2 confidence interval [CI]: 1.2–4.2, P < .05), smokers (OR 2.4 CI: 1.1–5.4, P < .05), attended more nutrition appointments (OR 2.1 CI: 1.5–2.8, P < .0001), attended less total preoperative appointments (OR .41 CI: .31–.55, P < .0001), and resided in-state compared with out of state (OR .39 CI: .22–.68, P < .05). The top 3 patient self-reported factors influencing nonprogression were fear of complication, financial hardship, and insurance coverage.Conclusions
Multiple patient factors and the self-reported factors of fear of complication and financial hardship influenced progression to bariatric surgery in a U.S. metropolitan population. Bariatric surgeons and centers should consider and address these factors when assessing patients. 相似文献19.

BACKGROUND CONTEXT
Postdischarge care is a significant source of cost variability after posterior lumbar fusion surgery. However, there remains limited evidence associating postdischarge inpatient services and improved postoperative outcomes, despite the high cost of these services.PURPOSE
To determine the association between posthospital discharge to inpatient care facilities and postoperative complications.STUDY DESIGN
A retrospective review of all 1- to 3-level primary posterior lumbar fusion cases in the 2010-2014 National Surgical Quality Improvement Program registry was conducted. Propensity scores for discharge destination were determined based on observable baseline patient characteristics. Multivariable propensity-adjusted logistic regressions were performed to determine associations between discharge destination and postdischarge complications, with adjusted odds ratios (OR) and 95% confidence intervals (CI).RESULTS
A total of 18,652 posterior lumbar fusion cases were identified, 15,234 (82%) were discharged home, and 3,418 (18%) were discharged to continued inpatient care. Multivariable propensity-adjusted analysis demonstrated that being discharged to inpatient facilities was independently associated with higher risk of thromboembolic complications (OR [95% CI]: 1.79 [1.13–2.85]), urinary complications, (1.79 [1.27–2.51]), and unplanned readmissions (1.43 [1.22–1.68]).CONCLUSIONS
Discharge to continued inpatient care versus home after primary posterior lumbar fusion is independently associated with higher odds of certain major complications. To optimize clinical outcomes as well as cost savings in an era of value-based reimbursements, clinicians and hospitals should consider further investigation into carefully investigating which patients might be better served by home discharge after surgery. 相似文献20.
