- Study Design.Comparative cohort study. Objective.The aim of the present study was to evaluate pain and health-related quality of life (HRQoL) in surgically managed patients with a minimum follow-up of 10 years compared with patients with untreated adolescent idiopathic scoliosis (AIS) and a healthy control group. Summary of Background Data.Posterior spinal fusion with pedicle screws is the standard treatment for AIS, although it remains unclear whether this procedure results in improved long-term HRQoL compared with untreated patients with AIS. Patients and Methods.Sixty-four consecutive patients at a minimum follow-up of 10 years, who underwent posterior pedicle screw instrumentation for AIS were prospectively enrolled. Fifty-three (83%) of these patients completed Scoliosis Research Society (SRS) 24 questionnaires, clinical examination, and standing spinal radiographs. Pain and HRQoL were compared with age and sex-matched patients with untreated AIS and healthy individuals. Results.The mean major curve was 57 degrees preoperatively and 15 degrees at the 10-year follow-up. SRS-24 self-image domain score showed a significant improvement from preoperative to 2 years and remained significantly better at the 10-year follow-up (P < 0.001). Patients fused to L3 or below had lower pain, satisfaction, and total score than patients fused to L2 or above (P < 0.05), but self-image, function, and activity scores did not differ between groups at 10-year follow-up. Pain, self-image, general activity, and total SRS domains were significantly better at 10-year follow-up in the surgically treated patients as compared with untreated patients (all P < 0.05). Healthy controls had significantly higher total scores than those surgically treated at 10-year follow-ups (P < 0.001). Conclusion.Patients undergoing segmental pedicle screw instrumentation for AIS maintain high-level HRQoL during a 10-year follow-up. Their HRQoL was significantly better than in the untreated patients with AIS, except for the function domain. However, HRQoL remained at a lower level than in healthy controls.

- STUDY DESIGN: Four-year prospective cohort study. OBJECTIVE: To find the incidence of sick leave because of neck and shoulder pain (NSP) in industrial workers, and its association with work and lifestyle risk factors. SUMMARY OF BACKGROUND DATA: Longitudinal studies to investigate NSP incidence and risk factors are rare, and even fewer have been conducted in middle- and low-income countries. METHODS: After inviting all full-time employees of an Iranian car manufacturing company with 18,031 employees to participate in a baseline study, they were followed for 4 years. New episodes of sick leave because of NSP have been calculated based on sickness absence registration between the years 2003 and 2007. The incidence was compared for participants and nonparticipants. The association between sick leave, physical, and psychosocial risk factors at work, and previous self-reported NSP, was calculated for the remaining population of baseline participants (12,184 employees) during a 4-year follow-up. RESULTS: During a 4-year follow-up of study subjects for the remaining participants of the baseline study, the incidence of sick leave was 0.8% (98 sick leave cases in 12,184 employees). For nonparticipants this incidence was 4.2% (130 cases in 3127 employees). In the final regression model for sick leave cases, the remaining factors for potential physical risk factors were repetitive work and sitting positions at work; for psychosocial factors unattractive work was the only significant remaining factor. CONCLUSION: The incidence of NSP based on sick leave is definitely very low compared with previous studies in high-income countries. This incidence varies between participants and nonparticipants. Risk factors for sick leave differ from risk factors for self-reported pain. A young population, job security, the insurance system, different health behaviors, and healthy worker bias, are all factors that may affect the results, and sick-leave as an outcome must be interpreted with more caution in middle- and low-income countries.

- STUDY DESIGN: Retrospective cohort study.OBJECTIVE: To validate the precision of four predictive scoring systems for spinal metastatic disease and evaluate whether they underestimate or overestimate survival.SUMMARY OF BACKGROUND DATA: Metastatic spine disease is a common complication to malignancies. Several scoring systems are available to predict survival and to help the clinician to select surgical or nonsurgical treatment.METHODS: Three hundred fifteen adult patients (213 men, 102 women, mean age 67 yr) undergoing spinal surgery at Uppsala University Hospital, Sweden, due to metastatic spine disease 2006 to 2012 were included. Data were collected prospectively for the Swedish Spine Register and retrospectively from the medical records. Tokuhashi scores, Revised Tokuhashi Scores, Tomita scores, and Modified Bauer Scores were calculated and compared with actual survival data from the Swedish Population Register.RESULTS: The mean estimated survival time after surgery for all patients included was 12.4 months (confidence interval 10.6-14.2) and median 5.9 months (confidence interval 4.5-7.3). All four scores had significant correlation to survival (P < 0.0001) but tended to underestimate rather than overestimate survival. Modified Bauer Score was the best of the four scores to predict short survival, both regarding median and mean survival. Tokuhashi score was found to be the best of the scores to predict long survival, even though the predictions were inaccurate in 42% of the cases.CONCLUSION: Predictive scores underestimate survival for the patients which might affect important clinical decisions.LEVEL OF EVIDENCE: 3.

- Study Design. Observational cohort study. Objective. The aim of this study was to investigate whether preservation of the midline structures is associated with a better clinical outcome compared to classic central decompression for lumbar spinal stenosis (LSS). Summary of Background Data. The classic surgical procedure for LSS is a central, facet joint sparing decompressive laminectomy (LE). Alternative approaches have been developed to preserve the midline structures. The effect of the alternative techniques compared to LE remains unclear. Methods. All patients >50 years of age who underwent decompression surgery for LSS without concomitant fusion in the National Swedish Spine Registry (Swespine) from December 31, 2015 until October 6, 2017 were included in this study based on surgeon-reported data and patient questionnaires before and 2 years postoperatively. Propensity score matching was used to compare decompression with preservation of midline structures with patients who underwent LE. The primary outcome was the Oswestry Disability Index (ODI) and secondary outcomes were the Numeric Rating Scale (NRS) for leg and back pain, EuroQol-5 Dimensions (EQ-5D), Global Assessment (GA), patient satisfaction and rate of subsequent surgery. Results. Some 3339 patients completed a 2-year follow-up. Of these, 2974 (89%) had decompression with LE and 365 underwent midline preserving surgery. Baseline scores were comparable between the groups. Mean ODI improvement at follow-up was 16.6 (SD = 20.0) in the LE group and 16.9 (SD = 20.2) in the midline preserving surgery group. In the propensity score-matched analysis the difference in improved ODI was 0.53 (95% confidence interval, CI -1.71 to 2.76; P = 0.64). The proportion of patients who showed a decreased ODI score of at least our defined minimal clinically important difference (=8) was 68.3% after LE and 67.0% after preserving the midline structures (P = 0.73). No significant differences were found in the improvement of NRS for leg and back pain, EQ-5D, GA or patient satisfaction. The rate of subsequent surgery was 5.5% after LE and 4.9% after midline preserving surgery without a significant difference in the propensity score-matched analysis (hazard ratio, HR 0.87; 95% CI 0.49-1.54; P = 0.64). Conclusion. In this study on decompression techniques for LSS, there was no benefit in preserving the midline structures compared to LE 2 years after decompression. The conclusion is that the surgeon is free to choose the surgical method that is thought most suitable for the patient and the condition with which the patient presents.

- Study Design. Prospective randomized controlled trial. Objective. To analyze factors that may influence the outcome of anterior cervical decompression and fusion (ACDF) followed by physiotherapy versus physiotherapy alone for treatment of patients with cervical radiculopathy. Summary of Background Data. An understanding of patient-related factors affecting the outcome of ACDF is important for preoperative patient selection. No previous prospective, randomized study of treatment effect modifiers relating to outcome of ACDF compared with physiotherapy has been carried out. Methods. 60 patients with cervical radiculopathy were randomized to ACDF followed by physiotherapy or physiotherapy alone. Data for possible modifiers of treatment outcome at 1 year, such as sex, age, duration of pain, pain intensity, disability (Neck Disability Index, NDI), patient expectations of treatment, anxiety due to neck/arm pain, distress (Distress and Risk Assessment Method), self-efficacy (Self-Efficacy Scale) health status (EQ-5D), and magnetic resonance imaging findings were collected. A multivariate analysis was performed to find treatment effect modifiers affecting the outcome regarding arm/neck pain intensity and NDI. Results. Factors that significantly altered the treatment effect between treatment groups in favor of surgery were: duration of neck pain less than 12 months (P = 0.007), duration of arm pain less than 12 months (P = 0.01) and female sex (P = 0.007) (outcome: arm pain), low EQ-5D index (outcome: neck pain, P = 0.02), high levels of anxiety due to neck/arm pain (outcome: neck pain, P = 0.02 and NDI, P = 0.02), low Self-Efficacy Scale score (P = 0.05), and high Distress and Risk Assessment Method score (P = 0.04) (outcome: NDI). No factors were found to be associated with better outcome with physiotherapy alone. Conclusion. In this prospective, randomized study of patients with cervical radiculopathy, short duration of pain, female sex, low health quality, high levels of anxiety due to neck/arm pain, low self-efficacy, and a high level of distress before treatment were associated with better outcome from surgery. No factors were found to be associated with better outcome from physiotherapy alone.

- STUDY DESIGN.: Prospective randomized controlled trial. OBJECTIVE.: To study the outcome of anterior cervical decompression and fusion combined with a structured physiotherapy program compared with the same physiotherapy program alone for patients with cervical radiculopathy. SUMMARY OF BACKGROUND DATA.: Knowledge concerning the effects of interventions for patients with cervical radiculopathy is scarce due to a lack of randomized studies. METHODS.: Sixty-three patients were randomized to surgery with postoperative physiotherapy (n = 31) or physiotherapy alone (n = 32). The surgical group was treated with anterior cervical decompression and fusion. The physiotherapy program included general/specific exercises and pain-coping strategies. The outcome measures were disability (Neck Disability Index), neck and arm pain intensity (visual analogue scale), and the patient's global assessment. Patients were followed for 24 months. RESULTS.: The result from the repeated-measures analysis of variance showed no significant between-group difference for Neck Disability Index (P = 0.23). For neck pain intensity, the repeated-measures analysis of variance showed a significant between-group difference during the study period in favor of the surgical group (P = 0.039). For arm pain intensity, no significant between-group differences were found according to the repeated-measures analysis of variance (P = 0.580). Eighty-seven percent of the patients in the surgical group rated their symptoms as "better/much better" at the 12-month follow-up compared with 62% in the nonsurgical group (P < 0.05). At 24 months, the corresponding figures were 81% and 69% (P = 0.28). The difference was significant only at the 12-month follow-up in favor of the surgical group. Significant reduction in Neck Disability Index, neck pain, and arm pain compared with baseline was seen in both groups (P < 0.001). CONCLUSION.: In this prospective, randomized study of patients with cervical radiculopathy, it was shown that surgery with physiotherapy resulted in a more rapid improvement during the first postoperative year, with significantly greater improvement in neck pain and the patient's global assessment than physiotherapy alone, but the differences between the groups decreased after 2 years. Structured physiotherapy should be tried before surgery is chosen. Copyright © 2013 Lippincott Williams & Wilkins. Unauthorized reproduction of this article is prohibited.

- Study Design: Retrospective study design on prospectively collected registry data.Objective: To investigate whether improvement after surgery for degenerative cervical myelopathy is associated with preoperative disease severity and to identify predictors of outcome.Summary of Background Data: Degenerative cervical myelopathy is the most common cause of spinal cord compromise in adults and surgery is often the treatment of choice. Identifying predictors may help to improve patient selection.Materials and Methods: This nationwide study from the Swedish spine registry included 901 patients treated surgically for degenerative cervical myelopathy. To investigate improvement in different disease severity groups, the individuals were divided into quartiles based on their preoperative European Myelopathy Scale (EMS) and EuroQol-5 Dimension (EQ-5D) index. Statistical analyses were made with analysis of variance, χ2, McNemar, and t tests. Multivariable linear or logistic regression was used to identify predictors for one-year improvement in EMS and EQ-5D index, and satisfaction at one year. In the regressions, the patient-reported outcome measures were dichotomized at their median, except improvement in EMS.Results: All patient-reported outcome measures improved from baseline to the one-year follow-up (P<0.001). Statistically significant outcome improvements were seen in all disease severity groups. Preoperative low EMS (β=−1.37, P<0.001), long walking distance (<500 vs. >500 m; β=0.44, P=0.030), and low NDI (β=−0.43, P=0.048) were independent predictors of improvement in EMS. R2 was 0.11 for the multivariable model. Preoperative low EQ-5D index (odds ratio=0.11; 95% confidence interval: 0.07–0.16) and low NDI (0.56; 0.36–0.88) were independent predictors of improvement in EQ-5D index. Preoperative high EMS (1.86; 1.20–2.90) and shorter arm pain duration [<12 vs. >12 months (0.54; 0.33–0.88)] were independent predictors of satisfaction.Conclusions: Postoperative improvement was seen over the whole range of disease severity. Disease severity, symptom duration, and walking distance were predictors of outcome in patients treated surgically for degenerative cervical myelopathy.

- Study design A 2-year follow-up of a randomized controlled trial. Objective To compare long-term effects of a) a multi-component pain and stress self-management group intervention (PASS) and b) individually administered physical therapy (IAPT) on patients with persistent tension-type neck pain in a primary health care (PHC) setting. Summary of Background Data In a previously reported short-term follow-up, PASS had better effects on pain control, pain-related self-efficacy, disability and catastrophizing than IAPT. Long-term effects of self-management interventions for persistent neck pain, e.g. maintenance of improvement and adherence to coping skills are sparsely investigated. Methods Persons with persistent tension-type neck pain seeking physical therapy treatment at nine PHC centers in Sweden were randomly assigned to either PASS or IAPT. Before intervention, at 10 and 20 weeks and at 1 and 2 years after the intervention, the participants completed a self-assessment questionnaire comprising: the Self-Efficacy Scale, the Neck Disability Index, the Coping Strategies Questionnaire, the Hospital Anxiety and Depression Scale and questions regarding neck pain and analgesics. Analyses were performed using linear mixed models for repeated measures. Results The study included 156 participants (PASS n=77, IAPT n=79). Between baseline, 10-week, 20-week, 1-year and 2-year follow-up, significant time by group interaction effects were found in favor of PASS regarding the primary outcomes ability to control pain (p<0.001) and self-efficacy for performing activities in spite of pain (p=0.002), and the secondary outcome catastrophic thinking (p<0.001) but not in neck pain related disability. Conclusions The initial treatment effects of a self-management group intervention were largely maintained over a 2 year follow-up period and with a tendency to have superior long-term effects as compared to individually administered physical therapy, in the treatment of persistent tension-type neck pain with regard to coping with pain, in terms of pain control, self-efficacy and catastrophizing.
