Abstract
Objectives A clinical disorder known as degenerative lumbar spine disease (DLSD) is characterized by persistent low back pain (LBP) coupled with radiculopathy and other signs of neurologic impairment. Using patient-reported pain outcome assessment tools, this study evaluated the pain outcome of non-instrumented lumbar decompressive surgery for DLSD. Materials and Methods A prospective longitudinal research was conducted. Using the metric visual analog scale (VAS) score and the Oswestry disability index (ODI), consenting patients who underwent non-instrumented lumbar decompressive surgery for symptomatic DLSD were evaluated for radicular pain and LBP. The evaluation was conducted both immediately before surgery and 6 months after surgery. Data generated by comparing the pre-operative and post-operative VAS and ODI scores were then analyzed using descriptive and inferential statistics. Results Sixty-seven patients in total completed the study. Thirty-six (54%) males and 31 (46%) females, with a mean age and body mass index of 55.28 years and 29.5 k/m2, respectively. At 6 months postoperatively, there was significant pain reduction from the pre-operative baseline VAS for LBP (67.12-32.74) with P < 0.001, VAS for radicular pain (75.39-32.75) with P < 0.001, and ODI (65.30-27.66) with P < 0.001. There was a greater decrease in radicular pain than in LBP following lumbar decompressive only surgery (P = 0.03). Conclusion Patients with symptomatic DLSD and high pre-operative back pain scores without considerable listhesis should anticipate a significant reduction in radicular and back pain intensity, as well as pain-related functional disability, 6 months after non-instrumented lumbar decompressive surgery.

Quality of Life, Disability Level, and Pain Intensity among Patients after Lumbar Disc Surgery: An Observational Three-Month Follow-Up Study. Healthcare (Basel) 2023; 11:3127. [PMID: 38132017 PMCID: PMC10742899 DOI: 10.3390/healthcare11243127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 11/22/2023] [Accepted: 12/02/2023] [Indexed: 12/23/2023] Open
Abstract
The prevalence of intervertebral disc degeneration in the lumbar region resulting in low back pain is high. One of the treatment options is neurosurgery. Previous studies and systematic reviews demonstrate the need to identify factors that affect the health-related quality of life of patients undergoing surgery. This study aimed to analyze the sociodemographic and clinical factors that affect the quality of life of patients undergoing lumbar disc surgery. A group of 128 patients was assessed for eligibility and qualified by radiological examinations for lumbar disc surgery by a neurosurgeon in the outpatient clinic. Finally, 110 patients were studied and evaluated 24 h and 3 months after surgery. Health-related quality of life (36-Item Short Form Survey, SF-36), disability level (Oswestry Disability Index, ODI), and pain intensity (Visual Analogue Scale, VAS) were assessed. The mean pain intensity before surgery was 7.8 ± 2.3 pts and decreased significantly 24 h after surgery, with a mean score of 3.8 ± 2.4 pts (p = 0.0000). After three months, the increase in pain intensity was at 4.8 ± 2.4 pts, but the score was still significantly better than before surgery (p = 0.0024). The mean ODI score before surgery was 29.3 ± 8.4 pts (slight disability), and three months after surgery, there was an insignificant increase to a mean value of 31.5 ± 10.4 pts (p = 0.0834). There was a statistically significant increase in quality-of-life scores at three months after surgery in the following domains: physical functioning (8.7%; p = 0.0176), bodily pain (26.2%; p = 0.0000), vitality (5.8%; p = 0.0132) and mental health (6.2%; p = 0.0163), and a decrease in role limitations due to physical problems (3.8; p = 0.0013) and general health perception (6.7%; p = 0.0112). In conclusion, the surgical procedure plays an important role in improving the quality of life of patients operated on for intervertebral disc degeneration. It was effective in reducing the pain level, especially 24 h after surgery; however, surgery did not affect the disability level.

Abstract
Chronic post-surgical pain is reported by up to 40% of patients after lumbar microdiscectomy for sciatica, a complaint associated with disability and loss of productivity. We conducted a systematic review of observational studies to explore factors associated with persistent leg pain and impairments after microdiscectomy for sciatica. We searched eligible studies in MEDLINE, Embase, and CINAHL that explored, in an adjusted model, predictors of persistent leg pain, physical impairment, or failure to return to work after microdiscectomy for sciatica. When possible, we pooled estimates of association using random-effects models using the Grading of Recommendations Assessment, Development, and Evaluation approach. Moderate-certainty evidence showed that the female sex probably has a small association with persistent post-surgical leg pain (odds ratio (OR) = 1.15, 95% confidence interval (CI) = 0.63 to 2.08; absolute risk increase (ARI) = 1.8%, 95% CI = -4.7% to 11.3%), large association with failure to return to work (OR = 2.79, 95% CI = 1.27 to 6.17; ARI = 10.6%, 95% CI = 1.8% to 25.2%), and older age is probably associated with greater postoperative disability (β = 1.47 points on the 100-point Oswestry Disability Index for every 10-year increase from age (>/=18 years), 95% CI = -4.14 to 7.28). Among factors that were not possible to pool, two factors showed promise for future study, namely, legal representation and preoperative opioid use, which showed large associations with worse outcomes after surgery. The moderate-certainty evidence showed female sex is probably associated with persistent leg pain and failure to return to work and that older age is probably associated with greater post-surgical impairment after a microdiscectomy. Future research should explore the association between legal representation and preoperative opioid use with persistent pain and impairment after microdiscectomy for sciatica.

Abstract
This study aimed to assess the quality of life of 113 Caucasian patients with intervertebral disc (IVD) degeneration of the lumbosacral (L/S) spine who qualified for microdiscectomy during a 12-month period after surgery. Based on magnetic resonance imaging before the surgery, the degree of radiological advancement of the degenerative changes was determined according to the Pfirrmann grading scale from 1 to 5. To assess pain intensity, the Visual Analog Scale (VAS) was used; the Satisfaction with Life Scale (SWLS) was used to evaluate quality of life; and to assess the degree of ability, the Oswestry Low Back Pain Disability Questionnaire (ODI) was employed. The level of pain, assessed using the VAS, significantly changed in the months following the surgery, with the highest values noted before surgery and the lowest a year after. In turn, the results of the SWLS questionnaire revealed a significant increase in satisfaction with life in the subsequent stages of the study. The conducted correlation analysis revealed significant dependencies in terms of quality of life in regard to pain as well as degree of disability. The level of pain and degree of disability were closely related to the degree of radiological advancement of degenerative changes according to the Pfirrmann grading scale.

Poor Muscle Health and Low Preoperative ODI are Independent Predictors for Slower Achievement of MCID After Minimally Invasive Decompression. Spine J 2023:S1529-9430(23)00157-2. [PMID: 37059307 DOI: 10.1016/j.spinee.2023.04.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 02/27/2023] [Accepted: 04/07/2023] [Indexed: 04/16/2023]
Abstract
BACKGROUND CONTEXT Although some previous studies have analyzed predictors of non-improvement, most of these have focused on demographic and clinical variables and have not accounted for radiological predictors. In addition, while several studies have examined the degree of improvement after decompression, there is less data on the rate of improvement. PURPOSE To identify the risk factors and predictors (both radiological and non-radiological) for slower as well as non-achievement of minimal clinically important difference (MCID) after minimally invasive decompression. DESIGN Retrospective cohort PATIENT SAMPLE: Patients who underwent minimally invasive decompression for degenerative lumbar spine conditions and had a minimum of 1-year follow-up were included. Patients with preoperative Oswestry Disability Index (ODI) <20 were excluded. OUTCOME MEASURE MCID achievement in ODI (cut off 12.8). METHODS Patients were stratified into two groups (achieved MCID, did not achieve MCID) at two timepoints (early ≤3 months, late ≥6 months). Non-radiological (age, gender, BMI, comorbidities, anxiety, depression, number of levels operated, preoperative ODI, preoperative back pain) and radiological (MRI - Schizas grading for stenosis, dural sac cross-sectional area, Pfirrmann grading for disc degeneration, psoas cross-sectional area and Goutallier grading, facet cyst/effusion; X-ray - spondylolisthesis, lumbar lordosis, spinopelvic parameters) variables were assessed with comparative analysis to identify risk factors and with multiple regression models to identify predictors for slower achievement of MCID (MCID not achieved by ≤3 months) and non-achievement of MCID (MCID not achieved at ≥6 months). RESULTS 338 patients were included. At ≤3 months, patients who did not achieve MCID had significantly lower preoperative ODI (40.1 vs. 48.1, p<0.001) and worse psoas Goutallier grading (p=0.048). At ≥6 months, patients who did not achieve MCID had significantly lower preoperative ODI (38 vs. 47.5, p<0.001), higher age (68 vs. 63 years, p=0.007), worse average L1-S1 Pfirrmann grading (3.5 vs. 3.2, p=0.035), and higher rate of pre-existing spondylolisthesis at the operated level (p=0.047). When these and other probable risk factors were put into a regression model, low preoperative ODI (p=0.002) and poor Goutallier grading (p=0.042) at the early timepoint and low preoperative ODI (p<0.001) at the late timepoint came out as independent predictors for MCID non-achievement. CONCLUSION After minimally invasive decompression, low preoperative ODI and poor muscle health are risk factors and predictors for slower achievement of MCID. For non-achievement of MCID, low preoperative ODI, higher age, greater disc degeneration, and spondylolisthesis are risk factors and low preoperative ODI is the only independent predictor.

Abstract
BACKGROUND CONTEXT Low back pain with or without radicular leg pain is an extremely common health condition significantly impacting patient's activities and quality of life. When conservative management fails, epidural injections providing only temporary relief, are frequently utilized. Intradiscal oxygen-ozone may offer an alternative to epidural injections and further reduce the need for microdiscectomy. PURPOSE To compare the non-inferiority treatment status and clinical outcomes of intradiscal oxygen-ozone with microdiscectomy in patients with refractory radicular leg pain due to single-level contained lumbar disc herniations. STUDY DESIGN / SETTING Multicenter pilot prospective non-inferiority blocked randomized control trial conducted in three European hospital spine centers. PATIENT SAMPLE Forty-nine patients (mean 40 years of age, 17 females/32 males) with a single-level contained lumbar disc herniation, radicular leg pain for more than six weeks, and resistant to medical management were randomized, 25 to intradiscal oxygen-ozone and 24 to microdiscectomy. 88% (43 of 49) received their assigned treatment and constituted the AS-Treated (AT) population. OUTCOME MEASURES Primary outcome was overall 6-month improvement over baseline in leg pain. Other validated clinical outcomes, including back numerical rating pain scores (NRS), Roland Morris Disability Index (RMDI) and EQ-5D, were collected at baseline, 1 week, 1-, 3-, and 6-months. Procedural technical outcomes were recorded and adverse events were evaluated at all follow-up intervals. METHODS Oxygen-ozone treatment performed as outpatient day surgeries, included a one-time intradiscal injection delivered at a concentration of 35±3 μg/cc of oxygen-ozone by a calibrated delivery system. Discectomies performed as open microdiscectomy inpatient surgeries, were without spinal instrumentation, and not as subtotal microdiscectomies. Primary analyses with a non-inferiority margin of -1.94-point difference in 6-month cumulative weighted mean leg pain NRS scores were conducted using As-Treated (AT) and Intent-to-Treat (ITT) populations. In post hoc analyses, differences between treatment groups in improvement over baseline were compared at each follow-up visit, using baseline leg pain as a covariate. RESULTS In the primary analysis, the overall 6-month difference between treatment groups in leg pain improvement using the AT population was -0.31 (SE, 0.84) points in favor of microdiscectomy and using the ITT population, the difference was 0.32 (SE, 0.88) points in favor of oxygen-ozone. The difference between oxygen-ozone and microdiscectomy did not exceed the non-inferiority 95% confidence lower limit of treatment difference in either the AT (95% lower limit, -1.72) or ITT (95% lower limit, -1.13) populations. Both treatments resulted in rapid and statistically significant improvements over baseline in leg pain, back pain, RMDI, and EQ-5D that persisted in follow-up. Between group differences were not significant for any outcomes. During 6-month follow-up, 71% (17 of 24) of patients receiving oxygen-ozone, avoided microdiscectomy. The mean procedure time for oxygen-ozone was significantly faster than microdiscectomy by 58 minutes (p<.0010) and the mean discharge time from procedure was significantly shorter for the oxygen-ozone procedure (4.3±2.9 hours vs. 44.2±29.9 hours, p<.001). No major adverse events occurred in either treatment group. CONCLUSIONS Intradiscal oxygen-ozone chemonucleolysis for single-level lumbar disc herniations unresponsive to medical management, met the non-inferiority criteria to microdiscectomy on 6-month mean leg pain improvement. Both treatment groups achieved similar rapid significant clinical improvements that persisted and overall, 71% undergoing intradiscal oxygen-ozone were able to avoid surgery.

Abstract
Entrapment neuropathies such as carpal tunnel syndrome, radiculopathies, or radicular pain are the most common peripheral neuropathies and also the most common cause for neuropathic pain. Despite their high prevalence, they often remain challenging to diagnose and manage in a clinical setting. Summarising the evidence from both preclinical and clinical studies, this review provides an update on the aetiology and pathophysiology of entrapment neuropathies. Potenzial mechanisms are put in perspective with clinical findings. The contemporary assessment is discussed and diagnostic pitfalls highlighted. The evidence for the noninvasive and surgical management of common entrapment neuropathies is summarised and future areas of research are identified.

Abstract
STUDY DESIGN Retrospective analysis. OBJECTIVE Lumbar disc herniation is one the most common condition responsible for low back and radicular pain. Although the symptoms are not proportional to the size of disc prolapse but massive disc herniation frequently needs surgical management. According to literature, the incidence of low back pain, recurrent disc herniation and segmental instability are more in discectomy whereas incidence of adjacent segment degeneration (ASD) is more after fusion surgery. There are very few studies that directly compare long-term functional outcome of both these procedures. We compared the functional outcome of both the procedures in this study. METHODS All patients of massive disc prolapse, operated at our center between 2011 to 2017, were contacted. All the patients underwent either discectomy or transforaminal lumbar interbody fusion (TLIF). Functional outcomes of all the patients were collected using visual analogue scale (VAS) (back), VAS (leg), modified Oswestry Disability Index (mODI), Sciatica Bothersomeness Index (SBI), and McNab's criterion. Various complications were also analyzed. RESULTS There were 144 patients in the discectomy group and 123 patients in the TLIF group. Mean duration of follow-up was 55.07 months and 51.86 months, respectively. Both the groups show no significant difference in VAS. Significant difference was seen in mODI and SBI favoring discectomy. McNab's criterion showed excellent result in 80% of patients of discectomy compared with 68% patients of TLIF. Overall complication rate in discectomy group was 11% whereas 13% in TLIF group. CONCLUSION Both show good functional outcome but better in discectomy. Recurrent herniation and instability were noticed more with discectomy and ASD was more common after fusion surgeries. The choice of procedure should be individualized, and it also depends on surgical expertise, but in developing countries where resources are constrained, discectomy should be preferred.

A prognostic model for failure and worsening after lumbar microdiscectomy: a multicenter study from the Norwegian Registry for Spine Surgery. Acta Neurochir (Wien) 2021; 163:2567-2580. [PMID: 34245366 PMCID: PMC8357664 DOI: 10.1007/s00701-021-04859-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Accepted: 04/19/2021] [Indexed: 01/27/2023]
Abstract
OBJECTIVE To develop a prognostic model for failure and worsening 1 year after surgery for lumbar disc herniation. METHODS This multicenter cohort study included 11,081 patients operated with lumbar microdiscectomy, registered at the Norwegian Registry for Spine Surgery. Follow-up was 1 year. Uni- and multivariate logistic regression analyses were used to assess potential prognostic factors for previously defined cut-offs for failure and worsening on the Oswestry Disability Index scores 12 months after surgery. Since the cut-offs for failure and worsening are different for patients with low, moderate, and high baseline ODI scores, the multivariate analyses were run separately for these subgroups. Data were split into a training (70%) and a validation set (30%). The model was developed in the training set and tested in the validation set. A prediction (%) of an outcome was calculated for each patient in a risk matrix. RESULTS The prognostic model produced six risk matrices based on three baseline ODI ranges (low, medium, and high) and two outcomes (failure and worsening), each containing 7 to 11 prognostic factors. Model discrimination and calibration were acceptable. The estimated preoperative probabilities ranged from 3 to 94% for failure and from 1 to 72% for worsening in our validation cohort. CONCLUSION We developed a prognostic model for failure and worsening 12 months after surgery for lumbar disc herniation. The model showed acceptable calibration and discrimination, and could be useful in assisting physicians and patients in clinical decision-making process prior to surgery.

Abstract
Entrapment neuropathies such as carpal tunnel syndrome, radiculopathies, or radicular pain are the most common peripheral neuropathies and also the most common cause for neuropathic pain. Despite their high prevalence, they often remain challenging to diagnose and manage in a clinical setting. Summarising the evidence from both preclinical and clinical studies, this review provides an update on the aetiology and pathophysiology of entrapment neuropathies. Potential mechanisms are put in perspective with clinical findings. The contemporary assessment is discussed and diagnostic pitfalls highlighted. The evidence for the noninvasive and surgical management of common entrapment neuropathies is summarised and future areas of research are identified.

Abstract
Background Previous studies have demonstrated bone-anchored annular closure to significantly reduce reherniation and reoperation rates after lumbar discectomy in patients with large annular defects. It is important to identify the prognostic factors that may be associated with successful treatment. This study aimed to identify predictors of treatment success in patients with lumbar disc herniation treated with limited microdiscectomy supplemented by a bone-anchored annular closure device (ACD). Methods This study was a retrospective analysis of 133 consecutive patients with lumbar disc herniation treated with the ACD. Treatment success was defined as ≥24% improvement in visual analog scale (VAS) for back pain, ≥39% improvement in VAS leg pain, and ≥33% in the Oswestry Disability Index (ODI), with the raw ODI score ≤48. Success was calculated at 3, 6, and 12 months after surgery. Potentially predictive outcomes included patient characteristics, operative data, and imaging outcomes, such as disc, facet, and end plate morphology. Logistic regression was used to determine the significant predictive factors for treatment success. Results After 3, 6, and 12 months, 97 of 131 (74%), 104 of 129 (81%), and 112 of 126 (89%) patients, respectively, achieved the success criteria. At 3 months follow-up, a higher proportion of younger (17-40 years) versus older (41-65 years) patients met the success criteria (P = .025). On the basis of logistic regression, the following factors were significantly associated with treatment success at 1 or more of the follow-up time points: sex (male), lower body mass index, higher baseline pain and ODI scores, lower grade preoperative disc degeneration, and the absence of a postoperative complication. The rates of index-level recurrent herniation and reoperation were 1.5% and 3.0%, respectively. Conclusions This real-world evidence supports a promising benefit-risk profile for augmenting limited microdiscectomy with a bone-anchored ACD and provides some insights into the patient populations that may have a greater chance of realizing significant improvements in pain and function. Level of Evidence 2 (Cohort study).

Abstract
OBJECTIVE Few studies describe long-term functional outcomes of pediatric patients who have undergone lumbar microdiscectomy (LMD) because of the rarity of pediatric disc herniation and the short follow-up periods. The authors analyzed risk factors, clinical presentation, complications, and functional outcomes of a single-institution series of LMD patients over a 19-year period. METHODS A retrospective case series was conducted of pediatric LMD patients at a large pediatric academic hospital from 1998 to 2017. The authors examined premorbid risk factors, clinical presentation, physical examination findings, type and duration of conservative management, indications for surgical intervention, complications, and postoperative outcomes. RESULTS Over the 19-year study period, 199 patients underwent LMD at the authors' institution. The mean age at presentation was 16.0 years (range 12-18 years), and 55.8% were female. Of these patients, 70.9% participated in competitive sports, and among those who did not play sports, 65.0% had a body mass index greater than 25 kg/m2. Prior to surgery, conservative management had failed in 98.0% of the patients. Only 3 patients (1.5%) presented with cauda equina syndrome requiring emergent microdiscectomy. Complications included 4 cases of postoperative CSF leak (2.0%), 1 case of a noted intraoperative CSF leak, and 3 cases of wound infection (1.5%). At the first postoperative follow-up appointment, minimal or no pain was reported by 93.3% of patients. The mean time to return to sports was 9.8 weeks. During a mean follow-up duration of 8.2 years, 72.9% of patients did not present again after routine postoperative appointments. The total risk of reoperation was a rate of 7.5% (3.5% of patients underwent reoperation for the same level; 4.5% underwent adjacent-level decompression, and one patient [0.5%] ultimately underwent a fusion). CONCLUSIONS Microdiscectomy is a safe and effective treatment for long-term relief of pain and return to daily activities among pediatric patients with symptomatic lumbar disc disease in whom conservative management has failed.

Abstract
INTRODUCTION Lumbar discectomy is a widely used surgical procedure internationally with the majority of patients experiencing significant benefit. However, approximately 20% of patients report suboptimal functional recovery and quality of life. The impact and meaning of the surgical experience from the patients' perspective are not fully understood. Furthermore, there is limited evidence guiding postoperative management with significant clinical practice variation and it is unclear if current postoperative support is valued, beneficial or meets patients' needs and expectations. This study aims to address the evidence gap by moving beyond current knowledge to gain insight into the lived experiences relating to patients' lumbar discectomy surgery journey. Results will inform more meaningful and specific care, thus, enhance rehabilitation and outcomes. METHODS AND ANALYSIS A qualitative investigation using interpretative phenomenology analysis (IPA) will provide a flexible inductive research approach. A purposive sample (n=20) of patients undergoing primary discectomy will be recruited from one UK NHS secondary care centre. Semi-structured interviews will be conducted postsurgery discharge. A topic guide, developed from the literature and our previous work with input from two patient co-investigators, will guide interviews with the flexibility to explore interesting or patient-specific points raised. Providing longitudinal data, patients will keep weekly diaries capturing experiences and change over time throughout 12 months following surgery. A second interview will be completed 1 year postsurgery with its topic guide informed by initial findings. This combination of patient interviews and diaries will capture patients' attitudes and beliefs regarding surgery and recovery, facilitators and barriers to progress, experiences regarding return to activities/function and interactions with healthcare professionals. The rich density of data will be thematically analysed in accordance with IPA, supported by NVivo software. ETHICS AND DISSEMINATION Ethical approval has been granted by the London-Bloomsbury Research Ethics Committee (18/LO/0459; IRAS 241345). Conclusions will be disseminated through conferences and peer-reviewed journals.

Abstract
STUDY DESIGN Prospective, observational cohort study. OBJECTIVE Selective nerve root block (SNRB) is an effective, standard interventional procedure for failed medical management in lumbar disc herniation (LDH). However, the factors that would predict successful outcomes in patients undergoing SNRB have not been clearly studied. METHODS Patients with failed conservative treatment for acute LDH, treated with SNRB were periodically followed till 1 year. Patients who failed to have pain relief or had recurrent pain after SNRB, underwent surgery. The pattern of radiculogram during SNRB was classified into 4 types-"arm," "arrow," "linear," and "splash." Various clinical factors, radiological factors, and radiculograms were compared between patients who had consistent pain relief (group A) and those patients who did not (group B). RESULTS A total of 91 patients underwent SNRB. Sixty-nine had good pain relief maintained till 1 year (75.8% success). Twenty-two patients underwent surgery after failed NRB at a mean of 6.3 weeks. Patients with sensory symptoms (P = .01), higher mean preinjection Oswestry Disability Index (ODI) score (P = .02), higher mean postinjection ODI score at 3 weeks (P = .004), nonmanual job (P = .01), lumbosacral transitional segment (P = .00 005), and splash pattern of radiculogram (P = .005) were predictive of failed NRB. Logistic regression analysis showed that lumbosacral transitional segment at the level of LDH is the most significant factor predicting poor outcome. CONCLUSIONS SNRB is an effective technique to provide consistent symptom relief at least till 1 year in patients with acute LDH. The study identified several factors that predicted poor outcomes of SNRB and such patients can be forewarned about need for later surgery.

Abstract
BACKGROUND Success rates for lumbar discectomy are estimated as 78-95% patients at 1-2 years post-surgery, supporting its effectiveness. However, ongoing pain and disability is an issue for some patients, and recurrence contributing to reoperation is reported. It is important to identify prognostic factors predicting outcome to inform decision-making for surgery and rehabilitation following surgery. The objective was to determine whether pre-operative physical factors are associated with post-operative outcomes in adult patients [≥16 years old] undergoing lumbar discectomy or microdiscectomy. METHODS A systematic review was conducted according to a registered protocol [PROSPERO CRD42015024168]. Key electronic databases were searched [PubMed, CINAHL, EMBASE, MEDLINE, PEDro and ZETOC] using pre-defined terms [e.g. radicular pain] to 31/3/2017; with additional searching of journals, reference lists and unpublished literature. Prospective cohort studies with ≥1-year follow-up, evaluating candidate physical prognostic factors [e.g. leg pain intensity and straight leg raise test], in adult patients undergoing lumbar discectomy/microdiscectomy were included. Two reviewers independently searched information sources, evaluated studies for inclusion, extracted data, and assessed risk of bias [QUIPS]. GRADE determined the overall quality of evidence. RESULTS 1189 title and abstracts and 45 full texts were assessed, to include 6 studies; 1 low and 5 high risk of bias. Meta-analysis was not possible [risk of bias, clinical heterogeneity]. A narrative synthesis was performed. There is low level evidence that higher severity of pre-operative leg pain predicts better Core Outcome Measures Index at 12 months and better post-operative leg pain at 2 and 7 years. There is very low level evidence that a lower pre-operative EQ-5D predicts better EQ-5D at 2 years. Low level evidence supports duration of leg pain pre-operatively not being associated with outcome, and very low-quality evidence supports other factors [pre-operative ODI, duration back pain, severity back pain, ipsilateral SLR and forward bend] not being associated with outcome [range of outcome measures used]. CONCLUSION An adequately powered low risk of bias prospective observational study is required to further investigate candidate physical prognostic factors owing to existing low/very-low level of evidence.

Abstract
PURPOSE The purpose of the study was to investigate the trajectory and determinants of changes in health-related quality of life (HRQoL) in the first year after lumbar spine surgery. METHODS A total of 154 consecutive patients who underwent lumbar spine surgery were included in this prospective longitudinal observational study. All participants were asked to complete a battery of questionnaires (Taiwanese version of World Health Organization Quality of Life-BREF, Numerical Rating Scale for leg and back pain, Mandarin Chinese version of the Clinically Useful Depression Outcome Scale, and Chinese version of the Pittsburgh Sleep Quality Index). The Japanese Orthopedic Association score was evaluated by neurosurgeons. The measurement time points were 1 week before and on the first, sixth, and twelfth month after lumbar spinal surgery. A linear mix model was used for data analyses. RESULTS The analyses revealed significant upward trends in HRQoL, particularly in physical health and social relationships during the study period. Patients who aged < 65 years and reported a higher level of functional status experienced a more favorable HRQoL in physical health over time (p = .002 and .02, respectively). Participants who complained of poor sleep quality yielded poorer HRQoL in physical health over time (p = .03). More severe depressive symptom was associated with the poorer HRQoL in social relationships over time (p < .001). CONCLUSIONS To improve the HRQoL, healthcare providers need to pay attention to changes in sleep quality, neurological functions, and depressive symptoms in people receiving lumbar surgery, particularly individuals with increasing age. Concrete interventions and strategies aimed to enhancing HRQoL in these patients are essential.

Abstract
INTRODUCTION Epidural steroid is an important modality in the conservative management of prolapsed lumbar disc and is being used for over 50 years. However, controversy still persists regarding their effectiveness in reducing the pain and improving the function with literature both supporting and opposing them are available. AIM To study the efficacy of epidural steroid injection in the management of pain due to prolapsed lumbar intervertebral disc and to compare the effectiveness between caudal, transforaminal and interlaminar routes of injection. MATERIALS AND METHODS A total of 152 patients with back pain with or without radiculopathy with a lumbar disc prolapse confirmed on MRI, were included in the study and their pre injection Japanese Orthopaedic Association (JOA) Score was calculated. By simple randomization method (picking a card), patients were enrolled into one of the three groups and then injected methyl prednisone in the epidural space by one of the techniques of injection i.e. caudal, transforaminal and interlaminar. Twelve patients didn't turn up for the treatment and hence were excluded from the study. Remaining 140 patients were treated and were included for the analysis of the results. Eighty two patients received injection by caudal route, 40 by transforaminal route and 18 by interlaminar route. Post injection JOA Score was calculated at six month and one year and effectiveness of the medication was calculated for each route. The data was compared by LSD and ANOVA method to prove the significance. Average follow-up was one year. RESULTS At one year after injecting the steroid, all three routes were found to be effective in improving the JOA Score (Caudal route in 74.3%, transforaminal in 90% and interlaminar in 77.7%). Transforaminal route was significantly more effective than caudal (p=0.00) and interlaminar route (p=0.03) at both 6 months and one year after injection. No significant difference was seen between the caudal and interlaminar route (p=0.36). CONCLUSION The management of low back pain and radicular pain due to a prolapsed lumbar intervertebral disc by injecting methyl prednisone in epidural space is satisfactory in the current study. All three injection techniques are effective with the best result obtained by transforaminal route.

Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVE To describe the naturally occurring magnetic resonance imaging (MRI) findings after successful microsurgical removal of lumbar disc herniation with repeated MRI examinations. SUMMARY OF BACKGROUND DATA The interpretation of MRI after spinal surgery may be particularly challenging and image findings do not always correlate to clinical findings. Early postoperative MRI has limited value in the evaluation of patients after surgery for lumbar disc herniation. METHODS Prospective study of 30 successfully operated patients, which underwent 3.0 T MRI within 24 h after surgery for lumbar disc herniation and repeated at 6 weeks and 3 months postoperatively. Postoperative image findings (nerve root enhancement, nerve root thickening, displacement or compression of the nerve root, and residual mass size and signal) were assessed quantitatively. Inter-rater reliability was tested. RESULTS Inter-rater reliability between neuroradiologists was moderate for assessed MRI variables. In the immediate postoperative phase, compression or dislocation of the nerve root at the operated level was common. A residual mass at the operated level was seen in 80%, 47%, and 33% after 24 h, 6 weeks, and 3 months, respectively. Postoperative dislocation or compression of the nerve root from residual masses was seen in 67%, 24%, and 14% after 24 h, 6 weeks, and 3 months, respectively. A residual mass with a higher signal than muscle on T2-weighted images was seen in 80%, 30%, and 17% after 24 h, 6 weeks, and 3 months, respectively. CONCLUSION A residual mass with compression or dislocation of the nerve root at the operated level, that disappears over 3 months, is a common MRI finding in patients successfully operated for symptomatic lumbar disc herniation. An expectant approach instead of early reoperations may perhaps be preferred in patients with residual pain and root compression due to residual masses with high T2-signal since these often seem to resolve spontaneously.

Abstract
Purpose Disease-specific measures of the impact of sacroiliac (SI) joint pain on back/pelvis function are not available. The Oswestry Disability Index (ODI) is a validated functional measure for lower back pain, but its responsiveness to SI joint treatment has yet to be established. We sought to assess the validity of ODI to capture disability caused by SI joint pain and the minimum clinically important difference (MCID) after SI joint treatment. Methods Patients (n = 155) participating in a prospective clinical trial of minimally invasive SI joint fusion underwent baseline and follow-up assessments using ODI, visual analog scale (VAS) pain assessment, Short Form 36 (SF-36), EuroQoL-5D, and questions (at follow-up only) regarding satisfaction with the SI joint fusion and whether the patient would have the fusion surgery again. All outcomes were compared from baseline to 12 months postsurgery. The health transition item of the SF-36 and the satisfaction scale were used as external anchors to calculate MCID. MCID was estimated for ODI using four calculation methods: (1) minimum detectable change, (2) average ODI change of patients’ subsets, (3) change difference between patients’ subsets, and (4) receiver operating characteristic (ROC) curve. Results After SI fusion, patients improved significantly (p < .0001) on all measures: SI joint pain (48.8 points), ODI (23.8 points), EQ-5D (0.29 points), EQ-5D VAS (11.7 points), PCS (8.9 points), and MCS (9.2 points). The improvement in ODI was significantly correlated (p < .0001) with SI joint pain improvement (r = .48) and with the two external anchors: SF-36 health transition item (r = .49) and satisfaction level (r = .34). The MCID values calculated for ODI using the various methods ranged from 3.5 to 19.5 points. The ODI minimum detectable change was 15.5 with the health transition item as the anchor and 13.5 with the satisfaction scale as the anchor. Conclusions ODI is a valid measure of change in SI joint health. Hence, researchers and clinicians may rely on ODI scores to measure disability caused by SI pain. We estimated the MCID for ODI to be 13–15 points, which falls within the range of that previously reported for lumbar back pain and indicates that an improvement in disability should be at least 15 % to be beyond random variation.

Nerland US, Jakola AS, Giannadakis C, Solheim O, Weber C, Nygaard ØP, Solberg TK, Gulati S. The Risk of Getting Worse: Predictors of Deterioration After Decompressive Surgery for Lumbar Spinal Stenosis: A Multicenter Observational Study. World Neurosurg 2015; 84:1095-102. [PMID: 26049114 DOI: 10.1016/j.wneu.2015.05.055] [Citation(s) in RCA: 53] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Revised: 05/25/2015] [Accepted: 05/28/2015] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To investigate the frequency and predictors of deterioration after decompressive surgery for single and 2-level lumbar spinal stenosis. METHODS Prospectively collected data were retrieved from the Norwegian Registry for Spine Surgery. Clinically significant deterioration was defined as an 8-point increase in Oswestry disability index (ODI) between baseline and 12 months' follow-up. RESULTS There were 2181 patients enrolled in the study. Of 1735 patients with complete 12 months follow-up, 151 (8.7%) patients reported deterioration. The following variables were significantly associated with deterioration at 12 months' follow-up; decreasing age (odds ratio [OR] 1.02, 95% confidence interval [95% CI] 1.00-1.04, P = 0.046), tobacco smoking (OR 2.10, 95% CI 1.42-3.22, P = 0.000), American Society of Anesthesiologists grade ≥3 (OR 1.80, 95% CI 1.07-2.94, P = 0.025), decreasing preoperative ODI (OR 1.05, 95% CI 1.02-1.07, P = 0.000), previous surgery at the same level (OR 2.00, 95% CI 1.18-3.27, P = 0.009), and previous surgery at other lumbar levels (OR 2.10, 95% CI 1.19-3.53, P = 0.009). CONCLUSIONS Overall risk of clinically significant deterioration in patient-reported pain and disability after decompressive surgery for lumbar spinal stenosis is approximately 9%. Predictors for deterioration are decreasing age, current tobacco smoking, American Society of Anesthesiologists grade ≥3, decreasing preoperative ODI, and previous surgery at same or different lumbar level. We suggest that these predictors should be emphasized and discussed with the patients before surgery.

Abstract
Objective: The purpose of the study was to examine changes in quality of life measures in patients who have undergone an intensive exercise program following a single level microdiskectomy. Design: Randomized controlled trial with blinded examiners. Setting: The study was conducted in outpatient physical therapy clinics. Subjects: Ninety-eight participants (53 male, 45 female) who had undergone a single-level lumbar microdiskectomy allocated to receive exercise and education or education only. Interventions: A 12-week periodized exercise program of lumbar extensor strength and endurance training, and mat and upright therapeutic exercises was administered. Outcome measures: Quality of life was tested with the Short Form 36 (SF-36). Measurements were taken 4–6 weeks postsurgery and following completion of the 12-week intervention program. Since some participants selected physical therapy apart from the study, analyses were performed for both an as-randomized (two-group) design and an as-treated (three-group) design. Results: In the two-group analyses, exercise and education resulted in a greater increase in SF-36 scales, role physical (17.8 vs. 12.1) and bodily pain (13.4 vs. 8.4), and the physical component summary (13.2 vs. 8.9). In the three-group analyses, post-hoc comparisons showed exercise and education resulted in a greater increase in the SF-36 scales, physical function (10.4 vs. 5.6) and bodily pain (13.7 vs. 8.2), and the physical component summary (13.7 vs. 8.9) when compared with usual physical therapy. Conclusions: An intensive, progressive exercise program combined with education increases quality of life in patients who have recently undergone lumbar microdiskectomy.

Abstract
PURPOSE This study evaluated an evidence-based education booklet developed for patients undergoing spinal surgery which was used as a treatment intervention in a multi-centre, factorial, randomised controlled trial (FASTER: Function after spinal treatment, exercise and rehabilitation) investigating the post-operative management of spinal surgery patients. This study sought to determine the acceptability and content of the booklet to patients. METHODS Patients receiving the educational booklet before discharge from hospital as part of the FASTER study were asked to complete an evaluation, which rated the booklet "Your Back Operation" with regard to content, information, usability, etc. using forced and open questions. This assessment was conducted at the same time as the initial 6-week post-operative review performed as part of the larger study. RESULTS Therefore, 97% of the 117 trial participants who returned their 6-week evaluation and randomised to receive a booklet returned their questionnaire. The booklet was highly rated receiving an overall rating of 7 or more out of 10 from 101/111 (91%), and high ratings for content, readability and information. The booklet's key messages were clear to the majority of patients; however, many patients highlighted deficiencies with respect to content particularly in relation to wound care and exercise. CONCLUSIONS Patients valued the booklet and rated its content highly. Many suggested that the booklet be developed further and there was a clear desire for specific exercises to be included even though there is no evidence to support specific exercise prescription.

Abstract
STUDY DESIGN This was a multicenter, factorial, randomized, controlled trial on the postoperative management of spinal surgery patients, with randomization stratified by surgeon and operative procedure. OBJECTIVE This study sought to determine whether the functional outcome of two common spinal operations could be improved by a program of postoperative rehabilitation that combines professional support and advice with graded active exercise commencing 6 weeks after surgery and/or an educational booklet based on evidence-based messages and advice received at discharge from hospital, each compared with usual care. SUMMARY OF BACKGROUND DATA Surgical interventions on the spine are increasing, and while surgery for spinal stenosis and disc prolapse have been shown to be superior to conservative management, functional outcome, and patient satisfaction are not optimal. METHODS The study compared the effectiveness of a rehabilitation program and an education booklet for the postoperative management of patients undergoing discectomy or lateral nerve root decompression surgery, each compared with "usual care" using a 2 × 2 factorial design, randomizing patient to four groups; rehabilitation-only, booklet-only, rehabilitation-plus-booklet, and usual care only. The primary outcome measure was the Oswestry Disability Index (ODI) at 12 months, with secondary outcomes including visual analog scale measures of back and leg pain. RESULTS Three hundred thirty-eight patients were recruited into the study and measurements were obtained preoperatively and then repeated at 6 weeks, 3, 6, 9 and 12 months postoperatively. Twelve months postoperatively the observed effect of rehabilitation on ODI was -2.7 (95% CI: -6.8 to 1.5) and the effect of booklet was 2.7 (95% CI: -1.5 to 6.9). CONCLUSION This study found that neither intervention had a significant impact on long-term outcome.

Abstract
BACKGROUND AND PURPOSE Loss to follow-up may bias the outcome assessments of clinical registries. In this study, we wanted to determine whether outcomes were different in responding and non-responding patients who were included in a clinical spine surgery registry, at two years of follow-up. In addition, we wanted to identify risk factors for failure to respond. METHODS 633 patients who were operated for degenerative disorders of the lumbar spine were followed for 2 years using a local clinical spine registry. Those who did not attend the clinic and those who did not answer a postal questionnaire-for whom 2 years of outcome data were missing-and who would be lost to follow-up according to the standard procedures of the registry protocols, were defined as non-respondents. They were traced and interviewed by telephone. Outcome measures were: improvement in health-related quality of life (EQ-5D), leg pain, and back pain; and also general state of health, employment status, and perceived benefits of the operation. RESULTS We found no statistically significant differences in outcome between respondents (78% of the patients) and non-respondents (22%). Receipt of postal questionnaires (not being summoned for a follow-up visit) was the strongest risk factor for failure to respond. Forgetfulness appeared to be an important cause. Older patients and those who had complications were more likely to respond. INTERPRETATION A loss to follow-up of 22% would not bias conclusions about overall treatment effects and, importantly, there were no indications of worse outcomes in non-respondents.

Abstract
Background The life-time incidence of low back pain is high and diagnoses of spinal stenosis and disc prolapse are increasing. Consequently, there is a steady rise in surgical interventions for these conditions. Current evidence suggests that while the success of surgery is incomplete, it is superior to conservative interventions. A recent survey indicates that there are large differences in the type and intensity of rehabilitation, if any, provided after spinal surgery as well as in the restrictions and advice given to patients in the post-operative period. This trial will test the hypothesis that functional outcome following two common spinal operations can be improved by a programme of post-operative rehabilitation that combines professional support and advice with graded active exercise and/or an educational booklet based on evidence-based messages and advice. Methods/Design The study design is a multi-centre, factorial, randomised controlled trial with patients stratified by surgeon and operative procedure. The trial will compare the effectiveness and cost-effectiveness of a rehabilitation programme and an education booklet for the postoperative management of patients undergoing discectomy or lateral nerve root decompression, each compared with "usual care"using a 2 × 2 factorial design. The trial will create 4 sub-groups; rehabilitation-only, booklet-only, rehabilitation-plus-booklet, and usual care only. The trial aims to recruit 344 patients, which equates to 86 patients in each of the four sub-groups. All patients will be assessed for functional ability (through the Oswestry Disability Index - a disease specific functional questionnaire), pain (using visual analogue scales), and satisfaction pre-operatively and then at 6 weeks, 3, 6 and 9 months and 1 year post-operatively. This will be complemented by a formal analysis of cost-effectiveness. Discussion This trial will determine whether the outcome of spinal surgery can be enhanced by either a post-operative rehabilitation programme or an evidence-based advice booklet or a combination of the two and as such will contribute to our knowledge on how to manage spinal surgery patients in the post-operative period.

Abstract
OBJECTIVES Objectives of this study are (1) to compare health-related quality of life (HRQOL) of patients after lumbar disc surgery with reference data from the German general population; (2) to examine whether changes in HRQOL occur over time; (3) to investigate associations between HRQOL and socio-demographic and health-related factors. METHODS The study sample consisted at baseline of 189 patients who underwent lumbar disc surgery. Baseline assessment was carried out 1-4 days after surgery, the first follow-up 2 months, the second follow-up 6 months after surgery. HRQOL was assessed by means of the WHOQOL-BREF. RESULTS During follow-up, patients showed significant improvement in "physical well being" and "overall quality of life." However, it did not reach the level of the general population at any assessment point. There was also a slight improvement of "psychological well being." The domains "social relationships" and "environment" remained unchanged and showed persistently higher scores than the general population. Cohabitating was positively associated with QoL. Negatively associated were unemployment, part-time employment, desire for early retirement, higher intensity of pain and depression. CONCLUSION Supplementing physical rehabilitation by psychosocial interventions may help improve patients' HRQOL.

Abstract
STUDY DESIGN An in vitro biomechanical study using aged human and adolescent porcine discs. OBJECTIVES To find the leakage pathway and effect of needle gauge on the degree of disc injury post anular puncture. SUMMARY OF BACKGROUND DATA Spinal needles are widely used for minimal invasive disc surgeries and disc degeneration/regeneration research. Applications of anular puncture require different diameters of spinal needles. However, the effect of needle diameters on the disc injury has not been systematically studied yet. METHODS Four groups of experiments were conducted: 1) porcine thoracic disc, 2) human thoracic disc, 3) porcine thoracic disc with 200 N external loading, and 4) porcine lumbar discs. The disc was punctured consecutively with needles from smaller diameter to larger diameter. After each anular puncture, the quantitative discomanometry technique was conducted to quantify the disc rupture pressure and volume. The association between needle gauge and rupture pressure and volume was analyzed. RESULTS The degree of disc injury increased with the diameter of needle. For an aged human thoracic disc, the anulus fibrosus cannot hold pressure more than 2 MPa after a 21-gauge-needle-anular-puncture. The leakage pathway of injected saline was through the anular fissure but was through the endplate when the disc was next to an osteoporotic vertebrae. The pressure holding power of porcine disc is stronger than of human disc. The rupture pressure of porcine lumbar disc is higher than of porcine thoracic disc. The axial compressive external loading increased the disc rupture pressure. The rupture volumes were not affected by the dimension of injury fissure. The rupture volume was at level of 0.3 mL without external loading and at 0.2 mL with external loading. CONCLUSION A spinal needle of < or = 22 gauge and injection volume of < or = 0.2 mL are recommended to prevent postsurgery leakage.

Abstract
Recurrent disc herniation is frequently observed due to leakage of nucleus pulposus through injured anulus fibrosus. There is no effective treatment to prevent recurrent disc herniation yet. In this study, we proposed to implant non-cell-based materials into the porcine disc to stimulate the growth of fibrous tissue and thereby increase the disc functional integrity. The disc herniation was simulated by anular punctures using the spinal needles. Four clinically used implantation materials, i.e., gelfoam, platinum coil, bone cement and tissue glue, were delivered into the discs via percutaneous spinal needles. Two months after the surgery, the swine were killed. The degree of disc integrity of intact, naturally healed and implanted discs, was examined by quantitative discomanometry apparatus. We found the disc injury could not recover after 2 months of healing, and the disc implantation affected the degree of disc integrity. The disc integrity of gelfoam-implanted discs was better than that of coil-, bone cement-, and glue-implanted discs. The implantation of non-cell-based material was proved to be a potentially clinically applicable method to recover the integrity of injured discs and to prevent recurrent disc herniation.

Abstract
BACKGROUND Microsurgical discectomies are an established procedure in spinal surgery. This operating technique was first used in the Department of Neurosurgery in Iceland in 1981 and has become standard operative treatment for herniated lumbar discs. There is a great variability in outcome reports regarding recurrence rate and re-operation rate. Few articles are based on follow-up of more than 10 years. This article presents the results of a 20 years follow-up study. METHODS A retrospective study of all patients undergoing microsurgical discectomy for herniated lumbar disc, from June 1, 1981 to December 31, 1984. Outcome, based on recurrence rate, return to work and patient satisfaction was determined by a self-evaluation questionnaire, phone interviews and patient medical records. FINDINGS Of the 170 patients, 134 (78.8%) were included in the study (M:F, 58:42%). Preoperative symptoms: back pain with sciatica 108 (80.6%), sciatica 20 (14.9%), back pain 2 (1.5%). Mean follow-up time was 20.7 years (19.5-22.8). Recurrence rate was 12.7%. 19 patients (14.2%) underwent a subsequent lumbar operation at a different level or side. A majority of patients 108 (80.6%) returned to previous level of work, 26 (19.4%) lost some or all working capabilities. Patient satisfaction was high, 91.1% reporting excellent (68.7%) or good (22.4%) results. 5.2% of patients rated the outcome fair and 3.7% poor. Women reported worse outcome than men, excellent M:F 74.7:60.7%, and poor 7.1:1.3%. There was no significant difference in patient satisfaction in patients undergoing additional operations or those with recurrence of the herniated disc. CONCLUSIONS Outcome was very good with 92.0% return to work and 91.1% patient satisfaction. The recurrence rate was 12.7% with a substantial number of cases occurring 10-20 years after operation. To conclude, microsurgical discectomies maintain a high success rate in the long-term.

Abstract
UNLABELLED Lumbar disc herniation is among the most common causes of lower-back pain and sciatica. The cause(s) of lumbar disc herniation and the relation of lumbar disc herniation to back pain and sciatica have not been fully elucidated, but most likely comprise a complex combination of mechanical and biologic processes. Furthermore, the natural history of lumbar disc herniation seems generally to be favorable, leaving the optimum treatment for lumbar disc herniation a debate in the literature. Various nonoperative and operative treatment strategies have been tried with varying degrees of success. Treatment often involves patient education, physical therapy, alternative medicine options, and pharmaco-therapy. If these fail, surgical intervention is usually recommended. A literature search was conducted to evaluate the currently known effectiveness of traditional and novel non-operative and surgical techniques for the treatment lumbar disc herniation and to determine if there are substantive new advantages in these newer contemporary treatments or combinations thereof. A structured approach to treatment of a patient who may have a symptomatic lumbar disc herniation is presented, based on analysis of the current literature. No one method of nonoperative or operative treatment would seem definitively to be superior to another. Appropriate multidisciplinary treatment including behavioral analysis and support may offer the hope of improved outcomes for patients with lumbar disc herniation. LEVEL OF EVIDENCE Level V (expert opinion). See the Guidelines for Authors for a complete description of the levels of evidence.

Abstract
Prevention of work disability is a primary goal within treatment of spinal disorders. Work-related outcome measures therefore are essential indices within evidence-based medicine. So far many measures suffer, however, from standardized measurement, standardized terminology, and a lack of theoretical background. This review addresses traditional indicators like work status and sickness absence, and discusses more theory-bound concepts, i.e. work ability, occupational risk factors for recurrence of symptoms and re-injury, work-related attitudes that may become obstacles to recovery, and individual reactions to occupational stressors that increase the risk of maintenance and recurrence of symptoms. The review includes methodological and theoretical considerations and recommendations for the use of work-related outcome measures in future outcome research.

Abstract
The relatively high rate of failed back surgery has prompted the search for "risk factors" to predict the result of spinal surgery in a given individual. However, the literature reveals few unequivocal predictors and they often explain a relatively low proportion of variance in outcome. This suggests that we have a long way to go before being able to rest easily, having refused someone surgery on the basis of unfavourable baseline characteristics. The best recommendation is to ensure, firstly, that the indication for surgery is absolutely clear-cut (i.e. that surgically remediable pathology exists) and then to consider the various factors that may influence the "typical" outcome. Consistent risk factors for a poor outcome regarding return-to-work include long-term sick leave/receipt of disability benefit. Hence, every effort should be made to keep the individual in the workforce, despite the ongoing symptoms and plans for surgery. In patients with a particularly heavy job, consultation with occupational physicians might later ease the patient's way back into the workplace. Patients with degenerative disorders and/or comorbidity should be counselled that few of them will have complete/lasting pain relief or a complete return to pre-morbid function. Patients with a high level of distress may benefit from psychological treatment, before and/or accompanying the surgical treatment. The opportunity (time), encouragement (education and positive messages), and resources (referral to appropriate support services) to modify risk factors that are indeed modifiable should be offered, and realistic expectations should be discussed with the patient before the decision to operate is made.
