[PMID: 38835174 DOI: 10.3238/arztebl.m2024.0074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 04/10/2024] [Accepted: 04/10/2024] [Indexed: 06/06/2024]
Abstract
BACKGROUND Lumbar disc surgery is among the more common spinal procedures. In this paper, we report the current treatment recommendations for patients with symptomatic disc herniation. METHODS This review is based on pertinent publications retrieved by a selective literature search in PubMed using the terms [timing] AND [lumbar disc herniation], supplemented by other relevant articles and guidelines. RESULTS Symptoms resolve in 60% to 80% of patients with herniated discs in 6-12 weeks, and in 80% to 90% over the long term (≥ 1 year). According to the guidelines, 6-12 weeks of conservative treatment are recommended in the absence of significant neu - rologic deficits. Early surgery is indicated in case of worsening pain or new onset of neurologic deficits. Lumbar disc herniation associated bladder or bowel dysfunction (cauda equina syndrome) is considered an absolute surgical emergency that requires immediate decompression (within 24 to 48 hours). Patients with severe motor deficits (MRC ≤ 3/5) benefit from early intervention and should be offered surgery within three days, if possible, for the best chance of recovery. The degree of weakness and the duration of symptoms have been identified as risk factors for incomplete recovery. Early surgery can be considered in patients with mild paresis (MRC 4/5) in case of functional impairment (e.g., quadriceps paresis). CONCLUSION Longer symptom duration and lower motor scores are associated with worse outcome and a lower chance of neurologic recovery. The recovery rate for motor deficits ranges from 33% to 75%, depending on the timing and modality of treatment as well as the motor score.

Abstract
STUDY DESIGN Prospective study. PURPOSE To propose a scoring system for predicting the need for surgery in patients with lumbar disc herniation (LDH). OVERVIEW OF LITERATURE The indications for surgery in patients with LDH are well established. However, the exact timing of surgery is not. According to surgeons, patients with failed conservative treatment who underwent delayed surgery, often after 6 months postsymptom initiation, have poor functional recovery and outcome. METHODS The current study included patients with symptomatic LDH. Patients with an indication for emergent surgery such as profound or progressive motor deficit, cauda equina syndrome, and diagnoses other than single-level LDH were excluded from the analysis. All patients followed a conservative treatment regimen (a combination of physical therapy, pain medications, and/or spinal epidural steroid injections). Surgery was indicated for patients who continuously experienced pain despite maximal conservative therapy. RESULTS In total, 134 patients met the inclusion and exclusion criteria. Among them, 108 (80.6%) responded to conservative management, and 26 (19.4%) underwent unilateral laminotomy and microdiscectomy. The symptom duration, disc degeneration grade on magnetic resonance imaging (Pfirrmann disc grade), herniated disc location and type, fragment size, and thecal sac diameter significantly differed between patients who responded to conservative treatment and those requiring surgery. The area under the receiver operating characteristic curve of the scoring system based on the anteroposterior size of the herniated disc fragment and herniated disc location and type was 0.81. CONCLUSIONS A scoring system based on herniated disc/fragment size, location, and type can be applied to predict the need for surgery in patients with LDH. In the future, this tool can be used to prevent unnecessarily prolonged conservative management (>4-8 weeks).

Abstract
STUDY DESIGN A retrospective cohort study. OBJECTIVE The aim of the study was to assess the impact of time to surgery in patients with motor deficits (MDs) on their functional outcome. The current single-center study presents results of emergency surgery for LDH in a group of patients with acute paresis in a "real-world" setting. SUMMARY OF BACKGROUND DATA MDs are a frequent symptom of lumbar disc herniation (LDH). Although surgery within 48 hours has been recommended for cauda-equina syndrome, the best timing of surgery for acute MDs continues to be debated. The effect of early surgery has been proposed but remains to be unproven. METHODS A total of 330 patients with acute paresis caused by LDH acutely referred to our department and surgically treated using microsurgical discectomy from January 2013 to December 2015 were included. Based on the duration of MD and surgical timing, all patients were classified into two categories: Group I included all patients with paresis <48 hours and Group II included all patients with paresis >48 hours. Patient demographics, LDH/clinical/treatment characteristics, and outcomes were collected prospectively.Severity of paresis [Medical Research Council (MRC) Grade 0-4], surgery-related complications, functional recovery of motor/sensory deficits, sciatica, retreatment/recurrence rates, and overall neurological outcome were analyzed. RESULTS Group I showed significantly faster recovery of moderate/severe paresis (MRC 0-3) at discharge, and 6-weeks/3-months follow up (P ≤ 0.001), whereas there were no significant differences in recovery for mild paresis (MRC 4). Sensory deficits also recovered substantially faster in Group I at 6-weeks (P = 0.003) and 3-months follow up (P = 0.045). Body mass index, preoperative MRC-grade, and duration of MDs were identified as significant predictors for recovery of paresis at all follow ups with substantial impact on patient reported outcomes including sciatica and/or dermatomal sensory deficits. CONCLUSION Given the superior rates of neurological recovery of acute moderate/severe MDs, immediate surgery should be the primary option. However, a prospective randomized clinical trial is needed to confirm the superiority of emergency surgery. LEVEL OF EVIDENCE 3.

Abstract
Background Percutaneous laser disc decompression is a minimally invasive treatment, for lumbar disc herniation and might serve as an alternative to surgical management of sciatica. In a randomised trial with two-year follow-up we assessed the clinical effectiveness of percutaneous laser disc decompression compared to conventional surgery. Materials and methods This multicentre randomised prospective trial with a non-inferiority design, was carried out according to an intent-to-treat protocol with full institutional review board approval. One hundred and fifteen eligible surgical candidates, with sciatica from a disc herniation smaller than one-third of the spinal canal, were randomly allocated to percutaneous laser disc decompression ( n = 55) or conventional surgery ( n = 57). The main outcome measures for this trial were the Roland-Morris Disability Questionnaire for sciatica, visual analogue scores for back and leg pain and the patient's report of perceived recovery. Results The primary outcome measures showed no significant difference or clinically relevant difference between the two groups at two-year follow-up. The re-operation rate was 21% in the surgery group, which is relatively high, and with an even higher 52% in the percutaneous laser disc decompression group. Conclusion At two-year follow-up, a strategy of percutaneous laser disc decompression, followed by surgery if needed, resulted in non-inferior outcomes compared to a strategy of microdiscectomy. Although the rate of reoperation in the percutaneous laser disc decompression group was higher than expected, surgery could be avoided in 48% of those patients that were originally candidates for surgery. Percutaneous laser disc decompression, as a non-surgical method, could have a place in the treatment arsenal of sciatica caused by contained herniated discs.

Abstract
OBJECTIVES Pain relief has been shown to be the most frequently reported goal by patients undergoing lumbar disc surgery. There is a lack of systematic research investigating the course of postsurgical pain intensity and factors associated with postsurgical pain. This systematic review focuses on pain, the most prevalent symptom of a herniated disc as the primary outcome parameter. The aims of this review were (1) to examine how pain intensity changes over time in patients undergoing surgery for a lumbar herniated disc and (2) to identify socio-demographic, medical, occupational and psychological factors associated with pain intensity. METHODS Selection criteria were developed and search terms defined. The initial literature search was conducted in April 2015 and involved the following databases: Web of Science, Pubmed, PsycInfo and Pubpsych. The course of pain intensity and associated factors were analysed over the short-term (≤ 3 months after surgery), medium-term (> 3 months and < 12 months after surgery) and long-term (≥ 12 months after surgery). RESULTS From 371 abstracts, 85 full-text articles were reviewed, of which 21 studies were included. Visual analogue scales indicated that surgery helped the majority of patients experience significantly less pain. Recovery from disc surgery mainly occurred within the short-term period and later changes of pain intensity were minor. Postsurgical back and leg pain was predominantly associated with depression and disability. Preliminary positive evidence was found for somatization and mental well-being. CONCLUSIONS Patients scheduled for lumbar disc surgery should be selected carefully and need to be treated in a multimodal setting including psychological support.

Abstract
Objectives The aims of this study are to answer the following questions (1) How does the pain intensity of lumbar and cervical disc surgery patients change within a postoperative time frame of 5 years? (2) Which sociodemographic, medical, work-related, and psychological factors are associated with postoperative pain in lumbar and cervical disc surgery patients? Methods The baseline survey (T0; n = 534) was conducted 3.6 days (SD 2.48) post-surgery in the form of face-to-face interviews. The follow-up interviews were conducted 3 months (T1; n = 486 patients), 9 months (T2; n = 457), 15 months (T3; n = 438), and 5 years (T4; n = 404) post-surgery. Pain intensity was measured on a numeric rating-scale (NRS 0–100). Estimated changes to and influences on postoperative pain by random effects were accounted by regression models. Results Average pain decreased continuously over time in patients with lumbar herniated disc (Wald Chi² = 25.97, p<0.001). In patients with cervical herniated disc a reduction of pain was observed, albeit not significant (Chi² = 7.02, p = 0.135). Two predictors were associated with postoperative pain in lumbar and cervical disc surgery patients: the subjective prognosis of gainful employment (p<0.001) and depression (p<0.001). Conclusion In the majority of disc surgery patients, a long-term reduction of pain was observed. Cervical surgery patients seemed to benefit less from surgery than the lumbar surgery patients. A negative subjective prognosis of gainful employment and stronger depressive symptoms were associated with postoperative pain. The findings may promote multimodal rehabilitation concepts including psychological and work-related support.

Abstract
OBJECTIVE This study aimed to determine the prognostic value of MRI variables to predict outcome in patients with herniated disc-related sciatica, and whether MRI could facilitate the decision making between early surgery and prolonged conservative care in these patients. METHODS A prospective observational evaluation of patients enrolled in a randomized trial with 1-year follow-up was completed. A total of 283 patients with sciatica who had a radiologically confirmed disc herniation were randomized either to surgery or to prolonged conservative care with surgery if needed. Outcome measures were recovery and leg pain severity. Recovery was registered on a 7-point Likert scale. Complete/near complete recovery was considered a satisfactory outcome. Leg pain severity was measured on a 0- to 100-mm visual analog scale. Multiple MRI characteristics of the degenerated disc herniation were independently scored by 3 spine experts. Cox models were used to study the influence of MRI variables on rate of recovery, and linear mixed models were used to determine the predictive value of MRI variables for leg pain severity during follow-up. The interaction of each MRI predictor with treatment allocation was tested. There were no study-specific conflicts of interest. RESULTS Baseline MRI variables associated with less leg pain severity were the reader's assessment of presence of nerve root compression (p < 0.001), and assessment of extrusion compared with protrusion of the disc herniation (p = 0.006). Both variables tended to be associated, but not significantly, with satisfactory outcome during follow-up (HR 1.45, 95% CI 0.93-2.24, and HR 1.24, 95% CI 0.96-1.61, respectively). The size of disc herniation at baseline was not associated with outcome. There was no significant change in the effects between treatment groups. CONCLUSIONS MRI assessment of the presence of nerve root compression and extrusion of a herniated disc at baseline was associated with less leg pain during 1-year follow-up, irrespective of a surgical or conservative treatment. MRI findings seem not to be helpful in determining which patients might fare better with early surgery compared with a strategy of prolonged conservative care.

Abstract
BACKGROUND Although previous studies have illustrated improvements in surgical cohorts for patients with intervertebral disc herniation, there are limited data on predictors of long-term outcomes comparing surgical and nonsurgical outcomes. QUESTIONS/PURPOSES We assessed outcomes of operative and nonoperative treatment for patients with intervertebral disc herniation and symptomatic radiculopathy at 8 years from the Spine Patient Outcomes Research Trial. We specifically examined subgroups to determine whether certain populations had a better long-term outcome with surgery or nonoperative treatment. METHODS Patients with symptomatic lumbar radiculopathy for at least 6 weeks associated with nerve root irritation or neurologic deficit on examination and a confirmed disc herniation on cross-sectional imaging were enrolled at 13 different clinical sites. Patients consenting to participate in the randomized cohort were assigned to surgical or nonoperative treatment using variable permuted block randomization stratified by site. Those who declined randomization entered the observational cohort group based on treatment preference but were otherwise treated and followed identically to the randomized cohort. Of those in the randomized cohort, 309 of 501 (62%) provided 8-year data and in the observational group 469 of 743 (63%). Patients were treated with either surgical discectomy or usual nonoperative care. By 8 years, only 148 of 245 (60%) of those randomized to surgery had undergone surgery, whereas 122 of 256 (48%) of those randomized to nonoperative treatment had undergone surgery. The primary outcome measures were SF-36 bodily pain, SF-36 physical function, and Oswestry Disability Index collected at 6 weeks, 3 months, 6 months, 12 months, and then annually. Further analysis studied the following factors to determine if any were predictive of long-term outcomes: sex, herniation location, depression, smoking, work status, other joint problems, herniation level, herniation type, and duration of symptoms. RESULTS The intent-to-treat analysis of the randomized cohort at 8 years showed no difference between surgical and nonoperative treatment for the primary outcome measures. Secondary outcome measures of sciatica bothersomeness, leg pain, satisfaction with symptoms, and self-rated improvement showed greater improvement in the group randomized to surgery despite high levels of crossover. The as-treated analysis of the combined randomized and observational cohorts, adjusted for potential confounders, showed advantages for surgery for all primary outcome measures; however, this has the potential for confounding from other unrecognized variables. Smokers and patients with depression or comorbid joint problems had worse functional outcomes overall (with surgery and nonoperative care) but similar surgical treatment effects. Patients with sequestered fragments, symptom duration greater than 6 months, those with higher levels of low back pain, or who were neither working nor disabled at baseline showed greater surgical treatment effects. CONCLUSIONS The intent-to-treat analysis, which is complicated by high rates of crossover, showed no difference over 8 years for primary outcomes of overall pain, physical function, and back-related disability but did show small advantages for secondary outcomes of sciatica bothersomeness, satisfaction with symptoms, and self-rated improvement. Subgroup analyses identified those groups with sequestered fragments on MRI, higher levels of baseline back pain accompanying radiculopathy, a longer duration of symptoms, and those who were neither working nor disabled at baseline with a greater relative advantage from surgery at 8 years. LEVEL OF EVIDENCE Level II, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND CONTEXT Percutaneous laser disc decompression (PLDD) is a minimally invasive treatment for lumbar disc herniation, with Food and Drug Administration approval since 1991. However, no randomized trial comparing PLDD to conventional treatment has been performed. PURPOSE In this trial, we assessed the effectiveness of a strategy of PLDD as compared with conventional surgery. STUDY DESIGN/SETTING This randomized prospective trial with a noninferiority design was carried out in two academic and six teaching hospitals in the Netherlands according to an intent-to-treat protocol with full institutional review board approval. PATIENT SAMPLE One hundred fifteen eligible surgical candidates, with sciatica from a disc herniation smaller than one-third of the spinal canal, were included. OUTCOME MEASURES The main outcome measures for this trial were the Roland-Morris Disability Questionnaire for sciatica, visual analog scores for back and leg pain, and the patient's report of perceived recovery. METHODS Patients were randomly allocated to PLDD (n=57) or conventional surgery (n=58). Blinding was impossible because of the nature of the interventions. This study was funded by the Healthcare Insurance Board of the Netherlands. RESULTS The primary outcome, Roland-Morris Disability Questionnaire, showed noninferiority of PLDD at 8 (-0.1; [95% confidence interval (CI), -2.3 to 2.1]) and 52 weeks (-1.1; 95% CI, -3.4 to 1.1) compared with conventional surgery. There was, however, a higher speed of recovery in favor of conventional surgery (hazard ratio, 0.64 [95% CI, 0.42-0.97]). The number of reoperations was significantly less in the conventional surgery group (38% vs. 16%). Overall, a strategy of PLDD, with delayed surgery if needed, resulted in noninferior outcomes at 1 year. CONCLUSIONS At 1 year, a strategy of PLDD, followed by surgery if needed, resulted in noninferior outcomes compared with surgery.

Abstract
At times lumbar disc herniations present a quandary to the spine surgeon in regards to the most appropriate intervention and a need to optimize medical and surgical therapies. We discuss a case of ours and our experience in treating this common spinal pathology, along with a commentary on the article published by Kim et al. entitled 'Spontaneous regression of extruded lumbar disc herniation: three cases report in Korean J Spine. 2013 Jun;10(2):78-81.'

Abstract
Study Design A retrospective cohort study. Objectives To determine the outcome and any differences in the clinical results of three different surgical methods for lumbar disk herniation and to assess the effect of factors that could predict the outcome of surgery. Methods We evaluated 148 patients who had operations for lumbar disk herniation from March 2006 to March 2011 using three different surgical techniques (laminectomy, microscopically assisted percutaneous nucleotomy, and spinous process osteotomy) by using Japanese Orthopaedic Association (JOA) Back Pain Evaluation Questionnaire, Resumption of Activities of Daily Living scale and changes of visual analog scale (VAS) for low back pain and radicular pain. Our study questionnaire addressed patient subjective satisfaction with the operation, residual complaints, and job resumption. Data were analyzed with SPSS version 16.0 (SPSS, Inc., Chicago, Illinois, United States). Statistical significance was set at 0.05. For statistical analysis, chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and repeated measure analysis were performed. For determining the confounding factors, univariate analysis by chi-square test was used and followed by logistic regression analysis. Results Ninety-four percent of our patients were satisfied with the results of their surgeries. VAS documented an overall 93.3% success rate for reduction of radicular pain. Laminectomy resulted in better outcome in terms of JOA Back Pain Evaluation Questionnaire. The outcome of surgery did not significantly differ by age, sex, level of education, preoperative VAS for back, preoperative VAS for radicular pain, return to previous job, or level of herniation. Conclusion Surgery for lumbar disk herniation is effective in reducing radicular pain (93.4%). All three surgical approaches resulted in significant decrease in preoperative radicular pain and low back pain, but intergroup variation in the outcome was not achieved. As indicated by JOA Back Pain Evaluation Questionnaire-Low Back Pain (JOABPQ-LBP) and lumbar function functional scores, laminectomy achieved significantly better outcome compared with other methods. It is worth mentioning that relief of radicular pain was associated with subjective satisfaction with the surgery among our study population. Predictive factors for ineffective surgical treatment for lumbar disk herniation were female sex and negative preoperative straight leg raising. Age, level of education, and preoperative VAS for low back pain were other factors that showed prediction power.

Global Spine J 2014; 4:279-86.

Abstract
Study Design Literature review. Objective Since the 1970s, spine surgeons have commonly required 6 weeks of failed conservative treatment prior to considering surgical intervention for various spinal pathologies. It is unclear, however, if this standard has been validated in the literature. The authors review the natural history, outcomes, and cost-effectiveness studies relating to the current standard of 6 weeks of nonoperative care prior to surgery for patients with spinal pathologies. Methods A systematic Medline search from 1953 to 2013 was performed to identify natural history, outcomes, and cost-effectiveness studies relating to the optimal period of conservative management prior to surgical intervention for both cervical and lumbar radiculopathy. Demographic information, operative indications, and clinical outcomes are reviewed for each study. Results A total of 5,719 studies were identified; of these, 13 studies were selected for inclusion. Natural history studies demonstrated that 88% of patients with cervical radiculopathy and 70% of patients with lumbar radiculopathy showed improvement within 4 weeks following onset of symptoms. Outcomes and cost-effectiveness studies supported surgical intervention within 8 weeks of symptom onset for both cervical and lumbar radiculopathy. Conclusions There are limited studies supporting any optimal duration of conservative treatment prior to surgery for cervical and lumbar radiculopathy. Therefore, evidence-based conclusions cannot be made. Based on the available literature, we suggest that an optimal timing for surgery following cervical radiculopathy is within 8 weeks of onset of symptoms. A shorter period of 4 weeks may be appropriate based on natural history studies. Additionally, we found that optimal timing for surgery following lumbar radiculopathy is between 4 and 8 weeks. A prospective study is needed to explicitly identify the optimal duration of conservative therapy prior to surgery so that costs may be reduced and patient outcomes improved.

Abstract
Herniation of nucleus pulposus leading to leg pain is the commonest indication for lumbar spine surgery. However, there is no consensus when to stop conservative treatment and when to consider for surgery. A systematic review of literature was done to find a consensus on the issue of when should surgery be performed for herniation of nucleus pulposus in lumbar spine was conducted. Electronic database searches of Medline, Embase and Pubmed Central were performed to find articles relating to optimum time to operate in patients with herniation of nucleus pulposus in lumbar spine, published between January 1975 and 10 December 2012. The studies were independently screened by two reviewers. Disagreements between reviewers were settled at a consensus meeting. A scoring system based on research design, number of patients at final followup, percentage of patients at final followup, duration of followup, journal impact factor and annual citation index was devised to give weightage to Categorize (A, B or C) each of the articles. Twenty one studies fulfilled the criteria. Six studies were of retrospective design, 13 studies were of Prospective design and two studies were randomized controlled trials. The studies were categorized as: Two articles in category A (highest level of evidence), 12 articles in category B (moderate level of evidence) while seven articles in Category C (poor level of evidence). Category A studies conclude that duration of sciatica prior to surgery made no difference to the outcome of surgery in patients with herniation of nucleus pulposus in the lumbar spine. Ten out of 12 studies in Category B revealed that longer duration of sciatica before surgery leads to poor results while 2 studies conclude that duration of sciatica makes no difference to outcome. In category C, five studies conclude that longer duration of sciatica before surgery leads to poor outcome while two studies find no difference in outcome with regards to duration of sciatica. A qualitative and quantitative analysis was performed which favoured the consensus that longer duration of sciatica leads to poorer outcome. A systematic and critical review of literature revealed that long duration of preoperative leg pain lead to poor outcome for herniation of nucleus pulposus. Only a broad time frame (2-12 months) could be derived from the review of literature due to lack of high quality studies and variable and contrasting results of the existing studies. While surgery performed within six months was most commonly found to lead to good outcome of surgery, further studies are needed to prove this more conclusively. At this stage it is felt that time alone should not be the basis of recommending surgery and multiple other variables should be considered in a shared decision making process between the surgeon and the patient.

Comparison of early and late percutaneous endoscopic lumbar discectomy for lumbar disc herniation. Acta Neurochir (Wien) 2013; 155:1931-6. [PMID: 23975645 DOI: 10.1007/s00701-013-1828-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2013] [Accepted: 07/19/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND The optimal timing for percutaneous endoscopic lumbar discectomy (PELD) in cases of lumbar disc herniation (LDH) is debatable. This retrospective study sought to determine which category of PELD surgical intervention time resulted in greater improvement in clinical outcomes. METHODS We retrospectively reviewed the medical records of 145 patients who underwent PELD for single-level LDH. The patients were divided into three categories according to the duration of leg pain before surgery, the early and late group being symptomatic for ≤3 months and >3 months, ≤6 months and >6 months, ≤12 months and >12 months. Surgical time, blood loss, postoperative hospital stay, hospitalization cost, rates of reoperation due to surgical failure, Macnab criteria assessment, visual analogue scale (VAS) of back pain, leg pain and numbness, Japanese orthopedic association low back pain score (JOA) before and after surgery were compared. RESULTS No significant differences were found between the early and late groups according to different categories in patients' demographics, surgical time, blood loss, preoperative and postoperative VAS (lower-back pain, leg pain and numbness) scores, JOA scores and distribution of Macnab criteria assessment. Early PELD surgical intervention did not result in greater improvement of clinical outcomes. Later surgical intervention resulted in about one-third surgical failure rates for patients being symptomatic for >6 months (≤6 months, 11/96, 11.5 %; >6 months, 2/49, 4.1 %; P = 0.245) and >12 months (≤12 months, 12/120, 10.0 %; >12 months, 1/25, 4.0 %; P = 0.568) of the early surgical intervention groups. Significant difference was observed between the comorbidities and non-comorbidities group in the rate of reoperation (P = 0.040). CONCLUSIONS Early PELD surgical intervention did not result in greater improvement of clinical outcomes for patients with lumbar disc herniation. Later surgical intervention resulted in less failure rates for patients than the early surgical intervention groups. PELD performed when the leg pain before surgery being symptomatic for >6 months may be good for avoiding surgical failure and reducing the duration of leg pain.

Abstract
STUDY DESIGN Questionnaire survey. OBJECTIVE To explore spine surgeons' attitudes toward the involvement of nonphysician clinicians (NPCs) to screen patients with low back or low back-related leg pain referred for surgical assessment. SUMMARY OF BACKGROUND DATA Although the utilization of physician assistants is common in several healthcare systems, the attitude of spine surgeons toward the independent assessment of patients by NPCs remains uncertain. METHODS We administered a 28-item survey to all 101 surgeon members of the Canadian Spine Society, which inquired about demographic variables, patient screening efficiency, typical wait times for both assessment and surgery, important components of low back-related complaints history and examination, indicators for assessment by a surgeon, and attitudes toward the use of NPCs to screen patients with low back and leg pain referred for elective surgical assessment. RESULTS Eighty-five spine surgeons completed our survey, for a response rate of 84.1%. Most respondents (77.6%) were interested in working with an NPC to screen patients with low back-related complaints referred for elective surgical assessment. Perception of suboptimal wait time for consultation and poor screening efficiency for surgical candidates were associated with greater surgeon interest in an NPC model of care. We achieved majority consensus regarding the core components for a low back-related complaints history and examination, and findings that would support surgical assessment. A majority of respondents (75.3%) agreed that they would be comfortable not assessing patients with low back-related complaints referred to their practice if indications for surgery were ruled out by an NPC. CONCLUSION The majority of Canadian spine surgeons were open to an NPC model of care to assess and triage nonurgent or emergent low back-related complaints. Clinical trials to establish the effectiveness and acceptance of an NPC model of care by all stakeholders are urgently needed.

Abstract
OBJECTIVES The objective of this study was to determine if the available literature answers the following questions: does percutaneous disc decompression using Dekompressor device relieve radicular pain caused by a small disc herniation? Is the duration of response stable and clinically worthwhile? Is relief of pain corroborated by improvements in physical and social function? Does relief of pain result in reduction in the use of other health care? Is there a risk of serious side effects or complications? DESIGN/SETTINGS: The study was designed as a narrative review and description of the available evidence, drawn from the databases of PubMed, EMBASE, and the Cochrane Library. Innovatively, the concept of the "context of the patient" was introduced in the assessment. It required the assessors to consider the alternatives the patients and their treating practitioners faced. RESULTS The literature search identified three nonrandomized clinical trials, and a single case series. All studies were reasonably rigorous in reporting relief of pain and the use of analgesics. Evidence with respect to physical functioning was scarce. Although investigators reported on the relief of pain, they lacked rigor when reporting associated outcome measures such as use of other health care and physical functioning. CONCLUSIONS Unfortunately, the context of a patient with persistent radicular pain caused by a small disc herniation is the lack of good alternatives to Dekompressor procedure. The moral question is whether Dekompressor is any less valid an option than perpetual opioids or discectomy. This question would be much easier to answer if the literature on Dekompressor was more rigorous and more compelling in its evidence.

Abstract
BACKGROUND The purpose of the present study was to determine if the duration of symptoms affects outcomes following the treatment of intervertebral lumbar disc herniation. METHODS An as-treated analysis was performed on patients enrolled in the Spine Patient Outcomes Research Trial (SPORT) for the treatment of intervertebral lumbar disc herniation. Randomized and observational cohorts were combined. A comparison was made between patients who had had symptoms for six months or less (n = 927) and those who had had symptoms for more than six months (n = 265). Primary and secondary outcomes were measured at baseline and at regular follow-up intervals up to four years. The treatment effect for each outcome measure was determined at each follow-up period for the duration of symptoms for both groups. RESULTS At all follow-up intervals, the primary outcome measures were significantly worse in patients who had had symptoms for more than six months prior to treatment, regardless of whether the treatment was operative or nonoperative. When the values at the time of the four-year follow-up were compared with the baseline values, patients in the operative treatment group who had had symptoms for six months or less had a greater increase in the bodily pain domain of the Short Form-36 (SF-36) (mean change, 48.3 compared with 41.9; p < 0.001), a greater increase in the physical function domain of the SF-36 (mean change, 47.7 compared with 41.2; p < 0.001), and a greater decrease in the Oswestry Disability Index score (mean change, -41.1 compared with -34.6; p < 0.001) as compared with those who had had symptoms for more than six months (with higher scores indicating less severe symptoms on the SF-36 and indicating more severe symptoms on the Oswestry Disability Index). When the values at the time of the four-year follow-up were compared with the baseline values, patients in the nonoperative treatment group who had had symptoms for six months or less had a greater increase in the bodily pain domain of the SF-36 (mean change, 31.8 compared with 21.4; p < 0.001), a greater increase in the physical function domain of the SF-36 (mean change, 29.5 compared with 22.6; p = 0.015), and a greater decrease in the Oswestry Disability Index score (mean change, -24.9 compared with -18.5; p = 0.006) as compared with those who had had symptoms for more than six months. Differences in treatment effect between the two groups related to the duration of symptoms were not significant. CONCLUSIONS Increased symptom duration due to lumbar disc herniation is related to worse outcomes following both operative and nonoperative treatment. The relative increased benefit of surgery compared with nonoperative treatment was not dependent on the duration of the symptoms.

Abstract
Abstract
BACKGROUND:
Outcome of lumbar disc herniation is often based on clinical scores and less frequently on the neurological examination. However, even when clinical outcome measures are favorable, patients may still experience motor or sensory impairment.
OBJECTIVE:
To evaluate the percentage of patients with persistent neurological deficits after lumbar disc surgery and whether these correlate with clinical outcome.
METHODS:
A total of 150 patients with sciatica and lumbar disc herniation with neurological impairment underwent microdiscectomy and were prospectively followed for 24 months. Patients were assessed pre- and postoperatively with neurological examination, the Oswestry Disability Index (ODI), and the visual analog scale (VAS) for pain.
RESULTS:
Twenty-four months after surgery, 25% of patients who presented with motor deficits, 40% of patients with sensory deficits, and 48% of patients with reflex abnormalities remained unchanged. The VAS and the ODI showed significant improvement in both patients with and without persistent neurological impairment immediately after surgical repair of the herniated disc with progressive improvement over the follow-up period. However, when calculating the area under the receiver operating characteristics curve, no statistically significant correlation could be established between the presence and persistence of neurological impairment and the 2 clinical scores.
CONCLUSION:
There seems to be no correlation between clinical results and neurological impairment when assessed by the VAS and ODI.

Abstract
BACKGROUND The optimal timing for surgical intervention in cases of lumbar disc herniation is debatable. This retrospective study sought to determine whether early surgical intervention resulted in greater improvement in clinical outcomes. METHODS A total of 46 patients with lumbar disc herniation treated by microendoscopic discectomy were reviewed. Surgery was performed when leg pain persisted despite adequate conservative treatment. The patients were divided into two groups according to the duration of symptoms before surgery, the early group being symptomatic for <or=3 months and the late group for >3 months. Surgical time, blood loss, severity of back pain, leg pain and numbness (visual analogue scale, or VAS), and a patient-oriented evaluation score (Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, or JOABPEQ) before and after surgery were compared. The JOABPEQ is a new evaluation method for lumbar spinal disorders based on Roland-Morris disability questionnaires and Short Form 36. RESULTS There were 23 patients in each group. No significant differences were found between the groups in patients' demographics (age, sex, type of herniation), surgical time, blood loss, or pre- and postoperative VAS (lower-back pain, leg pain, numbness). There were no significant differences between the groups in the scores for the five subscales - pain-related disorders, gait disturbance, lumbar spine dysfunction, social life disturbance, psychological disorders - of the preoperative JOABPEQ. Postoperative scores for psychological disorders improved significantly (P < 0.05) in the late group (mean score 39.9) compared to the early group (mean score 22.1). Interestingly, no significant difference of improvement in the scores other than psychological disorder was found between the two groups. CONCLUSIONS Early surgical intervention did not result in greater improvement of clinical outcomes for patients with lumbar disc herniation. Later surgical intervention resulted in significant improvement of psychological disorders.
