Endoscopic Lumbar Disc Surgery Experience with the TESSYS Technique in 253 Case Series. J Clin Med 2024; 13:1911. [PMID: 38610676 PMCID: PMC11012553 DOI: 10.3390/jcm13071911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 03/17/2024] [Accepted: 03/21/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Herniated lumbar disc (HLD) is a widespread medical problem which can require surgery. Minimally invasive surgical management can represent an extremely valuable option for patients suffering from HLDs. Transforaminal endoscopic lumbar discectomy is an alternative to classical microdiscectomy which was proposed more than two decades ago and has evolved technologically with time. Methods: The transforaminal endoscopic spine system (TESSYS) technique has been introduced in recent years and offers the advantage of performing a controlled foraminal augmentation with full nerve root protection. We started using this technique in 2016 and prospectively evaluated the results of endoscopic TESSYS-based operations performed in a three-year period until the end of 2019. Selection criteria were very strict, and we included only patients with unilateral radicular pain with no instability who failed conservative therapy. Out of the 253 patients operated on in that time span, 183 were available for follow-up evaluation. Results: After surgery, there was a clinically significant improvement of all symptoms which basically lasted in the long-term follow-up. Complications were limited and generally minor. Redo surgery with microdiscectomy was required only in four cases. Obesity did not play a clear negative role in patients' outcome. Conclusions: Endoscopic transforaminal discectomy with the TESSYS technique represents a valuable management option for patients harbouring unilateral herniated lumbar disc located laterally.

Abstract
STUDY DESIGN Case control study. OBJECTIVE Micro-lumbar discectomy or Interbody fusion procedure are work-horse surgical procedures in management of lumbar disc disease. Spine surgeon in their early years of practice gets confused in choosing ideal surgical plan when dealing with a complex scenario. A clinical score is needed to guide spine surgeons in choosing an optimal surgical plan. MATERIALS AND METHODS Study was done with research grant approval from AO Spine. A predictive score was formulated as per hypothesis following a pilot study. Two fellowship trained spine surgeons-one using the score (Group A) and other not using score (Group B-control) treated 40 patients included in their respective group. All patients were analysed preoperatively, post-surgery at 12 months follow-up with Visual analog scale score for back pain, leg pain, Oswestry disability index score, SF-36 score. Change in parameters at 12 months follow-up were analysed statistically. P ≤ .05 was considered statistically significant. Success rate of individual surgeon who managed respective group of patients and Difficulty index of surgeon who managed without using score was evaluated at 12 months follow-up. RESULTS Success rate of Group A-surgeon was higher than Group B-surgeon .15% of Group B patients had poor surgical outcome at follow-up. Statistically significant improvement in Group A patients were seen in all 3 evaluated parameters when compared to Group B patients at 12 months of follow-up (P ≤ .05). Difficulty index of surgeon who didn't use the score was 15%. CONCLUSION The proposed predictive score comprising all risk factors, can be used by spine surgeons when they are confronted with difficult scenario in decision-making. Accuracy, reliability and validity of the score needs to be evaluated in a larger scale. LEVEL OF EVIDENCE Ⅲ.

Minimally Invasive Far Lateral Lumbar Discectomy With Modified Technique: Symptomatic Relief and Intersegmental Stability Study. Cureus 2024; 16:e53415. [PMID: 38435187 PMCID: PMC10908426 DOI: 10.7759/cureus.53415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/01/2024] [Indexed: 03/05/2024] Open
Abstract
OBJECTIVE To evaluate the use of a modified minimally invasive surgery (MIS) technique for far lateral lumbar discectomy (FLDH) that minimizes the degree of bony drilling required for nerve root decompression, increasing postoperative pain reduction rate with reduced risk of iatrogenic spinal instability. SUMMARY OF BACKGROUND DATA FLDH accounts for approximately 10% of all lumbar disc herniations and is increasingly recognized in the era of advanced imaging techniques. These disc herniations typically result in extra-foraminal nerve root compression. Minimally invasive spine techniques are increasingly performed with various degrees of foraminal and facet removal to decompress the affected nerve root. METHODS The study design involves a single institutional, retrospective cohort technical review. The review was completed of all patients undergoing MIS far lateral lumbar discectomy between 2010 and 2020. Cross-sectional, summary statistics were calculated for all variables. Counts and percentages were recorded for categorical variables and mean and standard deviations were calculated for continuous variables. RESULTS A total of 48 patients underwent MIS far lateral lumbar discectomies (FLLD) from 2010 to 2020. The mean age was 63 ± 11.5 years (60.4% males), the mean BMI was 28.5 ± 5.5, and 20.8% smokers. The most common presenting complaint was both low back and radicular pain (79.2%) with 8.3% of patients suffering from motor weakness preoperatively. The mean follow-up time was 4.3 ± 2.7. The mean length of stay was 1.3 ± 1.4 days with 77.1% of patients discharged postoperative day one. Forty-three patients (93.5%) had improvement in their symptoms. Twenty-seven (58.7%) had complete resolution in 2.6 months on average. Six patients (13%) had immediate symptom resolution postoperatively. CONCLUSIONS Our modified technique for FLLD allows MIS access to the extra-foraminal site of nerve root compression without the need for bony drilling. This minimizes postoperative pain and reduces the risk of iatrogenic spinal instability without sacrificing symptom resolution.

Abstract
STUDY DESIGN Meta-analysis. OBJECTIVES This study aimed to summarize the clinical efficacy and safety of the various annular defect repair methods that have emerged in recent years. METHODS A meta-analysis of randomized and non-randomized controlled trials was conducted. Articles from PubMed, Embase, and the Cochrane Library (CENTRAL) on Lumbar disc herniation treatment with annular repair published from inception to April 2, 2022 were included. We summarized the clinical efficacy and safety of annular repair techniques based on a random-effects model meta-analysis. RESULTS 7 randomized controlled studies and 8 observational studies with a total of 2161 participants met the inclusion criteria. The pooled data analysis showed that adding the annular repair technique reduced postoperative recurrence rate, reoperation rate, and loss of intervertebral height compared with lumbar discectomy alone. Subgroup analysis based on different annular repair techniques showed that the Barricaid Annular Closure Device (ACD) was effective in preventing re-protrusion and reducing reoperation rates, while there was no significant difference between the other subgroups. The annulus fibrosus suture (AFS) did not improve the postoperative Oswestry Disability Index (ODI). No statistically significant difference was observed in the incidence of adverse events between the annular repair and control groups. CONCLUSIONS Lumbar discectomy combined with ACD can effectively reduce postoperative recurrence and reoperation rates in patients with LDH. AFS alone was less effective in reducing recurrence and reoperation rates and did not improve postoperative pain and function.

Abstract
STUDY DESIGN Prospective Study. OBJECTIVES There are numerous techniques for performing lumbar discectomy, each with its own rationale and stated benefits. The authors set out to evaluate and compare the perioperative variables, results, and complications of each treatment in a group of patients provided by ten hospitals and operated on by experienced surgeons. METHODS This prospective study comprised of 591 patients operated between February-2017 to February-2019. The procedures included open discectomy, microdiscectomy, tubular microdiscectomy, interlaminar endoscopic lumbar discectomy, transforaminal endoscopic lumbar discectomy and Destandau techniques with a follow-up of minimum 2 years. VAS (Visual Analogue Score) for back and leg pain, ODI (Oswestry Disability Index), duration of surgery, hospital stay, length of scar, operative blood loss and peri-operative complications were recorded in each group. RESULTS Post-operatively, there was a significant improvement in the VAS score for back pain as well as leg pain, and ODI scores spanning all groups, with no significant distinction amongst them. When compared to open procedures (open discectomy and microdiscectomy), minimally invasive surgeries (tubular discectomy, interlaminar endoscopic lumbar discectomy, transforaminal endoscopic lumbar discectomy, and Destandau techniques) reported shorter operative time, duration of hospital stays, better cosmesis, and lower blood loss. Overall, the complication rate was reported to be 8.62%. Complication rates differed slightly across approaches. CONCLUSION Minimally invasive surgeries have citable advantages over open approaches in terms of perioperative variables. However, all approaches are successful and provide comparable pain relief with similar functional outcomes at long term follow up.

Abstract
Introduction Nearly one million patients in the United States undergo spine surgical procedures annually to seek relief from chronic back and neck pain. A multidisciplinary approach is key to ensuring the efficiency and safety of the surgical process, with the anesthesia team, nursing, surgeon, and healthcare facilities all playing a role. The purpose of this study is to capture potential associations between the anesthesiologists' case volume and patient postoperative outcomes in the early recovery period. Methods A retrospective review of anterior cervical discectomy and fusion (ACDF), lumbar decompression (LD), and lumbar fusion (LF) patients from July 2019 to June 2023 was performed. Anesthesiologists were categorized into low, medium, and high volumes of spine surgical cases. Univariate analysis was performed on patient demographics, intraoperative measures, post-anesthesia care unit (PACU) measures, and postoperative measures by anesthesiologist volume. Results This study included 545 ACDF, 815 LD, and 1,144 LF patients. There were no differences between groups in ACDF patients by anesthesiologist volume. When examining patients undergoing LD, there was a difference in patients with an American Society of Anesthesiologists (ASA) physical status classification of three or greater (low volume: 41.7% vs. medium volume: 53.7% vs. high volume: 45.0%; p=0.029). When examining patients undergoing LF, there were differences in patients with low temperatures in PACU (low volume: 2.8% vs. medium volume: 7.3% vs. high volume: 4.2%; p=0.044) and the percentage of patients with a 90-day emergency department return (low volume: 7.7% vs. medium volume: 11.9% vs. high volume: 7.0%; p=0.024). Conclusion While this study found a minimal impact of anesthesiologist volume on postoperative outcomes, recent literature has emphasized the critical role of teamwork and specialized surgical teams to enhance efficiency and patient care. Further studies are warranted to identify other variables in anesthesia, nursing, and surgical team workflow that may impact postoperative outcomes in spinal surgeries.

Lumbar Discectomy With Bone-Anchored Annular Closure Device in Patients With Large Annular Defects: One-Year Results. Cureus 2023; 15:e40195. [PMID: 37325689 PMCID: PMC10263173 DOI: 10.7759/cureus.40195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/09/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND Reherniation rates following lumbar discectomy are low for most patients; however, patients with a large defect in the annulus fibrosis have a significantly higher risk of recurrence. Previous results from a randomized controlled trial (RCT) demonstrated that the implantation of a bone-anchored annular closure device (ACD) during discectomy surgery lowered the risk of symptomatic reherniation and reoperation over one year with fewer serious adverse events (SAEs) compared to discectomy alone. OBJECTIVE The objective of this prospective, post-market, historically controlled study was to evaluate the use of an ACD during discectomy, and to confirm the results of the RCT that was used to establish regulatory approval in the United States. METHODS In this post-market study, all patients (N = 55) received discectomy surgery with a bone-anchored ACD. The comparison population was patients enrolled in the RCT study who had discectomy with an ACD (N = 262) or discectomy alone (N = 272). All other eligibility criteria, surgical technique, device characteristics, and follow-up methodology were comparable between studies. Endpoints included rate of symptomatic reherniation or reoperation, SAEs, and patient-reported measures of disability, pain, and quality of life. RESULTS Fifty-five patients received ACD implants at 12 sites between May 2020 and February 2021. In the previous RCT, 272 control patients had discectomy surgery alone (RCT-Control), and 262 patients had discectomy surgery with an ACD implant (RCT-ACD). Baseline characteristics across groups were typical of the overall population undergoing lumbar discectomy. The proportion of patients who experienced reherniation and/or reoperation was significantly lower in the ACD group compared to RCT-ACD and RCT-Control groups (p < 0.05). In the ACD study, the one-year rate of symptomatic reherniation was 3.7%, compared to 8.5% in the RCT-ACD group and 17.0% in the RCT-Control group. In the ACD group, the risk of reoperation was 5.5%, compared to 6.5% in the RCT-ACD group and 12.5% in the RCT-Control group. There were no device-related SAEs or device integrity failures in the ACD, and there were clinically meaningful improvements in patient-reported measures of disability, pain, and quality of life. CONCLUSION In this post-market study of bone-anchored ACD in patients with large annular defects, rates of symptomatic reherniation, reoperation, and SAEs were all low. Compared to the RCT, the post-market ACD study demonstrated lower rates of reherniation and/or reoperation and measures of back pain one-year post-surgery.

Modified lumbar foraminoplasty using a power-aided reciprocating burr for percutaneous transforaminal endoscopic lumbar discectomy: A technical note and clinical report. Front Surg 2023; 9:1091187. [PMID: 36684228 PMCID: PMC9849748 DOI: 10.3389/fsurg.2022.1091187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Accepted: 12/08/2022] [Indexed: 01/06/2023] Open
Abstract
Background One of the main difficulties in a transforaminal endoscopic lumbar discectomy (TELD), and simultaneously the most critical step, is performing an effective and safe foraminoplasty, which is especially difficult for beginners. To make it safer and faster for beginners to perform, we have used a specially designed power-aided reciprocating burr for TELD and reported the technical details. Methods From Jan. 2019 to Nov. 2022, 432 patients with single-level, symptomatic L4/5 or L5/S1 disc herniation were treated with TELD using a novel power-aided reciprocating burr. The surgical procedure is described in detail. Magnetic resonance imaging (MRI) was performed the following day and 3 months after the operation. The learning curves of surgeons with different seniority levels are displayed. The Visual Analogue Scale (VAS) score and the Oswestry Disability Index (ODI) were used to measure low back pain, leg pain, and lumbar function. All patients were followed up for at least 1 year. Results All patients underwent endoscopic surgery successfully. Among the 432 patients, radicular outer membrane damage was observed in 6 cases, and 1 case had hernia of the nerve tract. Except for this patient with aggravation of postoperative numbness, the postoperative neurological symptoms of all patients were significantly improved. The mean VAS scores for low back pain and leg pain and ODI scores were significantly decreased 6 w post-operatively and were maintained until 12 months post-operatively compared to preoperative scores (P < 0.05). All three doctors involved in the study had substantial experience in traditional open spinal surgery. The more operations all three surgeons completed, the more time spent on intervertebral foraminoplasty decreased (P < 0.05). Among them, doctors without experience in TELD surgery became proficient in this technique after accumulating experience in 13 cases. There was no significant difference in foraminoplasty time among these three surgeons during the same growing period (P > 0.05). Conclusions Current clinical data demonstrated the safety and efficacy of modified TELD using a power-aided reciprocating burr for treating lumbar disc herniation (LDH) and showed that this technique significantly reduces the learning curve for beginners when performing foraminoplasty.

Abstract
INTRODUCTION Postoperative discal pseudocyst (PDP) is rare. Few studies have reported on the recurrence of PDPs, and there is a lack of understanding of their clinical features and treatment methods. This study discusses the clinical characteristics and treatment of recurrent PDPs. PATIENT CONCERNS A 25-year-old man presented with radiating pain and numbness in the lateral left calf and dorsum of the foot. DIAGNOSIS Postoperative discal pseudocyst. INTERVENTIONS He underwent lumbar discectomy, which provided immediate postoperative relief. However, the symptoms recurred 45 days later. Magnetic resonance imaging (MRI) showed a lesion compressing the dura and nerve roots at the site of the previous surgery. The lesion appeared hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging. The patient was treated conservatively for 1 month without significant relief. He then underwent lumbar discectomy and cyst removal, which immediately relieved his symptoms. However, 27 days later, the patient again developed the same symptoms. MRI examination showed recurrence of PDP. As 1 month of conservative treatment failed to relieve the patient's symptoms, we performed posterior instrumented lumbar fusion and cyst removal. OUTCOMES The patient's symptoms disappeared, and have not recurred for 1 year at the time of writing. CONCLUSIONS PDP is a rare complication of lumbar discectomy. Repeat lumbar discectomy can effectively treat PDP, but the cyst can recur. We, for the first time, used posterior instrumented lumbar fusion to successfully treat recurrent PDP.

Postoperative pain treatment after lumbar discectomy. A protocol for a systematic review with meta-analysis and trial sequential analysis. Acta Anaesthesiol Scand 2022; 66:288-294. [PMID: 34811726 DOI: 10.1111/aas.14000] [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: 11/02/2021] [Accepted: 11/06/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Patients undergoing lumbar discectomy usually suffer from moderate to severe pain during the postoperative period. Multimodal, or balanced analgesia, is the leading treatment principle for managing postoperative pain. The rationale is to achieve optimal pain treatment through additive or synergistic effects of several non-opioid analgesics, and thereby, reducing the need for postoperative opioids, facilitating early mobilization and functional rehabilitation. For discectomy surgery, evidence of both the benefit and harm of different analgesic interventions is unclear. OBJECTIVES This systematic review aims to investigate the benefits and harms of analgesic interventions in adult patients after lumbar discectomy. METHODS This protocol for a systematic review is written according to The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. We will search The Cochrane Library's CENTRAL, PubMed, EMBASE, and ClinicalTrails.gov for published and ongoing trials. All randomized clinical trials assessing the postoperative analgesics effect of an intervention with a control or no-intervention group undergoing lumbar discectomy will be included. Two authors will independently screen trials for inclusion using Covidence, extract data and assess the risk of bias using Cochrane's risk-of-bias 2 tool. We will analyse the data using Review Manager and Trial Sequential Analysis. Meta-analysis will be performed according to the Cochrane guidelines. We will present our primary findings in a 'summary of findings' table and evaluate the overall certainty of evidence using the GRADE approach. DISCUSSION This systematic review will assess the benefits and harms of analgesic interventions after lumbar discectomy and have the potential to improve best practices and advance research.

Abstract
Introduction Lumbar discectomy is a common and effective treatment for symptomatic disk herniation. It has been suggested that lumbar discectomy in older patients may result in poorer clinical outcomes and lesser satisfaction. The purpose of this study was to assess age-related difference in patient reported outcomes of patients undergoing lumbar discectomy for chronic low back and radicular pain. Materials and methods Patients with chronic lumbar radiculopathy without neurological deficit underwent non-urgent single level lumbar discectomy in our institution between 2014 and 2017. Pain level (using VAS score), Oswestry Disability Index, and SF-12 scores were retrospectively reviewed and compared between younger patients (<60 years, group 1) and older patients (>60 years, group 2). Results Seventy-three patients, aged between 34–76 years participated in this study. VAS, ODI, and SF-12 scores improved significantly after the surgery for each group (P < .01). When comparing between the groups, no significant differences in the outcomes measured were found after the surgery in both early post-operative follow-up and late post-operative follow-up (P > .05). Discussion Elderly patients undergoing lumbar discectomy report a significant reduction in VAS, ODI, and SF-12 scores justifying the procedure. Conclusion Lumbar discectomy improved function and decreased pain level to similar extent in both younger and older patients suffering from radicular symptoms related to lumbar disc herniation.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To determine the rate of early failures (readmission or reoperation for new or recurrent pain/neurological symptoms) within 30 days after lumbar discectomy and identify associated risk factors. METHODS A retrospective cohort study was conducted of patients undergoing lumbar discectomy in the National Surgical Quality Improvement Program database between 2013 and 2017. Rates of readmission for new or recurrent symptoms or reoperation for revision discectomy or fusion within 30 days postoperatively were measured and correlated with risk factors. RESULTS In total 62 690 patients were identified; overall rate of readmission within 30 days was 3.3%, including 1.2% for pain or neurological symptoms. Populations at increased risk of readmission were those with 3 or more levels of treatment (2.0%, odds ratio [OR] 2.8%, P < .01), age >70 years (1.8%, OR 1.6, P < .01), class 3 obesity (1.5%, OR 1.4, P = .04), and female gender (1.4%, OR 1.2, P = .02). The overall rate of reoperation within 30 days was 2.2%, including 1.2% for revision decompression or lumbar fusion surgery. Populations at increased risk of reoperation were revision discectomies (1.4%, OR 1.7, P < .01) and females (1.1%, OR 1.4, P < 0.01). Extraforaminal discectomies were associated with lower rates of readmission (0.7%, OR 0.6, P = 0.02) and reoperation (0.4%, OR 0.4, P = .01). CONCLUSIONS Early failures after lumbar discectomy surgery are rare. However, certain subpopulations are associated with increased rates of early failure: obesity, multilevel surgery, females, and revision discectomies.

Abstract
OBJECTIVE The role of spine surgeons in precipitating and mediating sustained prescription opioid use remains controversial at this time. The purpose of this study was to identify prescription opioid use following lumbar discectomy and characterize the source of opioid prescriptions by clinician specialty (surgeon vs nonsurgeon). METHODS Using a retrospective review, the authors identified adult patients undergoing lumbar discectomy for a primary diagnosis of disc herniation between 2010 and 2017. The primary outcome was sustained prescription opioid use, defined as issue of an opioid prescription at a time point 90 days or longer after the surgical procedure. The primary predictor variable was prescriber specialty (surgeon vs nonsurgeon). The independent effect of provider specialty on the number of opioid prescriptions issued to patients was assessed using multivariable Poisson regression that accounted for confounding from all other clinical and sociodemographic variables. RESULTS This study included 622 patients who underwent a lumbar discectomy. A total of 610 opioid prescriptions were dispensed for this population after surgery. In total, 126 patients (20.3%) had at least one opioid prescription in the period beyond 90 days following their surgery. The majority of opioid prescriptions, 494 of 610 (81%), were non-inpatient prescriptions. Among these, only a minority (26%) of outpatient opioid prescriptions were written by surgical providers. Following multivariable Poisson regression analysis, surgical providers were found to have a lower likelihood of issuing an opioid prescription compared to nonsurgical clinicians (incidence rate ratio [IRR] 0.78; 95% CI 0.68-0.89; p = 0.001). CONCLUSIONS A minority of lumbar discectomy patients continue to receive opioid prescriptions up to 15 months after surgery. Many of these prescriptions are written by nonsurgical providers unaffiliated with the operative team.

Abstract
Introduction The most common degenerative abnormality of the lumbar spine is lumbar disc herniation. There are two options of treatment, i.e. medical and surgical. Due to the scarcity of literature, it is a need of the hour to further study and evaluate the benefits and efficacy of early surgical intervention versus conservative management of lumbar disc herniation. Methods This study was conducted in the neurology unit of a tertiary care hospital in Pakistan from April 2019 to March 2021. After obtaining informed consent, 250 patients with a lumbar disc herniation, between the ages of 20 and 50 years, were enrolled in the study. Out of them, 81 participants chose surgical intervention while 169 participants chose medical intervention. Before the intervention, the patient’s pain score was noted on the visual analog scale (VAS). The pain was assessed again 14 days after surgical intervention and 90 days after the start of medical intervention. Results There was a significant difference in the pain score in the post-intervention period in both the medical (7.01 ± 1.05 vs. 3.54 ± 0.51; p-value: <0.0001) and surgical intervention groups (6.92 ± 0.95 vs. 2.41 ± 0.42; p-value: <0.0001). Post-intervention, the VAS pain score was significantly lower in the surgical group as compared to the medical group (2.41 ± 0.42 vs. 3.54 ± 0.51; p-value: <0.0001). Conclusion In this study, there was a significant decline in pain in both groups; however, the reduction was more significant in the surgical group. Patients should be given both options for management of lumbar disc herniation and should be explained the pros and cons of each treatment option.

Abstract
UNLABELLED Vascular injury during lumbar disc surgery was first reported as a complication in 1945 by Linton and White [32]. Injuries of the major blood vessels located anteriorly to the spine in the retroperitoneal space are rare but occur suddenly and are life-threatening. The authors present anatomo-topographical background of this complication, standards of diagnostic process and treatment on the base of literature as well the surgical and endovascular management of this complication. The authors performed a literature search for reported iatrogenic vascular injuries due to lumbar disc surgery. We were able to find 10 case series and 17 single case reports describing this rare but serious lumbar disc surgeryrelated complication. Overall, there were 159 patients who developed vascular injury due to lumbar disc surgery. The surgical exploration and repair has been done in 116 patients. In last decades due to rapid development of endovascular techniques this complication was repaired endovascular techniques in 21 patients. The most common lumbar level which resulted in iatrogenic vascular injury was L4-L5. There were reported 66 deaths and in 83 patients the postoperative period was uneventful. CONCLUSIONS We would like to highlight the occurrence of this complication and introduction of rapid management to prevent the fatal outcome. Lumbar disc surgery is one of the most often performed procedures in neurosurgical wards. The awareness of this life-threatening complication should be known to all members of an operative team. The knowledge of proper management of this serious adverse event may save a patient's life.

Abstract
UNLABELLED Damage to large abdominal vessels during lumbar discectomy surgery is a rare but life-threatening complication. A CASE REPORT The authors present the case of a 57-year-old patient who received surgery for critical degenerative lumbal spinal stenosis on the L4-L5 level. The diagnosis was based on strong right sciatica and neurogenic claudication. A bilateral laminotomy from the right and a microdiscectomy were performed. During surgery, no bleeding from the intervertebral space was observed and blood pressure was low but stable from the beginning. After surgery, the patient was in good general and neurological condition, without preoperative right-sided sciatica. Within a few hours after the operation, the circulatory and respiratory systems were stable with normal saturation and the patient did not report shortness of breath. Paleness of the skin and mucous membranes was observed. Follow-up morphology tests performed at 6 and 10.5 hours after surgery showed a decrease in the level of erythrocytes. The patient had palpable tenderness in the left hypochondriac region. Suspicion of bleeding into the abdominal cavity from arteries or iliac veins was stated. Immediately, an angio-computed tomography (CT) of the abdominal cavity was performed, which confirmed the presence of a hematoma in the peritoneal space and a pseudoaneurysm of the left iliac artery. The patient was urgently transported to the Vascular Surgery Clinic, where a Y-type covered stent was implanted percutaneously into both iliac arteries. After the procedure, there were symptoms of ischaemia in the left lower extremity and intermittent claudication. A Doppler study showed signs of narrowing at the stent level on the left side. The patient was reoperated after a CT check-up and a second stent was implanted into the left iliac artery, which allowed vasodilation and true flow in the artery. CONCLUSIONS The authors suggest that both the neurosurgeon and anaesthesiologist should have been aware of the possibility of such a rare but life-threatening complication as iliac vessel damage during lumbar discectomy surgery. A quick diagnosis and implementation of a proper procedure reduces the high mortality rate caused by this complication. In cases of a sudden unjustified drop in blood pressure during lumbar discectomy, an immediate laparotomy should be performed to find and repair the site of laceration of a vessel. In patients who are stable hemodynamically, performing an angio-CT function of the abdominal cavity is suggested and the damaged artery should be treated with a covered stent.

Abstract
In recent years, enhanced recovery after surgery (ERAS) has been widely used in spine surgery and achieved satisfactory results. In order to standardize the ERAS implementation process and application in percutaneous endoscopic interlaminar lumbar decompression/discectomy (PEID), we reviewed the literatures and cited evidence-based medicine data, and had a national comprehensive discussion among experts of the Group of Minimally Invasive Spinal Surgery and Enhanced Recovery, Professional Committee of Orthopedic Surgery and Enhanced Recovery, Association of China Rehabilitation Technology Transformation and Promotion. Altogether, the up-to-date expert consensus have been achieved. The consensus may provide the reference for clinical treatment in aspect of the standardization of surgical operations, the reduction of surgical trauma and complications, the optimization of perioperative pain and sleep management, the prevention of venous thrombosis, and the guidance of patients' functional training and perioperative education.

Abstract
BACKGROUND An annulus fissure or defect will inevitably be left on the posterior annulus fibrosus after almost all kinds of lumbar discectomy, which may lead to unsatisfying postoperative pain relief and recurrence of the disc herniation. OBJECTIVE The objective of this research is to introduce the technique of full-endoscopic annulus fibrosus suture following lumbar discectomy through the transforaminal or interlaminar approach, and to analyze the clinical outcome of full-endoscopic lumbar discectomy and annulus fibrosus suture. STUDY DESIGN This study used a prospective cohort design. SETTING The research was conducted in a hospital and outpatient surgery center. METHODS A total of 50 patients with noncontained lumbar disc herniation treated with full-endoscopic lumbar discectomy and annulus fibrosus suture were treated in our department between January 2018 and November 2018. Full-endoscopic single-stitch suture via the transforaminal approach (Group T) or double-stitch suture via the interlaminar approach (Group I) was selected according to the level of lesion. Lumbar magnetic resonance imaging (MRI) was reexamined on the second day and 3 months after operation to evaluate the completeness of the discectomy and the adequacy of nerve decompression. Patients were followed up on the second day, 3 months, 6 months, and one year after operation to evaluate the relief of low back pain and leg pain, using a visual analog scale (VAS, 100-point scale). At 3 months, 6 months, and one year after operation, the patients were followed up for recovery of lumbar spine function, using the Oswestry Disability Index (ODI). At the one-year follow-up, the MacNab score was used to evaluate the clinical outcome, and the recovery of nerve root function (sensation, muscle strength, and reflex) was recorded. RESULTS All operations were successfully completed, including 27 cases in Group T and 23 cases in Group I. There were no surgical complications and no recurrence of lumbar disc herniation. Lumbar MRI reexaminations of all patients showed that the herniated disc was completely removed and the nerves were fully decompressed. Postoperative low back pain and leg pain were significantly relieved, and the ODI score was significantly improved (P < .01) in both groups. At the one-year follow-up, the excellent and good rates as measured by the MacNab score were 92.6% in Group T and 91.3% in Group I with no significant difference between the 2 groups (P > .05). The impaired sensation and muscle strength in the low extremities of evolved nerve root of the 2 groups of patients recovered significantly at the one-year follow-up (P < .01), but the tendon reflex did not recover significantly (P > .05). LIMITATIONS This is an observational cohort study with relatively small sample sizes and short-term follow-up. CONCLUSIONS Full-endoscopic lumbar discectomy and annulus fibrosus suture through either the transforaminal or interlaminar approach are safe and effective minimally invasive spinal surgery techniques that can reduce the recurrence rate of lumbar disc herniation after full-endoscopic lumbar discectomy.

Abstract
Introduction: Patients with lumbar disc herniation and associated sciatica are often referred for lumbar discectomy. The surgical defect in the annulus fibrosus is typically left unrepaired after lumbar discectomy. Patients with large postsurgical annular defects (≥6 mm width) have a higher risk of symptom recurrence and reoperation compared to those with small defects. In these high-risk patients, a treatment gap exists due to the lack of effective treatments for durable annulus fibrosus repair.Areas covered: This article highlights the therapeutic need and summarizes the clinical results of a bone-anchored annular closure device (Barricaid) that was designed to fill the treatment gap in patients with large postsurgical annular defects. Clinical results were summarized by means of a systematic review with meta-analysis of two randomized and two nonrandomized controlled studies.Expert opinion: Professional societal recommendations and clinical study results support the adoption of bone-anchored annular closure for use in properly selected patients undergoing lumbar discectomy who are at high-risk for reherniation due to a large postsurgical defect in the annulus fibrosus. The risks of symptomatic reherniation and reoperation are approximately 50% lower in patients treated with lumbar discectomy and the Barricaid device compared to lumbar discectomy only, representing a clinically effective treatment strategy.

Abstract
Objective Vertebral endplate disruptions (VEPD) are common findings on imaging after lumbar surgery. The objective of this study was to explore the clinical implications of VEPD development following lumbar discectomy with or without implant with a bone-anchored annular closure device (ACD). Methods This was a multicenter randomized controlled trial of patients with large postsurgical annular defects after limited lumbar discectomy who were randomized to additionally receive an ACD or no additional treatment. VEPD were identified on computed tomography and confirmed by an imaging core laboratory. Clinical outcomes included recurrent herniation, reoperation, Oswestry Disability Index, leg pain, and back pain. Patient follow-up in this study was 3 years. Results In the ACD group (n=272), the risk of reoperation was lower in patients with vs without VEPD (8% vs 24%, p<0.01), but no other clinical outcomes differed when stratified by VEPD prevalence or size. In the Control group (n=278), the risk of symptomatic reherniation was higher in patients with VEPD (41% vs 23%, p<0.01) and patients with the largest VEPD had the highest reoperation rates. Patient-reported outcomes were not associated with VEPD prevalence or size in the Control group. Conclusion VEPD had no significant influence on patient-reported outcomes at 3 years after lumbar discectomy. VEPD increased the risk of recurrence in patients treated with lumbar discectomy only, but had no negative influence in patients treated with the ACD.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To investigate the association between lumbar epidural steroid injection (LESI) and incidental durotomy (ID) in patients with a diagnosis of disc herniation undergoing a primary discectomy. METHODS A Medicare patient database was queried for patients between the ages of 65 and 85 years who underwent a primary lumbar discectomy for a diagnosis of lumbar disc herniation or degeneration from 2008 to 2014. Our main cohort of 64 849 patients was then divided into 2 groups: patients who experienced a dural tear (N = 2369) and our matched (age, gender, and history of diabetes) control cohort of patients who did not (N = 62 480). All patients who had a history of LESI were further identified and stratified into 4 subgroups by duration between LESI and discectomy (<3 months, 3-6 months, 6 months to 1 year, and overall), and a comparison of the relative incidence of ID was made among these subgroups. A multivariate logistic regression analysis was employed to determine the relationship between LESI and ID. RESULTS Overall incidence of ID was 3.7%. There was a significant difference in incidence of LESI (27.1% vs 35.0%, P < .001) between our control and ID groups. An adjusted odds ratio (OR) showed that prior LESI within 3 to 6 months (OR 1.47, 95% CI 1.20-1.81, P < .001) and within less than 3 months (OR 1.46, 95% CI 1.24-1.72, P < .001) of surgery were significantly associated with ID. CONCLUSION LESI increases the risk of ID in patients who undergo a subsequent lumbar discectomy within 6 months of injection.

Abstract
BACKGROUND The risk of recurrent herniation after lumbar discectomy is highest during the first postoperative year. The purpose of this study was to determine whether implantation of a bone-anchored annular closure device (ACD) following limited lumbar discectomy reduced the risk of recurrent herniation and complications during the first year of follow-up compared to limited lumbar discectomy alone (Controls) and whether this risk was influenced by patient characteristics. METHODS In this randomized multicenter trial, patients with symptomatic lumbar disc herniation and with a large annular defect following limited lumbar discectomy were randomized to bone-anchored ACD or Control groups. The risks of symptomatic reherniation, reoperation, and device- or procedure-related serious adverse events were reported over 1 year of follow-up. RESULTS Among 554 patients (ACD 276; Control 278), 94% returned for 1-year follow-up. Bone-anchored ACD resulted in lower risks of symptomatic reherniation (8.4% vs. 17.3%, P = .002) and reoperation (6.7% vs. 12.9%, P = .015) versus Controls. Device- or procedure-related serious adverse events through 1 year were reported in 7.1% of ACD patients and 13.9% of Controls (P = .009). No baseline patient characteristic significantly influenced these risks. CONCLUSIONS Among patients with large annular defects following limited lumbar discectomy, additional implantation with a bone-anchored ACD lowered the risk of symptomatic reherniation and reoperation over 1 year follow-up. Device- or procedure-related serious adverse events occurred less frequently in the ACD group. These conclusions were not influenced by patient characteristics. ClinicalTrials.gov (NCT01283438).

Abstract
Objective To determine whether implanting an annular closure device (ACD) following a lumbar discectomy procedure in patients with large defects in the annulus fibrosus lowers the risk of reoperation after 4 years. Methods In a multicenter randomized trial, patients with large annular defects following single-level lumbar discectomy were intraoperatively randomized to additionally receive an ACD or no treatment (Controls). Clinical and imaging follow-up were performed at routine intervals over 4 years of follow-up. Main outcomes included reoperations at the treated lumbar level, leg pain scores on a visual analog scale, Oswestry Disability Index (ODI), and Physical Component Summary (PCS) and Mental Component Summary (MCS) scores from the SF-36 questionnaire. Results Among 550 patients (ACD 272, Control 278), the risk of reoperation over 4 years was 14.4% with ACD and 21.1% with Controls (P=0.03). The reduction in reoperation risk with ACD was not significantly influenced by patient age (P=0.51), sex (P=0.34), body mass index (P=0.21), smoking status (P=0.85), level of herniation (P=0.26), leg pain severity at baseline (P=0.90), or ODI at baseline (P=0.54). All patient-reported outcomes improved in each group from baseline to 4 years (all P<0.001). The percentage of patients who achieved the minimal clinically important difference without a reoperation was proportionally higher in the ACD group compared to Controls for leg pain (P=0.07), ODI (P=0.10), PCS (P=0.02), and MCS (P=0.06). Conclusion The addition of a bone-anchored ACD following lumbar discectomy in patients with large post-surgical annular defects reduces the risk of reoperation and provides better long-term pain and disability relief over 4 years compared to lumbar discectomy only.

Abstract
STUDY DESIGN Case Report. BACKGROUND AND PURPOSE The use of pain neuroscience education (PNE) is indicated when there are psychosocial contributions to a person's pain experience. The scientific literature has established the efficacy of the use of PNE in a population with chronic pain but there is a paucity of evidence to support the use of PNE in athletic populations. The purpose of this case report is to describe the use of PNE and graded exposure exercises specific to an athlete returning to Olympic weightlifting. CASE DESCRIPTION The patient underwent an L5-S1 discectomy to resolve paresthesia in his leg, completed a bout of post-operative rehabilitation but returned 15 months after the surgery. He presented with the chief complaint of low back tightness and fear of lumbar flexion. When asked to touch his toes during the lumbar flexion range of motion examination, he demonstrated aberrant lumbar movement by hinging at the hips with a straight back due to fear that flexing would damage his lumbar spine. The patient was seen for four weeks with a focus on PNE and graded exposure to weightlifting activities. OUTCOMES The patient returned to Olympic weightlifting and decreased his Fear Avoidance Behavior Questionnaire (FABQ) score from 22 to 4 during the course of physical therapy. His Tampa Scale of Kinesiophobia (TSK) score also decreased from 55 to 31. By discharge, he was able to bend at the lumbar spine with full flexion and no longer believed the motion to cause damage. DISCUSSION The case is unique because it describes the implementation of PNE in an athlete returning to weightlifting, and the scientific literature for use of PNE in this population is lacking. The identification of kinesiophobia and implementation of PNE and graded exposure exercises lead to an optimal outcome for this patient. LEVEL OF EVIDENCE Level 4.

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
BACKGROUND Patients with large defects in the annulus fibrosus following lumbar discectomy have high rates of symptomatic reherniation. The Barricaid annular closure device provides durable occlusion of the annular defect and has been shown to significantly lower the risk of symptomatic reherniation in a large European randomized trial. However, the performance of the Barricaid device in a United States (US) population has not been previously reported. DESIGN AND METHODS This is a historically controlled post-market multicenter study to determine the safety and efficacy of the Barricaid device when used in addition to primary lumbar discectomy in a US population. A total of 75 patients with large annular defects will receive the Barricaid device following lumbar discectomy at up to 25 sites in the US and will return for clinical and imaging follow-up at 4 weeks, 3 months, and 1 year. Trial oversight will be provided by a data safety monitoring board and imaging studies will be read by an independent imaging core laboratory. Patients treated with the Barricaid device in a previous European randomized trial with comparable eligibility criteria, surgical procedures, and outcome measures will serve as historical controls. Main outcomes will include back pain severity, leg pain severity, Oswestry Disability Index, health utility on the EuroQol-5 Dimension questionnaire, complications, symptomatic reherniation, and reoperation. Propensity score adjustment using inverse probability of treatment weighting will be used to adjust for differences in baseline patient characteristics between the US trial participants and European historical controls. ETHICS AND DISSEMINATION This study was approved by a central institutional review board. The study results of this trial will be widely disseminated at conference proceedings and published in peer-reviewed journals. The outcomes of this study will have important clinical and economic implications for all stakeholders involved in treating patients with lumbar discectomy in the US.

Abstract
Background Postoperative discitis (POD) remains a dreaded complication in the present era of asepsis. The treatment has been traditionally conservative, but the safety of spinal implants in infective settings has prompted the surgeons to provide rigid immobilization for promoting healing. A major concern in a country like ours is huge patient inflow and long waiting list added to the woe of patient's refusal for a second operative intervention after a first undesirable outcome. Objectives The aim of the study was to evaluate the functional and radiological outcome of conservative management of POD and determine the methods of prevention. Settings and Design A retrospective case study series in a tertiary-level hospital. Materials and Methods Between January 2015 and 2017, 12 cases of POD (10 own and 2 referred) were managed and followed up clinically, radiologically, and with laboratory investigation. Two cases were managed surgically-one with kyphotic deformity and the other with discharging pus. Rest were managed conservatively with analgesics and intravenously followed by oral antibiotics. At 1-year follow-up, patient satisfaction was evaluated using the MacNab outcome assessment. Statistical Analysis The descriptive data were analyzed mainly by descriptive statistics using mean, median, standard deviation, and interquartile range. Results Mean follow-up in our series was 15.2 months. Except for two operated cases, we did not go for the invasive procedure for isolation of organism in any of our cases. The total duration of antibiotic in our series was for the mean of 7.3 weeks. Visual analog scale score returned from8 initially to baseline and at final follow-up-4 excellent, 6 good, and 2 had fair outcome. There was no adverse outcome. Conclusions The majority of POD can be managed conservatively. Surgery is reserved only for special cases. Magnetic resonance imaging is the investigation of choice for diagnosing discitis. Intraoperative use of gentamicin-mixed normal saline wash reduces the incidence of discitis.

Abstract
Background. Lower back pain (LBP) is one of the most common complaints leading to disability and work absence. This study was performed to determine the rate and contributing factors of return to work in the postoperative phase after lumbar discectomy. Methods. This cohort study was performed among 142 patients attending the orthopedics spine clinic of a teaching hospital during 2016. Initially, the demographic and occupational characteristics and Oswestry disability index (ODI) were fulfilled, and patients were followed with regard to time off, work return and type of job after surgery. Results. 113 participants (79.5%) returned to work in 3 months. Male gender, higher literacy, non-manual job, less physical activity, non-smoking, formal work agreement, lower working hours and higher income were associated with return to previous work. Also, shorter preoperative duration of LBP, longer hospital stay, lower severity of LBP, lower ODI score and poor perceived prognosis of return to work were associated with return to previous work. Conclusions. Return to work after discectomy is seen in more than two-thirds of patients and is related to factors such as pain intensity and body mass index. However, return to previous versus modified job is a multifactorial issue.

Abstract
Lumbar disc herniation (LDH) is one of the most common spinal pathologies and can be associated with debilitating pain and neurological dysfunction. Discectomy is the primary surgical intervention for LDH and is typically successful. Yet, some patients experience recurrent LDH (RLDH) after discectomy, which is associated with worse clinical outcomes and greater socioeconomic burden. Large defects in the annulus fibrosis are a significant risk factor for RLDH and present a critical treatment challenge. It is essential to identify reliable and cost-effective treatments for this at-risk population. A systematic review of the PubMed and Embase databases was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies describing the treatment of LDH patients with large annular defects. The incidence of large annular defects, measurement technique, RLDH rate, and reoperation rate were compiled and stratified by surgical technique. The risk of bias was scored for each study and for the identification of RLDH and reoperation. Study heterogeneity and pooled estimates were calculated from the included articles. Fifteen unique studies describing 2,768 subjects were included. The pooled incidence of patients with a large annular defect was 44%. The pooled incidence of RLDH and reoperation following conventional limited discectomy in this population was 10.6% and 6.0%, respectively. A more aggressive technique, subtotal discectomy, tended to have lower rates of RLDH (5.8%) and reoperation (3.8%). However, patients treated with subtotal discectomy reported greater back and leg pain associated with disc degeneration. The quality of evidence was low for subtotal discectomy as an alternative to limited discectomy. Each report had a high risk of bias and treatments were never randomized. A recent randomized controlled trial with 550 subjects examined an annular closure device (ACD) and observed significant reductions in RLDH and reoperation rates (>50% reduction). Based on the available evidence, current discectomy techniques are inadequate for patients with large annular defects, leaving a treatment gap for this high-risk population. Currently, the strongest evidence indicates that augmenting limited discectomy with an ACD can reduce RLDH and revision rates in patients with large annular defects, with a low risk of device complications.

Abstract
A 19-year-old woman developed hypotension and abdominal distension during lumbar discectomy. Computed tomography revealed a right common artery injury and a large retroperitoneal hematoma. She was transferred to our hospital and brought to an angiography room directly. Endovascular balloon occlusion of the aorta was performed by cardiologists while surgeons were preparing for surgery. With the hemodynamics stabilized, the injured artery was repaired. In such a case, closing the artery as soon as possible, whether by clamping or by balloon occlusion, is vital. The ability to respond with a “Heart Team” is essential for a small-manpower hospital to rescue a patient with a serious condition.

Abstract
Purpose Despite being an extremely successful procedure, recurrent disc herniation is one of the most common post-discectomy complications in the lumbar spine and contributes significant health care and socioeconomic costs. Patients with large annular defects are at a high risk for reherniation, but an annular closure device (ACD) has been designed to reduce reherniation risk in this population and may, in turn, help control direct health care costs after discectomy. Patients and methods This analysis examined the 90-day post-discectomy cost estimates among ACD-treated (n=272) and control (discectomy alone; n=278) patients in a randomized controlled trial (RCT). Direct medical costs were estimated based on 2017 Humana and Medicare claims. Index discectomies were assumed to occur in an outpatient (OP) setting, whereas repeat discectomies were assumed to be 60% in OP and 40% in inpatient (IP). A sensitivity analysis was performed on this assumption. The device cost was not included in the analysis in order to focus on costs in the 90-day post-operative period. Results Within 90 days of follow-up, post-operative complications occurred in 3.3% of the ACD patients and 8.6% of the control patients (P=0.01). The average 90-day cost to treat an ACD patient was $10,257 compared to $11,299 per control patient for a 80:20 distribution of Commercial:Medicare coverage ($1,042 difference). This difference varied from $687 with 100% Medicare to $1,132 with 100% Commercial coverage. Varying the IP vs OP distribution resulted in a cost difference range of $968 to $1,156 with the ACD. Conclusion Augmenting discectomy with an ACD in high-risk patients with a large annular defect reduced reherniation and reoperation rates, which translated to a reduction of direct health care costs between $687 and $1,156 per patient during the 90-day post-operative period. Large annular defect patients are an easily identifiable high-risk population. Operative strategies that reduce complication risks in these patients, such as the ACD, could be advantageous from both patient care and economic perspectives.

Abstract
BACKGROUND Low back and leg pain due to lumbar discal hernia (LDH) is an important health issue. Current evidences support surgery in carefully selected patients who have failed conservative treatment and do not exhibit any psychosocial overlay. However, as known, sometimes it may be still very difficult to normalize the life qualities of patients for long times. Now different surgical methods for LDH are in use with new technological materials. One of them is lumbar disc prosthesis. In this study, the radiological and clinical effects of using lumbar disc prosthesis were evaluated with comparing patients underwent simple lumbar microdsicectomy. The purpose of this study is to reveal whether inserting the disc prosthesis into the intervertebral distance after lumbar microdiscectomy is beneficial or not both radiologically and clinically. METHODS A total of 114 patients were analyzed; the first cohort consisted of 57 patients who received a lumbar discectomy at a single level along with the implantation of a disc prosthesis and the second consisted of 57 patients only received a lumbar discectomy at a single level. These 2 groups were studied by comparing the disc space on the level of carried out operations with pain scales, foramen diameters of coming about related roots preoperatively and postoperatively at 3 years. RESULTS One of the significant results of the implementation of the disc prosthesis is fulfilment of a healthy disc height again after microdiscectomy due to LDH. We concluded that fulfilment of a healthy disc height with lumbar disc prosthesis was clinically beneficial for patients underwent microdiscectomy. CONCLUSIONS Based on the results obtained in this study, it can be concluded that the implantation of a disc prosthesis in appropriate patients is more favorable regarding pain and spinal physiology when compared to simple microdiscectomy.

Abstract
Introduction Lumbar discectomy patients with large annular defects are at a high risk for reherniation and reoperation, which could be mitigated through the use of an annular closure device (ACD). To identify the most effective treatment pathways for this high-risk population, it is critical to understand the clinical outcomes and socioeconomic costs among reoperated patients as well as the utility of ACD for minimizing reoperation risk. Methods This was a post hoc analysis of a prospective, multicenter, randomized controlled trial (RCT) designed to investigate the safety and efficacy of an ACD. All 550 patients (both ACD treated and control) from the RCT with follow-up data through 2 years were included in this analysis (69 reoperated and 481 non-reoperated). Reoperations were defined as any revision surgery of the index level, regardless of indication. Equivalent U.S. Medicare expenditures for reoperations were estimated through cost multipliers derived from the commercially available PearlDiver database. Results A significantly greater number of control patients (45/278; 16%) compared to ACD patients (24/272; 9%) underwent a revision surgery at the index level within 2 years of followup (p=0.01). At 2 years of follow-up, the reoperated patients had significantly worse Oswestry Disability Index scores and visual analog scale for leg and back pain scores compared to their non-reoperated counterparts (p<0.0001). The total estimated direct medical costs for reoperation were US $952,348 ($13,802 per reoperated patient), with control patients accounting for the majority of this cost burden ($565,188; 59%). Conclusion Post-discectomy reoperation is associated with significantly increased patient morbidity, missed work, and direct treatment costs in a population at high risk for reherniation. Annular closure helped minimize this clinical and socioeconomic burden by reducing the incidence of reoperation by nearly 50% (16% control vs 9% ACD).

Abstract
Retrospectively study.The purpose of this study was to compare the effects of intraoperative epidural steroids and single dose intravenous steroids following a percutaneous endoscopic lumbar discectomy (PELD).Inflammatory irritation of dorsal root ganglia or sensory nerve roots may cause postoperative pain. Epidural steroids have been applied after a lumbar discectomy for more than 20 years. Epidural steroid application after a PELD is easier to perform and safer because the operations are under observation of the scope.We retrospectively reviewed the medical records of patients with lumbar intervertebral disc herniation who had undergone transforaminal PELD at our department. There are 60 patients in epidural steroid group, intravenous steroid group, and control group, respectively. Visual analog scores (VAS) and the Oswestry Disability Index (ODI) were collected. Successful pain control is defined as 50% or more reduction in back and leg pain (VAS scores).VAS scores (back and leg) and ODI showed a significant decrease in all groups when comparing pre- and postoperatively. Epidural steroid group had a significant improvement in successful pain control compared with the control group at 2 weeks of follow-up. VAS scores (leg) in the epidural steroid group showed a significant decrease compared with the intravenous steroids group at 1, 3, and 7 days after the surgery, but this difference had no statistical significance at 1, 6, and 12 months of follow-up. All groups did not show a significant difference in ODI at 1, 6, and 12 months follow-up.Epidural application of steroid has a better effect on controlling the postoperative pain of PELD in the short term. The epidural application of steroid did not show a tendency to cause infection.

Abstract
BACKGROUND Replacement of a diseased lumbar intervertebral disc with an artificial device, a procedure known as lumbar total disc replacement (LTDR), has been practiced since the 1980s. METHODS Comprehensive review of published literature germane to LTDR, but comment is restricted to high-quality evidence reporting implantation of lumbar artificial discs that have been commercially available for at least 15 years at the time of writing and which continue to be commercially available. RESULTS LTDR is shown to be a noninferior (and sometimes superior) alternative to lumbar fusion in patients with discogenic low back pain and/or radicular pain attributable to lumbar disc degenerative disease (LDDD). Further, LTDR is a motion-preserving procedure, and evidence is emerging that it may also result in risk reduction for subsequent development and/or progression of adjacent segment disease. CONCLUSIONS In spite of the substantial logistical challenges to the safe introduction of LTDR to a health care facility, the procedure continues to gain acceptance, albeit slowly. CLINICAL RELEVANCE Patients with LDDD who are considering an offer of spinal surgery can only provide valid and informed consent if they have been made aware of all reasonable surgical and nonsurgical options that may benefit them. Accordingly, and in those cases in which LTDR may have a role to play, patients under consideration for other forms of spinal surgery should be informed that this valid procedure exists.

Abstract
OBJECTIVE In this paper, the authors sought to verify whether corset adoption could improve the short-term and midterm outcome scores of patients after single-level lumbar discectomy. METHODS A monocentric, randomized controlled trial of 54 consecutive patients who underwent single-level lumbar discectomy at the authors' institution was performed from September 2014 to August 2015. Patients were randomly assigned to use or not use a lumbar corset in the upright position. Patients with previous interventions for disc herniation or with concomitant canal or foraminal stenosis were excluded. The visual analog scale, Oswestry Disability Index, and Roland Morris Disability Questionnaire were used to compare groups at the 1- and 6-month follow-up time points. RESULTS No significant differences between the 2 groups were reported at either time point for any given outcome irrespective of the scale used. CONCLUSIONS Corset adoption does not improve the short-term and midterm outcomes of patients after single-level lumbar discectomy.

Abstract
Purpose The purpose of this study was to evaluate perioperative complications of lumbar discectomy with or without bone-anchored annular closure device (ACD) implant in patients at high risk of recurrent disc herniation. Methods This was a post hoc analysis of a randomized controlled trial that compared outcomes of lumbar discectomy with or without additional placement of an ACD. Patients presented with imaging evidence of lumbar disc herniation and radicular pain that was unresponsive to conservative care. Randomization occurred intraoperatively following discectomy completion and confirmation of annular defect width ≥6 mm. Main outcomes included serious adverse events (SAEs) from any cause, device- or procedure-related SAEs, and reoperations at the index level. The perioperative period included all outcomes occurring between the day of surgery and 90 days following hospital discharge. Results Analyses were performed on a modified intention-to-treat population consisting of 272 patients treated with ACD and 278 patients treated with lumbar discectomy only (controls). Mean patient age was 44 years, 59% were men, and mean body mass index was 26 kg/m2. Baseline patient characteristics and operative outcomes were comparable between groups. The risks of all-cause SAE (9.7% vs 16.3%, p=0.056), device- or procedure-related SAE (4.5% vs 10.2%, p=0.02), and index-level reoperation (1.9% vs 5.4%, p=0.03) were lower with ACD vs controls. In multivariable logistic regression, control group assignment and female gender were independently associated with higher risk of device- or procedure-related SAE and index-level reoperation, respectively. Conclusion In patients undergoing lumbar discectomy to treat symptomatic intervertebral disc herniation, adjunctive placement of an ACD reduces the risk for perioperative complications occurring through 90 days following hospital discharge.

Abstract
The present study explored a method to reduce X-ray exposure dose and avoid targeted puncture complications in percutaneous transforaminal endoscopic lumbar discectomy (PTELD). A total of 66 patients with lumbar disc herniation were divided into two groups for a controlled study. In the experimental group, 31 patients were subjected to PTELD using a novel targeted puncture technique with application of a lumbar disc herniation target collimator. The remaining 35 patients in the control group were subjected to free-hand targeted puncture PTELD. The number of X-ray fluoroscopies performed intraoperatively, targeted puncture accuracy, visual analogue scale for surgical pain and Oswestry disability index of the two groups were statistically analyzed. The experimental and control groups exhibited a statistically significant difference in the number of X-ray fluoroscopies required during the procedure (P<0.01). The number of successful first targeted punctures was 27 (87.1%) in the experimental group and three (8.6%) in the control group, indicating that the puncture accuracy was higher in the experimental group than in the control group. As for the pain response to outer sleeve insertion (local anesthetic injection through the guide sleeve), the experimental group had 25 mild cases (80.6%), five moderate cases (16.1%) and one severe care (3.2%), whereas the control group had five mild cases (14.3%), 19 moderate cases (54.3%) and 11 severe cases (31.4%). These results demonstrated that the overall pain response of the experimental group was milder than that of control group. Due to a larger puncture deviation, the nerve root was touched by the puncture needle in 12 cases in the control group and resulted in one case of severe postoperative infection. In conclusion, the novel targeted puncture technique guided by a lumbar disc herniation target collimator outlined in the present study is able to markedly reduce X-ray exposure dose in PTELD and limit the surgical risk and pain experienced by patients. Mastering this novel puncture technique may aid those new to performing PTELD.

Abstract
STUDY DESIGN Retrospective database analysis. OBJECTIVE The impact of the 2008-2009 economic downtown on elective lumbar spine surgery is unknown. Our objective was to investigate the effect of the economic downturn on the overall trends of elective lumbar spine surgery in the United States. METHODS The Nationwide Inpatient Sample (NIS) was used in conjunction with US Census and macroeconomic data to determine historical trends. The economic downturn was defined as 2008 to 2009. Codes from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), were used in order to identify appropriate procedures. Confidence intervals were determined using subgroup analysis techniques. RESULTS From 2003 to 2012, there was a 19.8% and 26.1% decrease in the number of lumbar discectomies and laminectomies, respectively. Over the same time period, there was a 56.4% increase in the number of lumbar spinal fusions. The trend of elective lumbar spine surgeries per 100 000 persons in the US population remained consistent from 2008 to 2009. The number of procedures decreased by 4.5% from 2010 to 2011, 7.6% from 2011 to 2012, and 3.1% from 2012 to 2013. The R2 value between the number of surgeries and the S&P 500 Index was statistically significant (P ≤ .05). CONCLUSIONS The economic downturn did not affect elective lumbar fusions, which increased in total from 2003 to 2013. The relationship between the S&P 500 Index and surgical trends suggests that during recessions, individuals may utilize other means, such as insurance, to cover procedural costs and reduce out-of-pocket expenditures, accounting for no impact of the economic downturn on surgical trends. These findings can assist multiple stakeholders in better understanding the interconnectedness of macroeconomics, policy, and elective lumbar spine surgery trends.

Abstract
BACKGROUND Lumbar disc herniation is a major cause of back pain and sciatica. The surgical management of lumbar disc prolapse has evolved from exploratory laminectomy to percutaneous endoscopic discectomy. Percutaneous endoscopic discectomy is the least invasive procedure for lumbar disc prolapse. The aim of this study was to analyze the clinical outcome, quality of life, neurologic function, and complications. MATERIALS AND METHODS One hundred patients with lumbar disc prolapse who were treated with percutaneous endoscopic discectomy from May 2012 to January 2014 were included in this retrospective study. Clinical followup was done at 1 month, 3 months, 6 months, 1 year, and at yearly interval thereafter. The outcome was assessed using modified Macnab's criteria, visual analog scale, and Oswestry Disability Index. RESULTS The mean followup period was 2 years (range 18 months - 3 years). Transforaminal approach was used in 84 patients, interlaminar approach in seven patients, and combined approach in nine patients. An excellent outcome was noted in ninety patients, good outcome in six patients, fair result in two patients, and poor result in two patients. Minor complications were seen in three patients, and two patients had recurrent disc prolapse. Mean hospital stay was 1.6 days. CONCLUSIONS Percutaneous endoscopic lumbar discectomy is a safe and effective procedure in lumbar disc prolapse. It has the advantage that it can be performed on a day care basis under local anesthesia with shorter length of hospitalization and early return to work thus improving the quality of life earlier. The low complication rate makes it the future of disc surgery. Transforaminal approach alone is sufficient in majority of cases, although 16% of cases required either percutaneous interlaminar approach or combined approach. The procedure definitely has a learning curve, but it is acceptable with adequate preparations.

Abstract
OBJECT The authors' aim in this paper was to review the intraoperative use of epidural steroids in lumbar discectomy surgery with a focus on surgical complications. METHODS A comprehensive literature search was done using PubMed, MEDLINE, and the Cochrane Central Registry of Controlled Trials. Relevant papers were retrieved and analyzed. The authors performed a meta-analysis of all available data. Search terms included epidural, steroids, discectomy, lumbar disc surgery, herniated lumbar disc, methylprednisolone, and perioperative.The primary outcome was surgical complications such as wound infection or need for reoperation. Secondary outcomes were pain and postoperative narcotic usage. RESULTS Sixteen trials and 1 retrospective study (a total of 1933 patients) were eligible for inclusion in this study. In all studies, steroids were added epidurally over the nerve root before closure in cases, and control patients underwent discectomy alone. The mean age (42.7 years vs 42.4 years; RR 0.30 [95% CI -0.30 to 0.90], p = 0.32), overall complication rates (2.69% vs 1.18%; RR 1.94 [95% CI 0.72-5.26], p = 0.19), and infectious complication rates (0.94% vs 0.08%; RR 4.58 [95% CI 0.75-27.95], p = 0.10) were similar between the steroid group and control group, respectively. CONCLUSIONS There is good evidence that epidural steroids can decrease pain in the short term and decrease the usage of postoperative narcotics after lumbar spinal surgery for degenerative spinal disease. The authors' results demonstrate a trend toward increased infection with epidural steroid use, but there was not a statistically significant difference. More studies are needed to validate the long-term risk/benefit ratio of epidural steroids in lumbar discectomy.

Abstract
Technological advances in neurosurgery, aided by improvements in anesthesia have resulted in surgery that is faster, simpler and safer with excellent perioperative recovery. As a result of improved outcomes, several centers are performing certain neurosurgical procedures on an outpatient basis; where patients arrive at the hospital the morning of their procedure and leave the hospital the same evening, thus avoiding an overnight stay in the hospital. Apart from the medical benefits of the outpatient procedure, its impact on patient satisfaction is substantial. The economic benefits are extremely favorable for the patient, physician, as well as the hospital. However, due to skepticism surrounding medico-legal aspects, and how radical the concept at first sounds, these procedures have not gained widespread popularity. We provide an overview of outpatient neurosurgery discussing results, outcomes related to patients' quality of life, and impact on the economic burden on currently burgeoning health care costs.

Abstract
INTRODUCTION Knowledge about the natural clinical course is needed to improve understanding of recovery postsurgery as outcome is poor for some patients. Knowledge of the natural clinical course of symptoms and disability will inform optimal timing and the nature of rehabilitation intervention. The objective of this study is to provide first evidence synthesis investigating the natural clinical course of disability and pain in patients aged >16 years post primary lumbar discectomy. METHODS AND ANALYSIS A systematic review and data synthesis will be conducted. Prospective cohorts that include a well-defined inception cohort (point of surgery) of adult participants who have undergone primary lumbar discectomy/microdiscectomy will be included. Outcomes will include measurements reported on 1 or more outcomes of disability and pain, with a baseline presurgery measurement. Following development of the search strategy, 2 reviewers will independently search information sources, assess identified studies for inclusion, extract data and assess risk of bias. A third reviewer will mediate on any disagreement at each stage. The search will employ sensitive topic-based strategies designed for each database from inception to 31 January 2016. There will be no language or geographical restrictions. Risk of bias will be assessed using a modified QUality In Prognostic Studies (QUIPS) tool . Data will be extracted for time points where follow-up was at least 80%. Means and 95% CIs will be plotted over time for pain and disability. All results will be reported in the context of study quality. ETHICS AND DISSEMINATION This review will provide the first rigorous summary of the course of pain and disability across all published prospective cohorts. The findings will inform our understanding of when to offer and how to optimise rehabilitation following surgery. Results will be published in an open access journal. The study raises no ethical issues. PROSPERO REGISTRATION NUMBER CRD42015020806.

Abstract
BACKGROUND The purpose of this study was to determine the use of Central Epidural Steroid Injections (ESI) and Selective Nerve Root Blocks (SNRB) along with the crossover rate to lumbar discectomy in patients with a lumbar disc herniation using retrospective records database search. Butterman et al found a crossover rate for patients with symptomatic disc herniations treated with ESI of 54% (27/50), while Riew similarly found a 53% (29/55) crossover patients receiving SNRB. METHODS The database was searched in a sequential Boolean style for patients with the diagnosis of a lumbar disc herniation (Displaced Lumbar Disc - 722.1) and a SNRB (64483) or ESI (62311) who subsequently underwent a Lumbar Discectomy (63030) over a three year time period from January 2004 through December 2006. Statistical analysis was preformed examining the impact of injection type, age, location, gender, and year. RESULTS Of 482,893 patients with the diagnosis of a disc herniation, 27,799(5.76%) underwent a lumbar discectomy. The 29,941 patients who received at least one SNRB for a disc herniation, 10.80% later underwent a lumbar discectomy. The 41,420 patients who received at least one ESI for a disc herniation 9.34% later underwent a lumbar discectomy. There was a noted increase in injection procedures, particularly SNRB during the study with a greater than 50% increase. CONCLUSIONS Our examination found a much smaller, but similar crossover rate to surgery between both injection methods, which argues against one method being more effective than another in avoiding surgery. It is likely that patients are receiving these procedures more frequently during the course of conservative treatment for a disc herniation. LEVEL OF EVIDENCE This was a Level III study.

Abstract
INTRODUCTION The inpatient length of stay for lumbar discectomy has been steadily declining, since its original description over 80 years ago. The operation was first described as a day case procedure in 1987, but only sporadically since then, especially in the UK. We describe our initial experience in introducing this service in Manchester. METHODS Over a 2-year period, 50 of 80 patients undergoing lumbar discectomy met the inclusion criteria for day case surgery, using standard microscopic techniques and admission via a day case unit. RESULTS Majority (N = 48) were single level, unilateral discectomies and 36 (72%) were discharged home the same day. The remainder (28%) were discharged after an overnight stay and within 24 h. Reasons for this included post-operative back pain and hypotension. Majority (N = 47), reported improvement or resolution of pre-operative back and leg pain, which was quantified using Visual analogue scores (p < 0.01). CONCLUSIONS Lumbar microdiscectomy as a day case procedure remains a feasible and safe option in selected patients and can help free up in patient beds with a significant economic benefit also.

Retrolisthesis and lumbar disc herniation: a postoperative assessment of patient function. Spine J 2013; 13:367-72. [PMID: 23201024 PMCID: PMC3733236 DOI: 10.1016/j.spinee.2012.10.017] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2011] [Revised: 03/14/2012] [Accepted: 10/13/2012] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT The presence of retrolisthesis has been associated with the degenerative changes of the lumbar spine. However, retrolisthesis in patients with L5-S1 disc herniation has not been shown to have a significant relationship with worse baseline pain or function. Whether it can affect the outcomes after discectomy, is yet to be established. PURPOSE The purpose of this study was to determine the relationship between retrolisthesis (alone or in combination with other degenerative conditions) and postoperative low back pain, physical function, and quality of life. This study was intended to be a follow-up to a previous investigation that looked at the preoperative assessment of patient function in those with retrolisthesis and lumbar disc herniation. STUDY DESIGN Cross-sectional study. PATIENT SAMPLE Patients enrolled in SPORT (Spine Patient Outcomes Research Trial) who had undergone L5-S1 discectomy and had a complete magnetic resonance imaging scan available for review (n=125). Individuals with anterolisthesis were excluded. OUTCOME MEASURES Time-weighted averages over 4 years for the Short Form (SF)-36 bodily pain scale, SF-36 physical function scale, Oswestry Disability Index (ODI), and Sciatica Bothersomeness Index (SBI). METHODS Retrolisthesis was defined as a posterior subluxation of 8% or more. Disc degeneration was defined as any loss of disc signal on T2 imaging. Modic changes were graded 1 to 3 and collectively classified as vertebral end plate degenerative changes. The presence of facet arthropathy and ligamentum flavum hypertrophy was classified jointly as posterior degenerative changes. Longitudinal regression models were used to compare the time-weighted outcomes over 4 years. RESULTS Patients with retrolisthesis did significantly worse with regard to bodily pain and physical function over 4 years. However, there were no significant differences in terms of ODI or SBI. Similarly, retrolisthesis was not a significant factor in the operative time, blood loss, lengths of stay, complications, rate of additional spine surgeries, or recurrent disc herniations. Disc degeneration, modic changes, and posterior degenerative changes did not affect the outcomes. CONCLUSIONS Although retrolisthesis in patients with L5-S1 disc herniation did not affect the baseline pain or function, postoperative outcomes appeared to be somewhat worse. It is possible that the contribution of pain or dysfunction related to retrolisthesis became more evident after removal of the disc herniation.

Abstract
Despite low back pain being common in pregnancy, cauda equina syndrome is rare. Misdiagnosis and delay in treatment may cause neurological sequelae including urinary and fecal incontinence, sexual dysfunction in patients. A case of cauda equina syndrome in a pregnant woman at 25-week gestation is presented here. The patient underwent an emergency, standard lumbar microdiscectomy under general anesthesia on prone position. Neither the patient nor the baby had any complication related to surgery.

Abstract
BACKGROUND The established protocols of treatment of postoperative lumbar discitis have not been validated till date. We report a retrospective analysis of a series of patients with discitis following single level lumbar discectomy. We analyzed the outcome of conservative treatment of postoperative discitis with the objective to define when and what surgery was required when the conservative treatment failed. MATERIALS AND METHODS A total of 17 cases of postoperative discitis treated from 2002 to 2009 were followed up and evaluated clinically, radiologically and by laboratory investigations. All the patients were treated initially conservatively with rest and antibiotic therapy after diagnosis and those who did not respond to conservative treatment of at least 4 weeks were treated surgically. The cases were followed up with serial C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), X-ray, computed tomography (CT) scan and magnetic resonance imaging (MRI) for at least 1 year. RESULTS The mean followup was 40.38 months (range 12-86 months). Four cases failed to respond to conservative therapy and were treated surgically. In three of these four cases, open debridement, transpedicular fixation and posterolateral fusion was performed, and in the fourth case percutaneous transpedicular fixation was done. In the former group, one case was diagnosed to be tubercular, in another case Staphylococcus aureus was cultured where as the third case culture was sterile. All operated patients showed evidence of interbody fusion at 1 year followup. CONCLUSIONS Early detection and aggressive treatment are paramount in managing postoperative discitis and the majority do well with conservative treatment. Surgical management in the form of transpedicular fixation and debridement, when required, gives excellent results.

Retrolisthesis and lumbar disc herniation: a preoperative assessment of patient function. Spine J 2007; 7:406-13. [PMID: 17630138 PMCID: PMC2278018 DOI: 10.1016/j.spinee.2006.08.011] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2006] [Accepted: 08/15/2006] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Retrolisthesis is relatively rare but when present has been associated with increased back pain and impaired back function. Neither the prevalence of this condition in individuals with lumbar disc herniations nor its possible relation to preoperative back pain and dysfunction has been well studied. PURPOSE The purposes of this study were as follows: (1) to determine the prevalence of retrolisthesis (alone or in combination with other degenerative conditions) in individuals with confirmed L5-S1 disc herniation who later underwent lumbar discectomy; (2) to determine if there is any association between retrolisthesis and degenerative changes within the same vertebral motion segment; and (3) to determine the relation between retrolisthesis (alone or in combination with other degenerative conditions) and preoperative low back pain, physical function, and quality of life. STUDY DESIGN/SETTING Cross-sectional study. PATIENT SAMPLE A total of 125 individuals were identified for incorporation into this study. All patients had confirmed L5-S1 disc herniation on magnetic resonance imaging (MRI) and later underwent L5-S1 discectomy. All patients were enrolled in the Spine Patient Outcomes Research Trial (SPORT) study; data were obtained from the multi-institutional database comprised of SPORT patients from across the United States. OUTCOME MEASURES Retrolisthesis, degenerative change on MRI, and Modic changes. METHODS MRI scans of the lumbar spine were assessed at spinal level L5-S1 for all 125 patients. Retrolisthesis was defined as posterior subluxation of 8% or more. Disc degeneration was defined as any loss of disc signal on T2 imaging. Modic changes were graded 1 to 3 and collectively classified as vertebral endplate degenerative changes. The presence of facet arthropathy and ligamentum flavum hypertrophy was classified jointly as posterior degenerative changes. RESULTS The overall incidence of retrolisthesis at L5-S1 in our study was 23.2%. Retrolisthesis combined with posterior degenerative changes, degenerative disc disease, or vertebral endplate changes had incidences of 4.8%, 16%, and 4.8% respectively. The prevalence of retrolisthesis did not vary by sex, age, race, smoking status, or education level when compared with individuals with normal sagittal alignment. However, individuals with retrolisthesis were more likely to be receiving workers' compensation than those without retrolisthesis. Increased age was found to be associated with individuals having vertebral endplate degenerative changes (both alone and in conjunction with retrolisthesis) and degenerative disc disease. Individuals who had retrolisthesis with concomitant vertebral endplate degenerative changes were more often smokers and had no insurance. The presence of retrolisthesis was not associated with an increased incidence of having degenerative disc disease, posterior degenerative changes, or vertebral endplate changes. No statistical significance was found between the presence of retrolisthesis on the degree of patient preoperative low back pain and physical function. Patients with degenerative disc disease were found to have increased leg pain compared with those patients without degenerative disc changes. CONCLUSIONS We found no significant relationship between retrolisthesis in patients with L5-S1 disc herniation and worse baseline pain or function. It is possible that the contribution of pain or dysfunction related to retrolisthesis was far overshadowed by the presence of symptoms caused by the concomitant disc herniation. It remains to be seen whether retrolisthesis will affect outcome after discectomy in these patients.

The risk of "getting worse" after lumbar microdiscectomy. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2005; 14:49-54. [PMID: 15138862 PMCID: PMC3476683 DOI: 10.1007/s00586-004-0721-5] [Citation(s) in RCA: 38] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2003] [Revised: 03/10/2004] [Accepted: 03/15/2004] [Indexed: 10/26/2022]
Abstract
A frequent concern among patients operated for lumbar disc herniation is the risk of "getting worse". To give an evidence-based estimate of the risk for worsening has been difficult, since previous studies have been more focused on unfavourable outcome in general, rather than on deterioration in particular. In this prospective study of 180 patients, we report the frequency of and the risk factors for getting worse after first time lumbar microdiscectomy. Follow-up time was 12 months. Primary outcome measure was the Oswestry disability index, assessing functional status and health-related quality of life. Of the patients 4% got worse. Independent risk factors of deterioration were a long duration of sick leave and a better functional status and quality of life prior to operation. We conclude that the risk of deterioration is small, but larger if the patient has been unable to work despite relatively small health problems. This study also demonstrates that changes in instrument scores should be reported, so that an accurate failure rate can be assessed.
