Zileli M, Oertel J, Sharif S, Zygourakis C. Lumbar disc herniation: Prevention and treatment of recurrence: WFNS spine committee recommendations. World Neurosurg X 2024; 22:100275. [PMID: 38385057 PMCID: PMC10878111 DOI: 10.1016/j.wnsx.2024.100275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 02/01/2024] [Indexed: 02/23/2024] Open
Abstract
Objective This review aims to formulate the most current evidence-based recommendations on the epidemiology, prevention, and treatment of recurrent lumbar disc herniation (LDH). Methods We performed a systematic literature search in PubMed, Medline, and Google Scholar databases from 2012 to 2022 using the keywords "lumbar disc recurrence." Screening criteria resulted in 57 papers, which were summarized and presented at two international consensus meetings of the World Federation of Neurosurgical Societies (WFNS) Spine Committee. The 57 papers covered the following topics: (1) Definition and incidence of recurrence after lumbar disc surgery; (2) Prediction of recurrence before primary surgery; (3) Prevention of recurrence by surgical measures; (4) Prevention of recurrence by postoperative measures; (5) Treatment options for recurrent disc herniation; (6) The outcomes of recurrent disc herniation surgery. We utilized the Delphi method and voted on eight final consensus statements. Results and conclusion Recurrence after disc herniation surgery may be considered a surgical complication, its incidence is approximately 5% and is different from overall re-operation incidence. There are multiple risk factors predicting LDH recurrence, including smoking, younger age, male gender, obesity, diabetes, disc degeneration, and presence of lumbosacral transitional vertebrae. The level of lumbar discectomy surgery and the amount of disc material removed do not correlate with recurrence rate. Minimally invasive discectomies may have higher recurrence rates, especially during the surgeon's learning period. However, the experience of the surgeon is not related to recurrence. High-quality studies are needed to determine if activity restriction, weight loss, smoking cessation, and muscle-strengthening exercises after primary surgery can help prevent recurrence of LDH.The best treatment option for recurrent disc herniation is still being discussed. While complications of minimally invasive techniques may be lower than open discectomy, outcomes are similar. Fusion should only be considered when spinal instability and/or spinal deformity are present. Clinical outcomes and patient satisfaction after recurrent disc herniation surgery are inferior to those after initial discectomy.

Abstract
Objective To investigate and integrate multiple independent risk factors to establish a nomogram for predicting the unfavourable outcomes of percutaneous endoscopic transforaminal discectomy (PETD) for lumbar disc herniation (LDH). Methods From January 2018 to December 2019, a total of 425 patients with LDH undergoing PETD were included in this retrospective study. All patients were divided into the development and validation cohort at a ratio of 4:1. Univariate and multivariate logistic regression analyses were used to investigate the independent risk factors associated with the clinical outcomes of PETD for LDH in the development cohort, and a prediction model (nomogram) was established to predict the unfavourable outcomes of PETD for LDH. In the validation cohort, the nomogram was validated by the concordance index (C-index), calibration curve, and decision curve analysis (DCA). Results 29 of 340 patients showed unfavourable outcomes in the development cohort, and 7 of 85 patients showed unfavourable outcomes in the validation cohort. Body mass index (BMI), course of disease (COD), protrusion calcification (PC), and preoperative lumbar epidural steroid injection (LI) were independent risk factors associated with the unfavourable outcomes of PETD for LDH and were identified as predictors for the nomogram. The nomogram was validated by the validation cohort and showed high consistency (C-index = 0.674), good calibration and high clinical value. Conclusions The nomogram based on patients' preoperative clinical characteristics, including BMI, COD, LI and PC, can be used to accurately predict the unfavourable outcomes of PETD for LDH.

Posterior Dynamic Stabilization with Limited Rediscectomy for Recurrent Lumbar Disc Herniation. Pain Res Manag 2022; 2021:1288246. [PMID: 34976251 PMCID: PMC8718289 DOI: 10.1155/2021/1288246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 12/11/2021] [Accepted: 12/13/2021] [Indexed: 11/17/2022]
Abstract
Objective Recurrent lumbar disc herniation (RLDH) is the most common cause of sciatica after primary discectomy. The purpose of this study was to evaluate the efficacy of transpedicular dynamic stabilization (TDS) combined with limited rediscectomy in the treatment of single-level RLDH. Methods We retrospectively evaluated a consecutive series of 24 middle-aged patients who underwent TDS (Dynesys system) combined with limited rediscectomy (i.e., removing only extruded or loose disc fragments) for single-level Carragee type II and type IV RLDH between April 2012 and September 2017. Clinical results were evaluated with visual analog scale (VAS) for leg and low back pain, Oswestry Disability Index (ODI) scores, and complications. Imaging data include lumbar segment motion and intervertebral height. Results The mean follow-up period was 38 months. The VAS and ODI scores were significantly improved at the last follow-up. The average range of motion (ROM) at the stabilized segment was 6.4° before surgery and 4.2° at the last follow-up, with a 78.6% mean preservation (P < 0.05). Intervertebral height at the stabilized segment decreased slightly after surgery (P < 0.05). However, there was no further decline at the last follow-up. There were no cases of reherniation, screw loosening, or segmental instability. Conclusions TDS combined with limited rediscectomy resulted in an effective procedure in middle-aged patients with Carragee type II and type IV RLDH. It was able to stabilize the operated segment with partial motion preservation. Moreover, it could maintain disc height and decrease the risk of recurrence in patients with a large posterior annular defect.

Abstract
OBJECTIVE Recurrent lumbar disc herniation (rLDH) is a common issue after primary discectomy and can cause severe pain, morbidity, and reoperation. The purpose of this systematic review was to evaluate the surgical management of recurrent lumbar disc herniation. METHODS A systematic literature search was conducted using Pubmed and Embase databases on 18thAugust, 2019. The inclusion and exclusion criteria were applied according to study design, surgical approach, language, number of patients; and spinal level. Data extracted included patient demographics, and clinical outcomes (patients with excellent/good outcomes; VAS back and leg score improvement, complication and recurrence rates). RESULTS Sixteen studies, (comprising of seven prospective and nine retrospective) met the inclusion criteria. Ten studies evaluated discectomy only; four analysed fusion, and two analysed both discectomy only and fusion approaches. Fusion approaches recorded a superior success rate (8.3 % higher, p>0.05); postoperative VAS back score improvement (5 % higher, p>0.05) than discectomy alone. However, discectomy alone approaches recorded a more favourable postoperative VAS leg score improvement (4.2 % higher p>0.05), and complication rate (3.2% lower, p>0.05) than fusion techniques. CONCLUSION There is significant heterogeneity in clinical outcomes reported for studies after surgical intervention in rLDH patients. Neither discectomy nor fusion's superiority was statistically significant. Despite fusion yielding longer operative times, and length of stay (adding to the expense), it is superior in minimising mechanical instability and recurrence. Finally, we conclude that both approaches are equally efficacious in rLDH cases, and choice should be based on a case by case basis.

Abstract
Objectives The aim of this study was to investigate the long term effects of posterior lumbar interbody fusion (PLIF), applied after recurrent lumbar disc herniation (rLDH), on pain relief and clinical outcome improvement. Methods The current study is a retrospective study. We observed 22 cases from 85 patients that had undergone PLIF during February 2003 to October 2012 and all patients were followed for at least 5 years. The average age of those patients were 53 years, among them there were eight men and 14 women. Plain radiography and dynamic plain films were obtained, pre‐operation, for every patient. Magnetic resonance imaging (MRI) or computed tomography (CT) was conducted to confirm the diagnosis of rLDH before the operation. All surgeries were performed from posterior approach by the same surgeon using PLIF. Quality of life (QOL) and clinical outcomes were assessed by Numerical Rating Scale (NRS), Japanese Orthopaedic Association (JOA) scoring system, and Oswestry Disability Index (ODI) before revision surgery and at 1 week, 3 months, 12 months, and 24 months postoperative. These were also examined every time they came back to the hospital for a review. Results All patients were discharged and no serious comorbidities occurred. Three cases with wound infections and one case with dural laceration were cured and discharged. The end point of follow‐up was August 2018 and the mean follow‐up after revision surgery was 85 months. There were significant differences in NRS. It decreased from 7.32 ± 1.17 to 2.77 ± 1.31 (P < 0.05). The mean postoperative NRS score was 2.27 ± 1.48 (P < 0.05), 1.90 ± 1.51 (P < 0.05), and 2.36 ± 1.36 (P < 0.05) at 3, 12, and 24 months after surgery. There were no statistically significant differences (P > 0.05) in ODI scores. The average JOA score improved from 5.00 ± 1.08 to 8.18 ± 1.59 (P < 0.05) 1 week after revision surgery. RR was between 50% and 70%. Overall satisfaction rates were beyond 80%. Only one patient required subsequent lumber surgery during the follow‐up period. Conclusion If surgical indications are mastered, undergoing PLIF after rLDH may induce efficient pain relief and major improvements in clinical outcome scores, as well as quality of life scores.

Postoperative direct health care costs of lumbar discectomy are reduced with the use of a novel annular closure device in high-risk patients. Spine J 2019; 19:1170-1179. [PMID: 30776485 DOI: 10.1016/j.spinee.2019.02.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2018] [Revised: 02/13/2019] [Accepted: 02/13/2019] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Lumbar discectomy is largely successful surgical procedure; however, reherniation rates in patients with large annular defects are as high as 27%. The expense associated with a revision surgery places significant burden on the healthcare system. PURPOSE To compare the direct health care costs through 5 years follow-up of conventional discectomy (Control) with those of discectomy supplemented by an adjunctive annular closure device (ACD) in high-risk patients with large annular defects. STUDY DESIGN This was a cost-effectiveness study. METHODS All-cause index level reoperations were reviewed from a multicenter, randomized controlled superiority trial that allocated 554 high-risk discectomy patients with large annular defects to either control or ACD. Medicare and private insurer (Humana) direct costs were derived from a commercially available payer database to estimate costs in the US healthcare system, including those associated with facility, surgeon, imaging, follow-up visits, physical therapy, and injections. A 50:50 split between Medicare and commercial insurers was assumed for the base case analysis. The analysis was also performed on a 80:20 commercial:Medicare payer basis. For the base case scenario, a 2-year time horizon and outpatient cost setting was established for the index procedure. Repeat discectomy was assumed to be performed on a 60:40 outpatient-to-inpatient basis. Complications requiring surgery, revisions, and/or fusion were assumed to be managed in the inpatient setting. Total costs of reoperation and per-patient costs of reoperation were compared between groups for both forms of insurers. One author received consulting fees of <$50,000 for the completion of this study, and the other eight authors did not have any financial associations with the current work. Funding for this study was provided by Intrinsic Therapeutics, but all analyses, interpretation, and writing were performed independently by the authors. RESULTS At two years follow-up, use of the ACD reduced the rate of symptomatic reherniations in a large defect population to 13% compared with 25% in the control group (p<.001). This reduction in symptomatic reherniations in the ACD group translated to a savings of $2,802 per patient in direct health care costs compared with Control at 2 years and $5,315 per patient by 5 years based on 50% private and 50% public (Medicare) payer split. Under the scenario of 80:20 private:public insurance reimbursement, the estimated direct cost savings were $3,215 and $6,099 per patient at 2- and 5-years postoperatively, respectively, with the use of the ACD. CONCLUSIONS Symptomatic reherniation and reoperation rates were nearly double among control patients compared with ACD-treated patients, which translated to markedly greater per-patient healthcare costs in the control group, where the ACD was not used.

Abstract
Objectives: To classify patients suffering from low back pain (LBP) into two different groups – patients with lumbar disc herniation (LDH) and patients without this disease based on simple questions and without magnetic resonance imaging (MRI) procedure – and to diagnose the most effective risk factors of LDH. Methods: Four hundred patients aged over 18 years suffering from LBP for over 6 months were randomized into two groups in this cross-sectional study. The data were gathered at Besat clinic, in Kerman, southeast of Iran. Twelve dichotomous questions from the main LDH risk factors were asked. Three statistical classification methods – K-nearest neighbors (KNN), support vector machine (SVM), and logistic regression (LR) – were performed. LR was used in order to diagnose the most important risk factors of LDH. Results: SVM method was more efficient among the small sample sizes, while KNN method showed the best classification relative to other methods when the sample size increased. LR model had the least efficiency of all. The drug use increased the chance of LDH more than 7 times (OR=7.249), and the chance of having LDH among people who had associated illness was 4.847 times more compared with people who did not have. Using hookah increased the chance of having LDH more than twice (OR=2.401), and the chance of smokers for LDH was near four times higher than nonsmokers (OR=3.877). Conclusion: The statistical classification methods had acceptable precisions for diagnosis of LDH patients. It is suggested that neurologists become more familiar with these methods and use them before MRI prescription to decrease the unnecessary burden on health services. Addiction to drugs, cigarettes, and hookah is the main factor in the creation of a lumbar disc herniation.

Abstract
OBJECTIVE Lumbar disc herniation (LDH) is a common spinal problem, with reoperation rates of 6%-24%. Although different surgical techniques are used for treatment, there is still debate regarding whether fusion techniques can reduce the reoperation rate in patients with LDH. METHODS This retrospective study used a 5-year nationwide database to analyze reoperation rates in Taiwan. Patient age groups (≥20 and <90 years) treated by index surgery and reoperation for LDH were identified. Four surgical procedures were included in the analysis: discectomy (DC), anterior lumbar fusion with DC (FA + DC), posterior lumbar fusion (FP), and posterior lumbar fusion with DC (FP + DC). RESULTS There were 1743 index surgeries between 2008 and 2012, with 184 (10.56%) reoperations. Index surgery DC had the highest reoperation rate (n = 121, 20%). The reoperation risk was significantly lower for patients undergoing fusion procedures (FA + DC vs. DC [hazard ratio (HR), 0.24; 95% confidence interval (CI), 0.12-0.47; P < 0.01], FP versus DC [HR, 0.17; 95% C, 0.09-0.33; P <0.01], FP + DC versus DC [HR, 0.31; 95% CI, 0.22-0.44; P < 0.01]). Fusion procedures had significantly higher treatment costs compared with DC (FA + DC vs. FP vs. FP + DC vs. DC: 5851.74 ± 4808.94 vs. 5116.88 ± 3428.97 vs. 4782.16 ± 2902.19 vs. 3846.79 ± 3584.45 U.S. dollars/patient, respectively; P < 0.0001). CONCLUSIONS Among surgical procedures for LDH, fusion techniques are related to lower reoperation rates compared with discectomy, but at the expense of higher medical costs.

Incidence of early postoperative complications requiring surgical revision for recurrent lumbar disc herniation after spinal surgery: a retrospective observational study of 9,310 patients from the German Spine Register. Patient Saf Surg 2018; 12:9. [PMID: 29942349 PMCID: PMC5961485 DOI: 10.1186/s13037-018-0157-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2017] [Accepted: 03/26/2018] [Indexed: 11/10/2022] Open
Abstract
Background The recurrence rate in lumbar disc herniations (LDH) has been reported between 5 and 25%. There are only few data about this phenomenon that occurs within days of the initial operation. We analyse early recurrent LDH by analysis of data from the German Spine register. Methods Data from patients undergoing disc herniation surgery in the lumbar region were extracted from the German Spine Registry between 1st January 2012 and 31st December 2016. Patients with early recurrent LDH within days of initial surgery were separately analysed. Results A total of 9310 surgeries for LDH were documented in the German Spine Register. From these patients 115 (1.2%) presented an early recurrent disc surgeries within days of the initial surgery. The mean age was 70 ± 2.50 years. Most affected segment was L4/5 (47 cases, 41%), followed by L3/4 (45 cases, 39%). The most of our patients showed a normal or overweight Body Mass Index. Surgery for early recurrent LDH was associated with a high rate of incidental durotomies (20 cases, 17.6%). In 3 cases (2.6%) therapy with a lumbar drain was necessary. Conclusions The rate of early recurrent LDH within days of surgery is 1.2%. Age seems to be an important factor in early recurrent LDH while obesity does not. The data of the German Spine Register seems to have a reliable data collection system that can perform multicentre data analysis. The databases from this Register could be used in the future for various purposes, such as the evaluation of multicentre surgical techniques, results in patients with various surgical procedures and basic research in spine surgery.
