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 surgeons 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.1.Introduction Recurrence after initial discectomy for lumbar disc herniation(LDH)occurs frequently and sometimes may even be considered inevitable.A better understanding of the risk factors for disc recurrence may allow us to develop preventative measures to reduce the incidence of recurrent LDH.The goal of this review is to produce up-to-date,evidence-based recommendations from two international consensus meetings of the World Federation of Neurosurgical Societies(WFNS)Spine Committee on the risk factors for LDH recurrence,surgical and postoperative techniques to avoid recurrence after primary surgery,and the best management of LDH recurrence.Our recommendations are developed for practicing spine surgeons worldwide,with a particular emphasis on those in low and middle-income countries.2.Methods We performed a systematic literature search in PubMed,Medline,*Corresponding author.E-mail address:(M.Zileli).Contents lists available at ScienceDirect World Neurosurgery:X journal homepage: https:/doi.org/10.1016/j.wnsx.2024.100275 Received 28 July 2023;Accepted 1 February 2024 World Neurosurgery:X 22(2024)1002752and Google Scholar databases from 2012 to 2022 using the keywords“lumbar disc recurrence.Pubmed had 1667 initial results,while Med-line had 688 and Google scholar had 16,800 initial results.We applied standardized inclusion/exclusion criteria to narrow our search to 57 final papers.Inclusion criteria included papers in the English language with full text available,prospective,or retrospective clinical trials,meta-analyses,randomized controlled trials,and systematic reviews.Non-human studies and case reports with 50 patients were excluded.Fig.1 shows our search methodology.Papers covered the following topics:(1)Definition and incidence of recurrence after lumbar disc surgery;(2)Prediction of recurrence before primary surgery;(3)Pre-vention 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 collected and organized these papers to answer the following questions.1.What is the definition and incidence of LDH recurrence after lumbar disc surgery?2.Can we predict recurrence before the initial surgery?3.Can recurrence be prevented by surgical measures such as minimally invasive discectomy or open discectomy,aggressive discectomy,and/or ligament repair techniques?4.Can recurrence be prevented by postoperative measures such as ac-tivity restriction,smoking cessation,weight loss,special exercises,and/or muscle strengthening?5.What is the best treatment for recurrent disc herniation:open dis-cectomy,microdiscectomy,endoscopic discectomy,or fusion?6.Are recurrent disc herniation outcomes the same as primary disc surgery?Table 1 contains a summary of the reviewed papers,divided into“Incidence of recurrence”(3 papers),“Prediction of recurrence”(15 papers),“Value of annular closure devices”(3 papers),“Comparison of surgical techniques”(23 papers),“Value of fusion surgery“(8 papers),and“Outcomes of recurrent disc surgery(8 papers).Search results were presented and discussed at two international consensus meetings,the first in Karachi,Pakistan,in May 2022,and the second in Istanbul,Turkey,in September 2022.Ten members of the World Federation of Neurosurgical Societies(WFNS)Spine Committee who are world experts in spine care discussed and voted anonymously on the statements.We used the Delphi method to generate a consensus:participants graded each statement using a Likert-type scale from 1 to 5(1=strongly agree,2=agree,3=somewhat agree,4=disagree,5=strongly disagree).Results are presented as a percentage of respondents who scored each item as 1,2,or 3(agreement)or as 4 or 5(disagreement).Positive or negative consensus was achieved when the sum for agree-ment or disagreement,respectively,was 66%(see Table 2).3.Results and discussion 3.1.Definition and incidence of recurrence after lumbar disc surgery The definition of a recurrent lumbar disc herniation is a new disc herniation at the index level and on the same side as the initial surgery.Although some papers accept contralateral disc herniation at the same level as recurrence,such a definition causes confusion.A retrospective study1 of 5626 Japanese patients undergoing initial disc excision be-tween 1988 and 2007 reported 205 LDH recurrences.Of these,only 101 cases(1.8%)were real LDH recurrences,in that they were at the same level and on the same side as the primary herniation.Studies in literature report varying recurrence rates for LDH,from 0.5%up to 21%.17 Same-side and same-level disk recurrences may vary from 3.8 to 7.4%.1 A systematic review published in 2016 and including 30 studies reports a same-level,same-side LDH recurrene rate Abbreviations WFNS World Federation of Neurosurgical Societies MRI Magnetic resonance imaging CT Computed

develop and validate a nomogram useful in predicting rLDH.352 patients/32 recurrence The course of disease,Pfirrmann grade,Modic change,migration grade are risk factors for recurrence.6 Hao et al15 2020 Retrospective 3 Relationship between Modic changes and rLDH 102 patients Recurrent lumbar disc herniation occurs when Modic changes or herniated cartilage are present.7 Huang et al12 2016 Metaanalysis 2 Risk factors for rLDH 17 studies smoking,disc protrusion,and diabetes are predictors for rLDH.8 Kim et al17 2015 Retrospective 3 Risk factors for recurrence of L5S1 level.39 recurrences at L5-S1 Moderate disk degeneration,a large sROM,a small L5 vertebral transverse process,and a low iliac crest height index are biomechanical risk factors of rLDH in L5S1.Being male and having a large annular defect are also risk factors.9 Shin et al22 2018 Retrospective 3 To investigate risk factors for rLDH after discectomy including lumbosacral transitional vertebrae 119 patients/21(17.6%)recurrence Lumbosacral transitional vertebrae and a hypermobile disc in flexion-extension radiography are risk factors for rLDH.10 Siccoli et al9 2021 Retrospective 2 To investigate risk factors for rLDH especially the effect of age on recurrence in a prospective registry 3013 patients/166(5.5%)reoperation Younger patients do not have a higher reoperation probability.However,older patients tend to experience recurrent LDH significantly earlier after the index surgery.11 Yao et al26 2016 Retrospective 3 To search the risk factors of recurrence after MED 111 patients Age(50 years old),obesity(body mass index 25),the treatment period,modic change,nonmigrated herniation,and central herniation are potential risk factors for recurrence.12 Yin et al14 2018 Meta-Analysis 2 To search the epidemiological prevalence of recurrent herniation in patients following PELD and to analyze the potentially related risk factors.63 studies PELD is associated with 3.6%recurrence rate.It usually occurred within 6 months postoperatively.Older age(50 years),obesity(BMI 25),upper lumbar disc and central disc herniation are risk factors for recurrence after PELD.Different surgical approaches(PETD or PEID),lateral discs,migrated discs and foraminoplasty did not affect the incidence.13 Li et al21 2020 Retrospective 3 To evaluate the association between facet joint parameters(facet orientation and facet tropism)and rLDH 246 patients With the decrease of facet orientation,the risk of rLDH increases continuously.Facet joint parameters may play a more
