World Neurosurg 2024; 188:e18-e24. [PMID: 38631663 DOI: 10.1016/j.wneu.2024.04.052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 04/09/2024] [Accepted: 04/10/2024] [Indexed: 04/19/2024]
Abstract
OBJECTIVE Dural tears (DTs) are a frequent complication after lumbar spine surgery. We sought to determine the incidence of DTs and the related impact on health care expenditures after lumbar discectomies. METHODS In this retrospective cohort study, all patients with first-time single-level lumbar discectomies at our institution who underwent minimally invasive surgery from 2015 to 2019 were reviewed. Age, sex, weight, height, body mass index, costs, revenues, length of stay, American Society of Anesthesiologists score, Charlson Comorbidity Index, and operative time (OT) were assessed. Exclusion criteria were age <18 years, previous spine surgery, multiple or traumatic disc herniations, and malignant and infectious diseases. RESULTS The follow-up time was at least 12 months postoperatively. Of 358 patients identified with lumbar discectomies, 230 met the inclusion criteria. Incidence of DTs was 3.5%. Mean costs (P < 0.001), economic loss (P < 0.01), and OT (P < 0.0001) were found to be significantly higher in the DT group compared with the control group of patients without a DT. The revenues were not statistically different between the 2 groups (P > 0.05). Further analysis of the control group by profit and loss revealed significantly higher body mass index (P < 0.05), length of stay (P < 0.0001), and OT (P < 0.0001) in the loss group. CONCLUSIONS DTs represent a significant socioeconomic burden in lumbar spine surgery and cause severe secondary complications. The impact of DTs on health care expenses is primarily based on significantly higher OT and a higher mean length of stay.

Abstract
BACKGROUND There is only limited data on the management of cerebrospinal fluid (CSF) fistulas after cervical endoscopic spine surgery. We investigated the current literature for treatment options and present a case of a patient who was treated with CT-guided epidural fibrin patch. METHODS We present the case of a 47-year-old female patient with a suspected CSF fistula after endoscopic decompression for C7 foraminal stenosis. She was readmitted 8 days after surgery with dysesthesia in both upper extremities, orthostatic headache and neck pain, which worsened during mobilization. A CSF leak was suspected on spinal magnetic resonance imaging. A computer tomography (CT)-guided epidural blood patch was performed with short-term relief. A second CT-guided epidural fibrin patch was executed and the patient improved thereafter and was discharged at home without sensorimotor deficits or sequelae. We investigated the current literature for complications after endoscopic spine surgery and for treatment of postoperative CSF fistulas. RESULTS Although endoscopic and open revision surgery with dura repair were described in previous studies, dural tears in endoscopic surgery are frequently treated conservatively. In our case, the patient was severely impaired by a persistent CSF fistula. We opted for a less invasive treatment and performed a CT-guided fibrin patch which resulted in a complete resolution of patient's symptoms. DISCUSSION AND CONCLUSION CSF fistulas after cervical endoscopic spine procedures are rare complications. Conservative treatment or revision surgery are the standard of care. CT-guided epidural fibrin patch was an efficient and less invasive option in our case.

Early ambulation versus prolonged bed rest for incidental durotomies in spine procedures: a systematic review and meta-analysis. Neurosurg Rev 2023; 46:310. [PMID: 37989906 DOI: 10.1007/s10143-023-02201-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 10/09/2023] [Accepted: 10/25/2023] [Indexed: 11/23/2023]
Abstract
Incidental durotomies are frequent complications of spine surgery associated with cerebrospinal fluid (CSF) leak-related symptoms. Management typically involves prolonged bed rest to reduce CSF pressure at the durotomy site. However, early ambulation may be a safer, effective alternative. PubMed, Web of Science, Embase, Cochrane, and Scopus were systematically searched for studies comparing early ambulation (bed rest ≤ 24 h) with prolonged bed rest (> 24 h) for patients with incidental durotomies in spine surgeries. The outcomes of interest were CSF leak, hypotensive headache, additional surgical repair, pseudomeningocele, and pulmonary complications. Systematic reviews and meta-analysis were performed following the Cochrane Handbook for Systematic Reviews of Interventions. We included a total of 704 patients from 6 studies. There was a significant reduction in the incidence of pulmonary complications (RR 0.23; 95% CI 0.08-0.67; p = 0.007) in the early mobilization group. The incidence of CSF leak (RR 1.34; 95% CI 0.83-2.14; p = 0.23), hypotensive headache (RR 0.72; 95% CI 0.27-1.90; p = 0.50), additional repair surgery (RR 1.29; 95% CI 0.76-2.2; p = 0.35), and pseudomeningocele (RR 1.29; 95% CI 0.20-8.48; p = 0.79) did not differ significantly. In patients with incidental durotomy following spinal surgery, early mobilization was associated with a lower incidence of pulmonary complications as compared with prolonged bed rest. There was no significant difference between groups in terms of CSF leak, need for additional repair, pseudomeningocele, and hypotensive headache.

Abstract
Introduction Incidental durotomy (ID) is an intraoperative event associated to prolonged bed rest and hospital stay, antibiotic use, higher patient dissatisfaction, and leg pain among other complications of its postoperative course. Several repair techniques and postsurgical care have been proposed for its management. This study was designed to develop an agreed protocol in cases of ID among Orthopaedic Surgeons (OS) and Neurosurgeons (NS) integrated into a Spinal Surgery Unit. Research question Incidental durotomies management protocol. Materials and methods From 997 eligible cases operated in Hospital del Mar (Barcelona, Spain) from April 2018 to March 2022, demographic, clinical, surgical and postoperative data was collected for statistical analysis from the morbidity and mortality database, with 79 identified IDs. Redo procedures were significantly associated to OS, and cervical and anterior/lateral approaches to NS, both groups were not comparable. Results ID occurred in 7.9% of cases, more frequently after the lockdown (p=0.03), in females (p=0.04), during posterior approaches (p=0.003), and less frequently in the cervical spine (p=0.009). IDs were linked to postoperative infections (p< 0.001) and nerve root damage (p< 0.001). Patients without ID evolved more satisfactorily during the postoperative period (p=0.002), and those with CSF leak (20/79) spent on bed rest more than twice the time as those without (p<0.001). Multivariable logistic regression showed strong association between posterior approaches and ID, between complicated postoperative courses and ID. Discussion and conclusions ID is linked to an adverse postoperative recovery, and it should be primarily repaired under microscope, with early mobilization of patients after surgery.

Abstract
Background Cerebrospinal fluid leakage (CSFL) following spinal durotomy can lead to severe sequelae. However, while several studies have investigated accidental spinal durotomies, the risk factors and influence of clinical management in planned durotomies remain unclear. Methods We performed a retrospective analysis of all patients who underwent planned intradural spinal surgery at our institution between 2010 and 2020. Depending on the occurrence of a CSFL, patients were dichotomized and compared with respect to patient and case-related variables as well as dural closure technique, epidural drainage placement, and timing of mobilization. Results A total of 351 patients were included. CSFL occurred in 4.8% of all cases. Surgical indication, tumor histology, location within the spine, previous intradural surgery, and medical comorbidities were not associated with an increased risk of CSFL development (all p > 0.1). Age [odds ratio (OR), 0.335; 95% confidence interval (CI), 0.105–1.066] and gender (OR, 0.350; 95% CI, 0.110–1.115) were not independently associated with CSFL development. There was no significant association between CSFL development and the dural closure technique (p = 0.251), timing of mobilization (p = 0.332), or placement of an epidural drainage (p = 0.321). Conclusion CSFL following planned durotomy pose a relevant and quantifiable complication risk of surgery that should be factored in during preoperative patient counseling. Our data could not demonstrate superiority of any particular dural closure technique but support the safety of both early mobilization within 24 h postoperatively and epidural drainage with reduced or no force of suction.

Abstract
OBJECTIVE The aim of this study was to assess whether flat bed rest for > 24 hours after an incidental durotomy improves patient outcome or is a risk factor for medical and wound complications and longer hospital stay. METHODS Medical records of consecutive patients undergoing thoracic and lumbar decompression procedures from 2010 to 2020 were reviewed. Operative notes and progress notes were reviewed and searched to identify patients in whom incidental durotomies occurred. The need for revision surgery related to CSF leak or wound infection was recorded. The duration of bed rest, length of hospital stay, and complications (pulmonary, gastrointestinal, urinary, and wound) were recorded. The rates of complications were compared with regard to the duration of bed rest (≤ 24 hours vs > 24 hours). RESULTS A total of 420 incidental durotomies were identified, indicating a rate of 6.7% in the patient population. Of the 420 patients, 361 underwent primary repair of the dura; 254 patients were prescribed bed rest ≤ 24 hours, and 107 patients were prescribed bed rest > 24 hours. There was no statistically significant difference in the need for revision surgery (7.87% vs 8.41%, p = 0.86) between the two groups, but wound complications were increased in the prolonged bed rest group (8.66% vs 15.89%, p = 0.043). The average length of stay for patients with bed rest ≤ 24 hours was 4.47 ± 3.64 days versus 7.24 ± 4.23 days for patients with bed rest > 24 hours (p < 0.0001). There was a statistically significant increase in the frequency of ileus, urinary retention, urinary tract infections, pulmonary issues, and altered mental status in the group with prolonged bed rest after an incidental durotomy. The relative risk of complications in the group with bed rest ≤ 24 hours was 50% less than the group with > 24 hours of bed rest (RR 0.5, 95% CI 0.39-0.62; p < 0.0001). CONCLUSIONS In this retrospective study, the rate of revision surgery was not higher in patients with durotomy who underwent immediate mobilization, and medical complications were significantly decreased. Flat bed rest > 24 hours following incidental durotomy was associated with increased length of stay and increased rate of medical complications. After primary repair of an incidental durotomy, flat bed rest may not be necessary and appears to be associated with higher costs and complications.

Abstract
BACKGROUND In this study, we systematically analyze the effectiveness of the uniportal full-endoscopic (UPFE) and minimally invasive (MIS) decompression for treatment of lumbar spinal stenosis patients. METHODS We performed a systematic search in Medline, Embase, Europe PMC, PubMed, Web of Science, Cochrane databases, Chinese Biomedical Literature Database, China national knowledge infrastructure, and Wanfang Data databases for all relevant studies. All statistical analyses were performed using Review Manager version 5.3. RESULTS A total of 9 articles with 522 patients in the UPFE group and 367 patients in the MIS group were included. The results of the meta-analysis showed that the UPFE group had significantly better results in hospital stay time (mean difference [MD]: -2.05; 95% confidence interval [CI]: -2.87 to -1.23), intraoperative blood loss (MD: -36.56; 95% CI: -54.57 to -18.56), and wound-related complications (MD: -36.56; 95%CI: -54.57 to -18.56) compared with the MIS group, whereas the postoperative clinical scores (MD: -0.66; 95%CI: -1.79 to 0.47; MD: -0.75; 95%CI: -1.86 to 0.36; and MD: -4.58; 95%CI: -16.80 to 7.63), satisfaction rate (odds ratio [OR] = 1.24; 95%CI: 0.70-2.20), operation time (MD: 30.31; 95%CI: -12.55 to 73.18), complication rates for dural injury (OR = 0.60; 95%CI: 0.29-1.26), epidural hematoma (OR = 0.60; 95%CI: 0.29-1.26), and postoperative transient dysesthesia and weakness (OR = 0.73; 95%CI: 0.36-1.51) showed no significant differences between the two groups. CONCLUSIONS The UPFE decompression is associated with shorter hospital stay time and lower intraoperative blood loss and wound-related complications compared with MIS decompression for treatment of lumbar spinal stenosis patients. The postoperative clinical scores, satisfaction rate, operation time, complication rates for dural injury, epidural hematoma, and postoperative transient dysesthesia and weakness did not differ significantly between two groups.

Abstract
Abstract
Background
Incidental durotomy (ID) during lumbar spine surgery is a frequent complication of lumbar spine surgical procedures. Many surgical techniques were described in literature for repair of durotomy, however it is a matter of debate if one technique is a gold standard method of repair. Our study described two groups with posterior and postero-lateral ID that occurred during lumbar spine surgery: group A with 34 cases with a mean age of 49.85 years repaired by primary water tight closure using prolene or silk sutures, and group B with 34 cases with a mean age of 47.18 years treated with augmented primary repair (sutures augmented with a graft from lumbar fascia and tissue sealant "Fibrin glue"). Patients were evaluated for risk factors for durotomy, post-operative clinical outcome, and need for revision surgery.
Results
Eleven cases of group A and nine cases of group B had previous spine surgery. The dural tear was < 2 cm in 41.7% of group A and 83.3% of group B. Better outcome was achieved in 32 patients of group A and 30 patients of group B. Among our study cases 2 patients from group A and 4 patients from group B needed revision surgery due to CSF leak which failed to stop with conservative management and percutaneous blood patch.
Conclusions
Dural closure technique after ID does not seem to influence revision surgery rates due to cerebrospinal fluid (CSF) leakage and its complications. Durotomies that were immediately recognized and treated did not lead to any significant consequences.

Abstract
Incidental durotomies, or dural tears, can be very difficult and time consuming to repair properly when they are encountered in confined spaces. A novel dural repair device was developed to address these situations. In this paper, the novel device was assessed against the use of traditional tools and techniques for dural repairs in two independent studies using an intricate clinical simulation model. The aim was to examine the results of the two assessments and link the outcomes to the clinical use of the novel device in the operating room. The novel device outperformed conventional techniques as measured by dural repair time, CSF leak pressure and nerve root avoidance in the simulation. The results were generally replicable clinically, however, numerous additional clinical scenarios were also encountered that the simulation model was unable to capture due to various inherent limitations. The simulation model design, potential contributors to watertightness, clinical experiences, and limitation are discussed.

Abstract
Objective To evaluate the effects of early ambulation on elderly patients’ postoperative physical functional outcomes, complications, 90‐day readmission rate, and the length of postoperative hospital stay. Methods This is a prospective cohort study conducted between June 2019 and December 2019. The study enrolled 86 elderly patients (39 males) with newly diagnosed lumbar degenerative disease undergoing single‐segment decompression and fusion surgerywere enrolled. Of all 86 patients, 39 voluntarily joined the early ambulation group, and 47 joined the regular ambulation group. The early ambulation group included patients ambulated within 4 h postoperatively, whereas the regular ambulation group included patients who were ambulatory at a minimum of 24 h after surgery. Participants’ baseline characteristics, surgical information, ambulation ability, degree of pain, functional scores, postoperative complications, 90‐day readmission rate, and length of postoperative hospital stay were recorded. Results Participants’ baseline demographic characteristics were balanced between the early ambulation group and the regular ambulation group. The operative time and blood loss were similar between groups. The time before the first‐time ambulation was 4 ± 0.5 h in the early ambulation group and 28 ± 4.5 h in the regular ambulation group. Ambulating distance was significantly longer in the early ambulation group compared with the regular ambulation group on the 1st (63 ± 45 vs 23 ± 60 m), the 2nd (224 ± 100 vs 101 ± 130 m), and the 3rd (280 ± 102.5 vs 190 ± 170 m) ambulation days based on generalized estimating equation analyses. Generalized estimating equation analyses also demonstrated that the ambulating time was longer in the early ambulation group compared with the regular ambulation group on the 1st (10 ± 5 vs 10 ± 5 min), the 2nd (19 ± 7 vs 15 ± 5 min), and the 3rd (22 ± 16.5 vs 27 ± 12 min) ambulation days. Patients in the regular ambulation group experienced a higher degree of pain than the early ambulation group patients, with an odds ratio of 1.627 (P = 0.002). Short‐term functional independence was superior in the early ambulation group, with a lower Roland–Morris disability questionnaire score (P = 0.008) and Oswestry disability index (P < 0.001). The incidences of postoperative urinary retention (early ambulation group: 7.7%, regular ambulation group: 25.5%, P = 0.030) and ileus (early ambulation group: 0%, regular ambulation group: 12.8%, P = 0.030) were significantly higher in the regular ambulation group. The prevalence of at least one complication rate was significantly lower in the early ambulation group than in the regular ambulation group (early ambulation group, 23.1%; regular ambulation group, 46.8%, P = 0.022). The duration of indwelling of the drainage catheter was shorter in the early ambulation group (early ambulation group, 68 ± 24 h; regular ambulation group, 78 ± 20 h, P = 0.001), and the length of the postoperative hospital stay was also shorter in the early ambulation group (early ambulation group, 4 ± 0 days; regular ambulation group: 5 ± 2 days, P < 0.001). However, there was no statistical difference in the 90‐day readmission rate between groups. Conclusion Early ambulation improved patients’ postoperative functional status, decreased the incidence of complications, and shortened postoperative hospital stay in elderly patients undergoing lumbar decompression and fusion surgery.

Abstract
STUDY DESIGN Systemic review and meta-analysis. OBJECTIVES Several studies have reported the impact of accidental dural tears (DT) on the outcome of spinal surgery, some with conflicting results. Therefore, the aim of this study was to carry out a systemic review and meta-analysis of the literature to establish the overall clinical outcome of spinal surgery following accidental DT. METHOD A systemic literature search was carried out. Postoperative improvement in Oswestry Disability Index (ODI), Short-Form 36 survey (SF36), leg pain visual analogue scale (VAS), and back pain VAS were compared between patients with and without DT at different time intervals. RESULTS Eleven studies were included in this meta-analysis. There was a slightly better improvement in ODI and leg VAS score (standardized mean difference of -0.06, 95% confidence interval [CI] -0.12 to -0.01, and -0.06, 95% CI -0.09 to -0.02, respectively) in patients without DT at 12 months postsurgery, but this effect was not demonstrated at any other time intervals up to 4 years. There were no differences in the overall SF36 (function) score at any time interval or back pain VAS at 12 months. CONCLUSION Based on this study, accidental DT did not have an overall significant adverse impact on the short-term clinical outcome of spinal surgery. More studies are needed to address the long-term impact and other outcome measures including other immediate complications of DT.

Epidural hemostasis by autologous fat graft in minimally invasive surgery for lumbar spinal stenosis: In vivo experimental study. Neurochirurgie 2020; 67:362-368. [PMID: 33232714 DOI: 10.1016/j.neuchi.2020.10.009] [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: 04/15/2020] [Revised: 06/22/2020] [Accepted: 10/31/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Epidural hemostasis needs to use small, adapted material in minimally invasive surgery, including bilateral decompression via a unilateral approach for lumbar spinal stenosis. Most surgeons avoid external material for hemostasis because of possible neural tissue damage or complications. We compared epidural hemostasis in minimally invasive surgery by fat graft versus gelatin sponge. METHODS The design was a prospective randomized controlled in-vivo human experimental study. The 24 levels operated on for lumbar spinal stenosis were evaluated in two groups: Group A (control group: gelatin sponge) and Group B (experimental group: fat graft). International Normalized Ratio and Prothrombin Time were assessed preoperatively. Number of cotton hemostats and systolic and diastolic blood pressure were assessed intraoperatively. Epidural hemorrhage area, spinal cord size and ratio of epidural hemorrhage area to spinal cord size were evaluated on early postoperative lumbar MRI. RESULTS Mean epidural hemorrhage area in groups A and B was respectively 1.3±0.5 and 1.2±0.6cm2, and mean spinal cord size 1.2±0.6 and 1.8±0.6cm2 on early postoperative axial lumbar MRI. The two groups did not significantly differ in ratio of epidural hemorrhage/spinal cord size or number of intraoperative hemostats (P=0.36, and P=0.71). CONCLUSIONS The autologous fat graft ensured sufficient and safe epidural hemostasis without serious adverse events in minimally invasive spinal surgery, and is preferable as autologous tissue is easily and quickly harvested. The surgeon feels safe with this technique and does not need external hemostatic agents.

Abstract
OBJECTIVE To obtain real-life data on the most common practices used for management of incidental durotomy (ID) in France. METHODS Data were collected from spinal surgeons using a practice-based online questionnaire. The survey comprised 31 questions on the current management of ID in France. The primary outcome was the identification of areas of consensus and uncertainty on ID follow-up. RESULTS A total of 217 surgeons (mainly orthopaedic surgeons and neurosurgeons) completed the questionnaire and were included in the analysis. There was a consensus on ID repair with 94.5% of the surgeons considering that an ID should always be repaired, if repairable, and 97.2% performing a repair if an ID occurred. The most popular techniques were simple suture or locked continuous suture (48.3% vs. 57.8% of surgeons). Nonrepairable IDs were more likely to be treated with surgical sealants than with an endogenous graft (84.9% vs. 75.5%). Almost two thirds of surgeons (71.6%) who adapted their standard postoperative protocol after an ID recommended bed rest in the supine position. Among these, 48.8% recommended 24 hours of bed rest, while 53.5% recommended 48 hours of bed rest. The surgeons considered that the main risk factors for ID were revision surgery (98.6%), patient's age (46.8%), surgeon's exhaustion (46.3%), and patient's weight (21.3%). CONCLUSIONS This nationwide survey reflects the lack of a standardized management protocol for ID. Practices among surgeons remain very heterogeneous. Further consensus studies are required to develop a standard management protocol for ID.

Abstract
BACKGROUND Incidental durotomy (ID) during spinal surgery is a risk factor for the development of cerebrospinal fluid (CSF) fistula. The rates of ID with or without consecutive CSF fistula vary according to the extent of the surgical procedure. Revision surgery has the highest rates of dural tears. However, not every case of ID leads to CSF fistula requiring revision surgery. The objective of this study was to analyze the predictors for the development of CSF fistula after ID. METHODS This retrospective study included 6024 consecutive patients who had been surgically treated for degenerative spinal disease at our clinic over the past 15 years. Patients who had undergone surgical revision for CSF fistula were assigned to the CSF fistula group. A matched 3:1 control group (ID group) was formed of patients with ID but without CSF fistula. Charts, surgical reports, and radiographic data were reviewed and statistically analyzed for demographics, duration of symptoms, co-morbidities, surgical strategy, and pre- and postoperative neurological performance. RESULTS The 15-year incidence of CSF fistula in the overall population was 0.36% (n=22). The following locations were affected: n=18 lumbar (81.8%), n=2 cervical (9.1%), and n=2 thoracic (9.1%). The extent of ID was similar in both groups. The two groups did not significantly differ with regard to the intraoperative management of dural repair with primary suturing (p=0.345), dural patches, sealant, or collagen matrix (p=0.228; p=0.081; p=0.081). In the postoperative period, bed rest in supine position for 48 hours (p=0.037) and laxative therapy (p=0.034) were the most beneficial treatment modalities for preventing CSF fistula. Patients with CSF fistula were hospitalized significantly longer (21 days vs. 10 days in the control group; p<0.001). CONCLUSIONS This large test group showed a low incidence of postoperative CSF fistula after intraoperative ID. Bed rest and laxative treatment were important approaches to preventing CSF fistula.

Abstract
PURPOSE Incidental durotomy (ID) is a complication occurring in 4-17% of decompressive spinal surgeries. Persisting CSF leakage can occur even after ID repair and requires revision surgery. Prolonged flat bed rest (BR) to reduce the incidence of persisting CSF leakage is frequently applied but highly debated. A randomized controlled trial comparing prolonged BR versus early ambulation after ID repair is lacking. The aim of this study was to investigate the incidence of revision surgery as a result of persistent cerebro-spinal fluid (CSF) leakage and medical complications after immediate or late post-operative ambulation following ID during decompressive spinal surgery. METHODS Ninety-four of 1429 consecutive cases undergoing lumbar spine surgery (6.58%) were complicated by an ID. Sixty patients (mean age of 64 ± 13.28 years) were randomized to either early post-operative ambulation (EA, n = 30) or flat BR for 48 h (BR, n = 30). The incidence of CSF leakage resulting in revision surgery, medical complications and duration of hospitalization were compared between groups. RESULTS Two patients in the BR group and two patients in the EA group underwent revision surgery as a result of persisting CSF leakage. Four patients in the BR group experienced medical complications associated with prolonged immobilization. The duration of hospitalization was 7.25 ± 3.0 days in the BR group versus 6.56 ± 2.64 days in the EA group, p = 0.413. CONCLUSION The results of this study indicate no benefit of prolonged BR after an adequately repaired ID in lumbar spine surgery. LEVEL OF EVIDENCE Level 1b (individual randomized controlled trial).

Abstract
Background Incidental durotomy is a well-known complication of spinal surgery that may occur occasionally. Increasingly, minimally invasive techniques are being used for spinal decompressions in an ambulatory surgical center (ASC) setting. The management of this complication in an ASC setting has not been reported. Methods A total of 832 consecutive minimally invasive decompressive spinal surgeries were performed by a single surgeon in an ASC during the course of 1 year. Incidental durotomies with cerebrospinal fluid leakage were repaired and patients were discharged to home. Patients with a watertight suture dural repair did not receive any modifications to the usual discharge activities allowed. All other patients were treated with bed rest overnight and head of bed restrictions. A protocol for close patient follow-up after discharge was followed. The complications were collected prospectively and analyzed retrospectively. Results There were 30 incidental durotomies (3.6%), with all occurring in the lumbar spine. Suture repair was accomplished in 28 patients (93%). Patch repair was performed in 2 patients (7%). All patients were discharged to home from the ASC. There were 2 short-term complications noted after discharge. The patient safety protocols in place identified the complications and allowed timely interventions. Conclusions Incidental durotomy occurring during minimally invasive spinal decompressive surgery is an occasional event. Suture repair of the laceration is feasible in most instances. Lumbar spine patients may be safely discharged to home from the ASC. Patients can be stratified into those with, or without, a watertight suture dural closure. Those with such a closure, who are without symptoms of intracranial hypotension, do not require modification of their activities. A short period of bedrest with head of bed modification successfully treated the remainder. Hospitalization or routine prolonged bed rest is not necessary. Protocols must be put in place to identify and timely manage potentially serious sequelae.

Abstract
Introduction Incidental durotomy (ID) is a well-known complication in spine surgery. Surveys have not identified a consensus for repair method among neurosurgeons. IDs may lead to complications such as cerebrospinal fluid (CSF) fistula, which may predispose patients to infection, additional procedures, increased length of stay and morbidity. This study aims to compare durotomy repair methods with clinical outcomes. Methods The neurosurgery database at a single institution, Arrowhead Regional Medical Center, was screened for all patients who underwent thoracic and lumbar spine surgery from 2007-2017. Retrospective chart review of operative reports identified patients with an ID. Data collection included: length of stay, infection, additional procedures, time lying flat, CSF fistula formation (primary endpoint) with analysis using t-tests. Results A total of 384 patients underwent initial analysis. Of the 384 patients, 25 had an incidental durotomy based on operative reports. Four patients were excluded from this subset: two were repaired with muscle graft (low N), two were excluded for unclear repair method. The remaining 21 were stratified into two groups, those repaired directly with suture with or without adjunct (N=9) and those repaired indirectly with sealant (N=12). No patients developed a CSF fistula. The indirect group had a length of stay of six days, while the direct group had a length of stay of four days, p=0.184. Two of the nine patients in the direct group and two of the twelve patients in the indirect group developed an infection, p=0.586. Conclusion No patients developed CSF fistulas. Secondary endpoints of length of stay and infection rate did not differ. This study was unable to determine if direct versus indirect repair was a more effective repair method for ID. It is possible that if an incidental durotomy is identified and repaired with a water-tight seal, the repair method does not affect the outcome. It is up to the surgeon to individualize repair based on ability and circumstances.

Abstract
STUDY DESIGN This was a cross-sectional study. OBJECTIVE The objective of this study was to determine spine surgeons' preferences for the intraoperative and postoperative management of intraoperative durotomy (IDT) in decompression and spinal fusion surgeries. SUMMARY OF BACKGROUND DATA Management guidelines for IDT remain elusive. Traditionally, management consists of intraoperative suturing and postoperative bed rest. However, preferences of North American spine surgeons may vary, particularly according to type of surgery. MATERIALS AND METHODS Spine surgeons of AO Spine North America (AOSNA) were surveyed online anonymously to determine which techniques they preferred to manage IDT in decompression and fusion. Differences in preferences according to surgery type were compared using the Fisher exact test. A series of linear regressions were conducted to identify demographic predictors of spine surgeons' preferences. RESULTS Of 217 respondents, most were male (95%), orthopedic surgeons (70%), practiced at an academic center (50%), were in practice 0-19 years (71%) and operated on 100-300 patients per year (70%). The majority of surgeons applied sutures (93%-96%) and sealant (82%-84%). Surgeons also used grafts (26%-27%), drains (18%), other techniques (4%-5%), blood patch (2%-3%), or no intraoperative management (1%-2%). Postoperatively, most surgeons recommended bed rest (74%-75%). Antibiotics (22%), immediate mobilization (18%-20%), reoperation (14%-16%), other techniques (6%), or no postoperative management (5%) were also preferred. Management preferences did not vary significantly between decompression and fusion surgeries (all P-values>0.05). Specialty, practice facility, years in practice, and patients per year were identified as independent predictors of IDT management preferences (P<0.05). CONCLUSIONS Although North American spine surgeons preferred to manage IDT with sutures augmented by sealant followed by bed rest after surgery, less common techniques were also preferred during the intraoperative and postoperative periods. Notably, intraoperative and postoperative IDT management preferences did not change in accordance to the type of surgery being conducted. LEVEL OF EVIDENCE Level V.

Abstract
OBJECTIVE The incidental dural tear is a common complication in lumbar spine surgery. It has been reported that the incidence of dural tears is much greater in endoscopic procedures. Primary closure via suturing remains challenging in endoscopic procedures. The objective of this study was to conduct a literature review on the surgical technique for dural closure and repair in endoscopic spine surgery. METHODS A systematic literature search was performed using the database PubMed. In total, 12 studies reported specifically about the surgical treatment for dural tear in percutaneous and tubular assisted endoscopic technique. The dural tear rate, the technique of dural closure, postoperative time of bed rest, postoperative symptoms related to cerebrospinal fluid fistula, and revision surgery were assessed. RESULTS The overall rate of dural tears in endoscopic spinal surgery was 2.7%, with a range from 0% to 8.6%. The incidence of a dural tear was much greater in cases with lumbar stenosis (3.7%) than in lumbar disc herniation (2.1%). The greatest rate was accompanied by resecting synovial cysts. In addition, the risk of dural tear is greater in bilateral decompression procedures via a unilateral approach. There is no consensus about the ideal technique for dural closure in endoscopic procedures. Furthermore, there is a debate whether dural tear requires surgical treatment or not. CONCLUSIONS An autologous muscle or fat graft in combination with fibrin glue or a fibrin-sealed collagen sponge seems to be a good and safe method for the management of dural tear in lumbar endoscopic spine surgery.

Abstract
STUDY DESIGN Questionnaire. OBJECTIVES Iatrogenic dural tear is a complication of spinal surgery with significant morbidity and cost to the health care system. The optimal management is unclear, and therefore we aimed to survey current practices among Canadian practitioners. METHODS A questionnaire was administered to members of the Canadian Neurological Surgical Society designed to explore methods of closure of iatrogenic durotomy. RESULTS Spinal surgeons were surveyed anonymously with a 55% response rate (n = 91). For pinhole-sized tears, there is no agreement in the methods of closure, with a trend toward sealant fixation (36.7%). Medium- and large-sized tears are predominantly closed with sutures and sealant (67% and 80%, respectively). Anterior tears are managed without primary closure (40.2%), or using sealant alone (48%). Posterior tears are treated with a combination of sutures and sealant (73.8%). Nerve root tears are treated with either sealant alone (50%), or sutures and sealant (37.8%). Tisseal is the preferred sealant (79.7%) over alternatives. With the exception of pin-hole sized tears (39.5%) most respondents recommended bed rest for at least 24 hours in the setting of medium (73.2%) and large (89.1%) dural tears. CONCLUSIONS This study elucidates the areas of uncertainty with regard to iatrogenic dural tear management. There is disagreement regarding management of anterior and nerve root tears, pinhole-sized tears in any location of the spine, and whether patients should be admitted to hospital or should be on bed rest following a pinhole-sized dural tear. There is a need for a robust comparative research study of dural repair strategies.

Abstract
BACKGROUND With the advancement of minimally invasive spinal surgery, endoscopic lumbar decompression has been widely used for the treatment of degenerative lumbar spinal diseases. Iatrogenic dural tear is a relatively common complication in endoscopic lumbar spinal surgery. The golden standard of treatment for iatrogenic dural tear is immediate open conversion and direct repair under microscopic visualization. Recently, most of endoscopic spinal surgery is performed under local anesthesia. So, conversion to open surgery is very embarrassing situation because of the need of additional general anesthesia. But, direct endoscopic dural repair is very difficult procedure due to the limitation of manipulation. No report showed direct dural suture under full endoscopic situation. PURPOSE The purpose of this surgical technique is to provide a method of full endoscopic dural suture repair without conversion to open surgery.

Abstract
STUDY DESIGN Case report and review of literature. OBJECTIVE To present an exceedingly rare occurrence of obstructive hydrocephalus secondary to intraventricular hemorrhage after incidental durotomy during lumbar spine surgery. SUMMARY OF BACKGROUND DATA Incidental durotomies are uncommon but well recognized complications associated with spine surgery. Whereas mostly considered benign with no untoward clinical sequele, it can be symptomatic and present with spinal headaches, pseudomeningoceles, wound infection, meningitis and rarely intracerebral hemorrhage. METHODS A 76-year-old woman underwent L3-S1 laminectomies and fusion for lumbar spondylosis and stenosis. Intraoperatively, a small incidental durotomy was encountered and primarily repaired. RESULTS The patient developed altered mental status on postoperative day 2. Computed tomography of the brain revealed obstructive hydrocephalus and intraventricular hemorrhage. The patient was immediately transferred to the neurosurgery intensive care unit and an external ventricular drain was placed emergently with high opening pressure. Her mental status improved immediately after cerebral spinal fluid diversion. The external ventricular drain was successfully removed after 8 days. The patient made a full recovery and was discharged in stable condition. CONCLUSION Obstructive hydrocephalus after intraventricular hemorrhage is an exceptionally rare but potentially life-threatening complication of incidental durotomies. Spine surgeons should be aware of this rare but serious complication. LEVEL OF EVIDENCE 4.

Abstract
STUDY DESIGN Electronic survey. OBJECTIVE The aim of this study was to identify the international nuances in surgical treatment patterns for severals lumbar degenerative conditions, specifically, to identify differences in responses in each country groupand different treatment trends across countries. SUMMARY OF BACKGROUND DATA Significant variations in treatment of lumbar degenerative conditions exist among spine surgeons, related to the lack of established consensus in the literature. METHODS An online survey with preformulated answers was submitted to 52 orthopedic surgeons, 50 neurosurgeons from four different countries (United States, France, Spain, and Germany) regarding five vignette-cases. Cases included: multilevel stenosis, monolevel stenosis, lytic spondylolisthesis, isthmic lysis, and degenerative scoliosis. The variability for each country was calculated according to the Index of Qualitative Variation (IQV = 0: no variability and 1: maximal variability). We used Fleiss kappa (range: from -1, poor agreement, to 1, almost perfect agreement) for assessing the reliability of agreement between the participants concerning specialties, countries, and age groups. RESULTS For the two stenosis cases, US surgeons were more likely to propose decompression (IQV multilevel = 0.47 and monolevel = 0.32) comparing with European countries more heterogeneous (all IQV >0.70) and more frequently proposing fusion. As regards degenerative scoliosis, all attitudes were extremely heterogeneous with IQV >0.8. Fusion for isthmic spondylolisthesis was more consensual (all IQV <0.63), but attitudes were more heterogeneous for isthmic lysis (IQV ranged from 0.48 to 0.76) with anterior approach proposed in France (37%) and United States (19.2%).The overall interrater agreement was equally slight not only for neurosurgeons (Fleiss Kappa = 0.04) and orthopedic surgeons (Kappa = 0.13), but also for countries (Kappa <0.13) and age groups (Kappa <0.1). CONCLUSION In this study, we found substantial agreement for some spinal conditions but a high variability in some others: intranational and international variations were observed, reflecting the lack of literature consensus.

Abstract
STUDY DESIGN Retrospective case-control study. OBJECTIVE To compare the incidence, management, and outcome of incidental durotomy in revision microdiscectomy with open and minimal-access surgery. SUMMARY OF BACKGROUND DATA Incidental durotomy occurs with a variable incidence of 3%-27% in spine surgery. The highest rate occurs in revision microdiscectomy. The intraoperative and postoperative management of dural tears varies in the literature and the definite impact on clinical outcome has to be clarified. METHODS This is a retrospective study of medical records of 135 patients who underwent revision microdiscectomy, divided into 2 subgroups: OPEN (n=82) versus minimal-access surgery (MINI, n=53). Occurrence of intraoperative dural tears, intraoperative and postoperative management of durotomy, and clinical outcomes, according to MacNab criteria, were retrospectively examined. Statistical comparisons for categorical values between groups were accomplished using the 2-tailed Fisher exact test. P-values <0.05 were considered to be statistically significant. RESULTS The incidence of durotomy in group OPEN was 19.5% (n=16/82) and in group MINI 17.0% (n=9/53) (P=0.822). The majority of durotomies (23/25) were repaired with an absorbable fibrin sealant patch alone. Postoperative cerebrospinal fluid fistula occurred only in 1 case of the OPEN group and was treated with lumbar drainage without the need for a reoperation. Patients with durotomy of the MINI group tended to have better outcome compared with those of the OPEN group without being statistically significant. CONCLUSIONS The incidence of durotomy and postoperative cerebrospinal fluid fistula in lumbar revision microdiscectomy does not significantly differ between minimal-access and standard open procedures. The application of a fibrin sealant patch alone is an effective strategy for dural repair in revision lumbar microdiscectomy.

Abstract
STUDY DESIGN A retrospective database review. OBJECTIVE The aim of this study was to identify whether dural tears increase costs and the risk of wound complications and serious adverse events during the postoperative period following primary lumbar discectomy in elderly Medicare beneficiaries. SUMMARY OF BACKGROUND DATA Rates of incidental durotomy during lumbar spine surgery range from 1% to 17%. The full economic and medical burden of this complication remains unclear, particularly as it occurs during lumbar discectomy in elderly patients. METHODS The full set of prospectively gathered Medicare insurance data (2005-2012) was retrospectively reviewed. Patients who underwent primary lumbar discectomy for lumbar disc herniations from 2009 to quarter 3 of 2012 were selected. This cohort (n = 41,655) was then divided into two subgroups: those who were diagnosed with incidental durotomy on the day of surgery (n = 2052) and those who were not (control population). To select a more effective control population, patients of a similar age, gender, smoking status, diabetes mellitus status, chronic pulmonary disease status, and body mass index were chosen at random from the control population to create a control cohort. In-hospital costs, length of stay, and rates of 30-day readmission, 90-day wound complications, and 90-day serious adverse effects were compared. RESULTS An incidental durotomy rate of 4.9% was observed. Higher rates of wound infection [2.4% vs. 1.3%; odds ratio (OR) 1.88; 95% confidence interval (95% CI): 1.31-2.70; P < 0.001], wound dehiscence (0.9% vs. 0.4%; OR 2.39; 95% CI: 1.31-4.37; P = 0.004), and serious adverse events related to incidental durotomy (0.9% vs. 0.2%; OR 4.10; 95% CI: 2.05-8.19; P < 0.0001) were observed in incidental durotomy patients. In-hospital costs were increased by over $4000 in patients with incidental durotomy (P < 0.0001). CONCLUSION Incidental durotomies occur in almost one in every 20 elderly patients treated with primary lumbar discectomy. Given the increased hospital costs and complication rates, this complication must be viewed as anything but benign. LEVEL OF EVIDENCE 4.

Abstract
Study Design Retrospective chart review. Objective Postoperative cerebrospinal fluid (CSF) leak is a known complication of intraoperative durotomy. Intraoperative placement of subfascial epidural drains following primary dural repair has been proposed as a potential management strategy to prevent formation of CSF cutaneous fistula and symptomatic pseudomeningocele. Here we describe our experience with subfascial drain after intentional durotomy. Methods Medical records of patients who underwent placement of subfascial epidural drains during spinal procedures with intentional intraoperative durotomies over a 4-year period at two institutions were retrospectively reviewed. Primary outcomes of interest were postoperative CSF cutaneous fistula or symptomatic pseudomeningocele formation. Results Twenty-five patients were included. Mean length of follow-up was 9.5 months. Twelve patients (48%) underwent simultaneous arthrodesis. The average duration of the drain was 5.3 days with average daily output of 126.5 mL. Subgroup analyses revealed that average drain duration for the arthrodesis group was 6.33 days, which is significantly greater than that of the nonfused group, which was 3.7 days (p = 0.016). Similarly, the average daily drain output for the arthrodesis subgroup at 153.1 mL was significantly higher than that of the nonfused subgroup (86.8 mL, p = 0.04). No patient developed postoperative CSF cutaneous fistula or symptomatic pseudomeningocele or had negative sequelae associated with overdrainage of CSF. One patient had a delayed wound infection. Conclusions The intraoperative placement of subfascial epidural drains was not associated with postoperative development of CSF cutaneous fistula, symptomatic pseudomeningocele, overdrainage, or subdural hematoma in the cases reviewed. Subfascial closed wound drain placement is a safe and efficacious management method after intentional spinal durotomies. It is particularly helpful in those who undergo simultaneous arthrodesis, as those patients have statistically higher daily drain output and longer drain durations.

Abstract
Study Design Retrospective case series. Purpose To examine the efficacy of TachoSil for vessel injury in 6 patients who underwent anterior lumbar fusion surgery (ALF). Overview of Literature ALF for the lumbar spine has a high rate of success, although intraoperative concerns and iatrogenic complications are known, and injury of a major vessel is sometimes a complication. The efficacy of TachoSil, a fibrin-based hemostat, has been reported for several types of surgery; however, use of TachoSil for ALF surgery has not been described. Here, we report on the efficacy of TachoSil in 6 patients, who underwent ALF after vascular surgeons having difficulty in repairing vessels. Methods Two man and 4 women with average age of 50.8±10.9 (mean±standard deviation) were diagnosed with a vertebral tumor (2 patients), L4 degenerative spondylolisthesis (2 patients), and L5 spondylolytic spondylolisthesis (2 patients) and underwent ALF. The blood vessels injured included the common iliac vein in 2 patients and a branch of a segmental artery from the aorta in 4 patients. We consulted a vascular surgeon to suture or repair the vessels during surgery, and although the vascular surgeon attempted to address the injuries, suturing or repair was not possible in these cases. For this reason, we used TachoSil to repair the injury in the vessels walls or to stop the bleeding. Results Time to pressure hemostasis using TachoSil was 34±12 minutes, and total blood loss was 1,488±1,711 mL. Nevertheless, all vessel injuries were controlled by the use of TachoSil. Conclusions We recommend the use of TachoSil for vessel injuries that vascular surgeons cannot suture or repair during ALF surgery.

Abstract
OBJECTIVE No evidence-based guideline has been approved for the postoperative management of pediatric patients with tethered cord syndrome (TCS). The purpose of this randomized clinical trial was to evaluate the effectiveness of prone positioning and acetazolamide administration on complication rates following spinal cord untethering surgeries. METHODS From October 2012 to February 2015, patients with a primary diagnosis of TCS who were admitted to the Children's Medical Center Hospital of Iran were randomly allocated to 1 of 4 intervention modality groups postoperatively: 1) Group A, acetazolamide administration for 10 days; 2) Group B, prone positioning for 10 days; 3) Group C, acetazolamide administration and prone positioning for 10 days; and 4) Group D, no intervention. CSF leakage, CSF collection, wound dehiscence, operative site infection, and secondary surgical wound repair were considered failure. RESULTS A total of 161 patients were enrolled in this study (Group A, n = 39 [24.2%]; Group B, n = 41 [25.5%]; Group C, n = 39 [24.2%]; and Group D, n = 42 [26.1%]). The overall failure rate was 12.42% (20 patients). Complication rates through pooled analyses were as follows: CSF leakage (n = 9, 5.6%), CSF collection (n = 12, 7.5%), wound dehiscence (n = 2, 1.2%), and infection of operation site (n = 3, 1.9%). Two patients (1.2%) required surgical secondary wound repair due to complications. CSF leakage and collection rates were significantly lower in patients who underwent prone positioning (p = 0.042 and 0.036, respectively). The administration of acetazolamide, either isolated or in combination with prone positioning, not only could not significantly lower the complication rates, but also added the burden of side effects. CONCLUSIONS The current study demonstrates the possible role of prone positioning in mitigating the complication rates subsequent to untethering surgeries. Clinical trial registration no.: NCT01867268 ( clinicaltrials.gov ).

Abstract
BACKGROUND Acquiring operative skills in the course of a structured neurosurgery residency training program is vital to safely operating on patients autonomously upon board certification. We tested the hypothesis that the complication rates and outcome of microscopic lumbar spinal stenosis (LSS) decompression done by supervised residents are not inferior to those of board-certified faculty neurosurgeons (BCFNs). METHODS Retrospective single-center study performed at a Swiss teaching hospital comparing consecutive patients undergoing surgery for LSS by a supervised neurosurgery resident (teaching cases) to a consecutive series of patients operated on by a BCFN (non-teaching cases). The primary endpoint was occurrence of complications during surgery. Secondary endpoints were patients' clinical outcomes 4 weeks after surgery, categorized into a binary responder and non-responder variable, occurrence of postoperative complications, need for re-do surgery, and clinical outcome until the last follow-up (FU). RESULTS In a total of n = 471 operations, n = 194 (41.2 %) were teaching cases and n = 277 (58.8 %) non-teaching cases. A longer operation time (single-level procedures: mean 100.0 vs. 83.2 min, p < 0.001) was recorded for teaching cases, while estimated blood loss was equal (single-level procedures: mean 109.9 vs. 117.0 ml, p = 0.409). In multivariate analysis, supervised residents were as likely as BCFNs to have an intraoperative complication (OR 0.92, 95 % CI 0.41-2.04, p = 0.835). They were as likely as BCFNs to achieve a favorable 4-week response to surgery (OR 1.82, 95 % CI 0.79-4.15, p = 0.155). Until final FU, the likelihood for patients in the teaching group to suffer from postoperative complications (OR 1.07, 95 % CI 0.46-2.49, p = 0.864) or require re-do surgery (OR 0.68, 95 % CI 0.31-1.52, p = 0.358) was similar to that of the non-teaching group. CONCLUSIONS Complication rates and short- and mid-term outcomes following LSS decompression were comparable for patients operated on by supervised neurosurgery residents and senior neurosurgeons. Our data thus indicate that a structured neurosurgical hands-on training including LSS decompression is safe for patients.

Abstract
OBJECTIVE Incidental durotomy (ID) during lumbar spine surgery is a frequent complication of growing clinical relevance as the number and complexity of spinal procedures increases. Yet, there is still a lack of guidelines for the treatment of ID with a large heterogeneity of established surgical techniques. The aim of this study was to investigate the efficacy of dural suturing in patients having ID during degenerative lumbar spine surgery, compared with other dural closure techniques. METHODS Of 1173 consecutive patients undergoing degenerative lumbar spine surgery from July 2013 to March 2015, in 64 (5.4%) patients 69 (5.8%) IDs occurred. The patients were divided into 3 groups depending on the dural closure technique used: group A, sole dural suture (n = 12, 19%); group B, patch only (TachoSil and/or muscle and/or fat) (n = 22, 32%); group C, dural suture in combination with a patch (n = 34, 49%). The primary end point was revision surgery caused by complications of cerebrospinal fluid leakage after 6 weeks. The secondary end points were operation time and hospitalization time, as well as surgical morbidity. RESULTS The 3 groups showed no significant difference in rates of revision surgery (group A: n = 1, 1.4%; group B: n = 4, 5.8%; group C: n = 3; 4.3%; P = 0.5). Furthermore, no significant difference for hospitalization time, operation time, and clinical outcome was found. Extent of ID, American Society of Anesthesiology score, postoperative immobilization, and insertion of a drainage tube were not associated with higher rates of revision surgery. Applying suction once a drainage tube was placed was found to be a significant risk factor for revision surgery (P = 0.003). Furthermore, patients undergoing revision surgery had a significantly higher body mass index (33 kg/m(2) vs. 26.37 kg/m(2); P = 0.006; odds ratio 1.252; P = 0.004). CONCLUSIONS Based on our results, the dural closure technique after ID does not seem to influence revision surgery rates due to cerebrospinal fluid leakage and its complications. Further prospective randomized studies are needed to confirm our results.

Abstract
Persistent posttraumatic CSF fluid leakage may present a challenge to manage. Failure to address the leakage may result in complications such as meningitis, septicemia, radiculopathy, muscle weakness, and back pains. While the majority of the leakages may be managed conservatively, large dura defects as a result of gunshot wounds or motor vehicle accidents are best managed by surgical interventions. This may range from primary closure of the defect to fascial grafts, adhesive glues, and flaps. We present our experience with the use of flaps in a patient who had sustained such wounds in the thoracic spine. An island latissimus dorsal flap and a perforator fasciocutaneous flap were used to close the defect. Postoperatively the patient recovered well and the wounds healed without any complications.
