BackgroundAn incidental durotomy (IDT) is a frequent complication of spinal surgery. The conventional management involving a period of flat bed rest is highly debatable. Indeed, there are scanty data and no consensus regarding the need or ideal duration of post-operative bed rest following IDT.ObjectiveTo systematically evaluate the literature regarding the outcomes of mobilization within 24 h and after 24 h following IDT in open lumbar or thoracic surgery with respect to the length of hospital stay, minor and major complications.MethodsA systematic review of the literature using PubMed, Embase and Cochrane and dating up until September 2022 was undertaken following Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Quality of evidence was assessed using a modified version of Sackett's Criteria of Evidence Support.ResultsOut of 532 articles, 6 studies met the inclusion criteria (1 Level-I, 4 level-III and 1 Level-IV evidence) and were analyzed. Overall, 398 patients of mean age 59.9 years were mobilized within 24 h. The average length of stay (LOS) for this group was 5.7 days. Thirty-four patients (8.5%) required reoperation while the rate of minor complications was 25.4%. Additionally, 265 patients of mean age 63 years with IDT were mobilized after 24 h. The average LOS was 7.8 days. Twenty patients (7.54%) required reoperation while the rate of minor complications was 55%. Meta-analysis comparing early to late mobilization, showed a significant reduction in the risk of minor complications and shorter overall LOS due to early mobilization, but no significant difference in major complications and reoperation rates.ConclusionsAlthough early mobilization after repaired incidental dural tears in open lumbar and thoracic spinal surgery has a similar major complication/ reoperation rates compared to late mobilization, it significantly decreases the risk of minor complications and length of hospitalization.© 2023.
