Abstract
Background: Incidental durotomy is a common complication of spine surgery, with reported rates ranging from 2.7% to 17.2%. Although modernsurgical techniques have reduced its occurrence, dural tears remain clinically significant due to their impact on cerebrospinal fluid (CSF) dynamics, perioperative morbidity and surgical outcome. Understanding risk factors, early intraoperative recognition, and current management strategies is essential for optimizing patient outcomes.
Discussion: Dural tears arise from a combination of surgeon-, patient-, and procedure-related risk factors, particularly in revision surgery, severe stenosis, and deformity correction. Disruption of CSF flow may lead to intracranial hypotension, pseudomeningocoele, CSF fistula, meningitis, and radicular symptoms. Intraoperative detection relies on visualization of CSF leakage, Valsalva manoeuvres, and selective use of ultrasonography. Management options include primary suture repair, autologous muscle or fascia grafts, collagen matrices, fibrin sealants, and hydrogel-based products which provide high rates of watertight closure and are especially useful for tears in challenging anatomical locations. Post-operative care utilizing head-low positioning, targeted drain management, CSF-reducing medications, and vigilant monitoring—is crucial to prevent persistent leaks and promote healing.
Conclusion: Although incidental durotomy may increase short-term complications, effective intraoperative repair and structured post-operative protocols generally result in outcomes comparable to uncomplicated cases. Meticulous technique, careful pre-operative planning, and prompt recognition remain central to minimizing the impact of dural tears in spine surgery.
