Purpose . To assess the frequency, risk factors, and management of accidental durotomy in minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Methods This single‐center study retrospectively investigates 372 patients who underwent MIS TLIF were mobilized within 24 hours after surgery. The frequency durotomies, intraoperative closure technique, body mass index, history previous surgery was recorded. Results We identified 32 durotomies 514 levels (6.2%). Analysis showed a statistically significant relation to overweight (body index ≥25 kg/m 2 ; P = 0.0493). Patient age older than 65 years tended be positive predictor for ( 0.0657). Mobilizing on first postoperative day, we observed no durotomy‐associated complications. Conclusions is low, with being factor durotomies. approach seems minimize complications (CSF leakage, pseudomeningocele) because limited dead space soft tissue. Patients can usually without increased risk. technique might thus beneficial prevention immobilization‐associated such as venous thromboembolism. trial registered DRKS00006135
