Incidental dural tears or durotomy (ID) during lumbar decompressive surgery is a relatively rare complication causing severe consequences. Their incidence varies widely among different authors (1-17%) and in general depends on the type and complexity of the spinal procedures performed. With the present investigation the authors aim to evaluate the incidence of incidental durotomies during the different types of decompressive and reconstructive surgical procedures in the lumbar region, also indicating the most common reasons for incidental durotomies, treatment options and the early and remote outcome. ⋯ IDs should be considered as a serious complication with a multitude of unwanted consequences for the patients. Prevention is the best way to treat the complications and disability that attend the unwanted dural tears. Knowing about the mechanisms and predisposing factors for that objectionable complication is a matter of utmost importance when planning and performing spinal surgical procedures.
