This 1999 narrative review by DeHart and Riley synthesizes the literature on nerve injuries complicating THA — covering incidence, anatomical vulnerability, risk factors (including hip dysplasia, revision surgery, and leg lengthening), injury classification, prognosis, and the evolving role of intraoperative electrodiagnostic monitoring.
When planning THA in a dysplastic or previously operated hip, flag nerve injury risk explicitly: quantify planned leg lengthening preoperatively (>4 cm is a hard threshold), counsel patients about the peroneal nerve's particular vulnerability, and know that any preserved motor function on day-of-surgery exam is your best prognostic sign.
Causalgia and complete motor-sensory loss are the findings that predict lasting disability.
