Neurological injuries are rare but significant complications of revision total hip arthroplasty (THA) that can lead to substantial patient disability. This chapter explores the causes and mechanisms of nerve injury following revision THA, including ischemia, compression, traction, and laceration, and provides an overview of their classifications and diagnostic methods. Key topics include the anatomy and regeneration processes of peripheral nerves, the use of diagnostic tools to complement clinical evaluation, including electrodiagnostic studies and MR neurography, and the identification of patient and procedural risk factors like developmental hip dysplasia, prior spinal surgeries, limb lengthening, and surgical approach. Treatment strategies range from supportive care and physical therapy to surgical interventions like nerve decompression and hematoma evacuation. Early diagnosis, effective management, and preventative strategies, including meticulous surgical technique and intraoperative monitoring, are crucial in mitigating risks and improving functional recovery. Comprehensive patient education and counseling are integral to setting realistic postoperative expectations.
