Abstract:
Delayed onset of sciatic neuropathy after total hip arthroplasty is uncommon, and late hardware-induced sciatic nerve complications are rarely reported. Here, we report a patient in whom the posterior flange of the reinforcement ring caused severe late sciatic nerve injury. Sciatic nerve radiography was useful for diagnosing flange-related sciatic nerve injury.
