Delayed Sciatic Nerve Injury by Posterior Flange of Reinforcement Ring After Acetabular Revision Surgery
Journal of Arthroplasty, 08/16/2012
Nozawa M et al. – Delayed onset of sciatic neuropathy after total hip arthroplasty is uncommon, and late hardware–induced sciatic nerve complications are rarely reported. Here, the authors 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.
