Typically, sciatic neuropraxia occurs from traumatic impaction or compression due to posterior hip fracture-dislocation. We report 2 patients with sciatic nerve entrapment within the posterior column components of their associated both-column acetabular fractures. Following neuroplasty through a Kocher-Langenbeck surgical approach, both patients' neurologic function improved. This unlikely cause of neurologic compromise should be considered in all patients with symptoms of sciatic nerve injury or irritation and particularly in the presence of a mechanical block during posterior column reduction through an ilioinguinal approach. © 2009 Lippincott Williams & Wilkins, Inc.
