Evaluation of intra-pelvic screw position prior to revision total hip arthroplasty--a report of 2 cases.

摘要

Neurovascular injury during total hip revision arthroplasty is rare, but potentially catastrophic. We report two patients requiring revision total hip arthroplasty with intrapelvic screw tips located close to the iliac artery. The screw tips were separated from artery by a retroperitoneal exposure prior to revision surgery. Assessment of screw position by computed tomography (CT) is important prior to revision total hip arthroplasty.
