title: Pseudoaneurysm of femoral artery after revision total hip arthroplasty with a constrained cup.
abstract: Delayed vascular injury after revision total hip arthroplasty is a rare and unusual complication. We report a case of a mechanical complication in which migration of a constraining ring locking mechanism used during a revision total hip arthroplasty caused a pseudoaneurysm of the common femoral artery.
