title: Warfarin-associated intracapsular hemorrhage causing an acutely painful total hip arthroplasty: a rare complication of prolonged anticoagulant therapy.
abstract: Hemorrhage is the most prevalent adverse effect of oral anticoagulant therapy. The incidence of bleeding complications is related to the duration and range of therapy. A patient on long-term warfarin anticoagulation developed a spontaneous intracapsular bleed into a total hip arthroplasty that had been implanted 11 years before. Joint aspiration allowed early recognition with immediate resolution of symptoms. Diagnosis and treatment of this rare complication are discussed with a review of the literature.
