Hemarthroses and Warfarin: Joint Destruction with Anticoagulation

Abstract

A 56 year old man was seen because of recurrent right shoulder hemarthroses and a superior vena caval syndrome. Intermittent symptoms had occurred for six years and resulted in marked destructive changes in the right shoulder. Arthroscopy added pathological evidence of this unusual mechanism of arthropathy. Patients on anticoagulants deserve close attention to symptoms of occult bleeding.
