Atraumatic Osteonecrosis of the Distal Radius and Ulna: Case Series and Review

Atraumatic multifocal osteonecrosis is defined as the occurrence of this entity in 3 or more anatomic locations, and is rare. We identified 6 patients with osteonecrotic lesions in the distal ulna, radius, or both. The purposes of this study were to describe the clinical manifestations of atraumatic multifocal osteonecrosis affecting these bones, to identify risk factors for developing the disease in these locations, and to evaluate the success of treatment by percutaneous drilling.
