Abstract

ABSTRACTAseptic (avascular) necrosis of the femoral head associated with psoriasis is reported. The clinical histories of nine patients with avascular necrosis of the femoral head and one patient with bilateral humeral head osteonecrosis are summarized. Psoriasis was the only associated condition found in three of the patients. Only two patients had received systemic corticosteroids in significant amounts (greater than 1 gm of prednisone). Four patients had received methotrexate therapy for psoriasis. Other possible contributing factors including serum uric acid levels are discussed. Psoriasis should be added to the list of systemic diseases associated with aseptic (avascular) necrosis. Avascular necrosis of the femoral head should be considered in any patient with psoriasis and pain in the hip or thigh.
