Rheumtoid arthritis (RA) is one of the many etiologic agents in bone necrosis of femoral head (FHN). Practically most cases of FHN in RA have received corticosteroid therapy, but a few cases occur independently of corticosteroids. We encountered a rare case of FHN associated with RA. This case was a 54-year-old male with an eight-year history of RA, and he had been treated with an anti-inflammatory drug for three months. The drug contained about 15mg of corticosteroid as total dosage. He had had increasing joint pain, loss of motion and limping gait in left hip for one year. X-rays revealed collapse of his left femoral head. A total dosage of 15mg of corticosteroids is very small to bring about steroid-induced necrosis. So it is thought that our case occured independently of corticosteroids.
