Common etiology was trauma in 48, alcohol in 50, idiopathic in 5, steroids in 52, drug induced in 20, aplastic anemia in 18 and pregnancy in 17 cases. The difference was significant (P< 0.05). ARCO stage 1 was seen in 24, 2 in 46, 3 in 60 and 4 in 80 cases. The difference was significant (P< 0.05). Conclusion: Most common cause of femoral head osteonecrosis was steroid intake, alcoholism and trauma. Key words: Alcoholism, femoral head, Osteonecrosis.
