The authors have experienced 8 hips of slipped capital femoral epiphysis out of 6 adolescents which are known to be very rare in this country since September, 1983 at Department of Orthopaedic Surgery, The Korea University Guro Hospital. They were 3 males and 3 females at age range between 10 to 14 years. Laterality of involvement was 3 in left, 1 in right and 2 in bilateral. Staging was acute in 1 case, acute on chronic in 3 cases and chronic in 4 cases. And the degree of slipping was mild in 4 cases, moderate in 4 cases. Among the 6 patients, 2 were associated with primary hyperparathyroidism and 1 with hypothyroidism. Treatments offered were closed reduction and pin fixation for 5 hips and conservative with control of underlying disease for 2 hips. One hip which was chronic was treated with Southwick osteotomy. The prognoses of the cases were generally good except one which showed slowness in regaining of motion after Southwick osteotomy.
