Abstract
1. A series of eighty-one hips with slipped upper femoral epiphysis in sixty-three patients is reviewed.
2. The importance of early diagnosis is emphasised.
3. Conservative treatment is condemned.
4. In attempting reduction violent manipulation and strong traction must be avoided.
5. In cases of slight displacement pinning in the position of displacement gives the best results.
6. Three or four small pins are recommended for fixation.
7. When the amount of slip is 50 per cent or more of the diameter of the head gentle manipulation should be tried and, if successful, followed by fixation with three or four pins.
8. The hip with an irreducible slip of 50 per cent or more should be treated by pertrochanteric or subtrochanteric osteotomy.
