1. The "frame" or traction method of reduction of congenital dislocation of the hip is, from the evidence collected in this hospital, both more effective and safer than the manipulative method of reduction. The traction method caused less frequent and less severe lesions of the femoral head than the manipulative method.

2. In cases in which closed reduction failed, open reduction was attempted; the quality of the results depended mainly on the time of operation, the best being in patients operated upon a few weeks after the initiation of the frame treatment.

3. Even with its improved results, still about 40 per cent of cases treated by the frame method showed insufficient reduction or structural changes of the femoral head.

4. Arthrography may help in indicating those cases in which open reduction is desirable.
