No definite conclusions can be drawn from a review of this number of cases, but the following impressions were received:
1. No correlation was found between age, motion, pain, and sex.
2. The results for the total group were not outstanding. When, however, individual cases were considered in regard to indications and postoperative course, the results were quite satisfactory.
3. Seventy per cent. of the patients were relieved of pain.
4. There is a definite period after operation during which the range of motion increases and the amount of fixed flexion deformity decreases. This occurs, in general, between the second and third years.
5. No patient in this series either had arthrodesis or wished to have it performed because of a poor arthroplasty result.
6. The best results occurred in patients having slipped femoral epiphysis. The poorest results were in patients with previous infection of the hip.
7. A series of cases of hip arthrodesis is being studied in exactly the same manner. From these two studies, definite conclusions as to indications and contra-indications will be drawn.
