The age at treatment were under the age of 6 months in 49 hips, 7 to 12 months in 5, 13 to 18 months in 30 and 19 to 24 months in 14. 3. The initial treatment of the 98 hips were Pavlik harness in 49 hips, closed reduction in 18, and open reduction in 31. 4. Pavlik harness was applied to the patients under the age of 7 months and the results were acceptable in 37 hips (76%), uncertain in 4 (8%) and unacceptable in 8 (16%). The 8 unacceptable hips were retreated by closed reduction in 6 hips and open reduction in 2. 5. Closed reduction was applied to the patients ranging from the age of 4 months to 21 months and the results were acceptable in 14 hips(78%), unacceptable in 4 (22%). The 4 unacceptable hips were retreated by open reduction in 3 hips and Salter innominate osteotomy in l. 6. Open reduction was applied to the patients ranging from the age of 7 months to 20 months, and the results were acceptable in 26 hips (84%), uncertain in 3 (10%) and unacceptable in 2 (6%). The one of 2 unacceptable hips was retreated by Salter innominate osteotomy. 7. The overall results of 98 hips following initial treatment were acceptable in 77 hips (79%), uncertain in 7 (7%), and unacceptable in 14 (14%).
