Abstract

The congenital dislocation of the hip is one of the most common congenital disease in the field of the orthopedic surgery. For the normal development of the acetabulum and femoral head, the displaced femoral head shouid be replaced in the acetabular socket as early as possible. In most cases treated in proper time, closed reduction is successful. If not, operative correction will almost always be necessary due to abnormal changes of the acetabulum and femoral head. We experienced 33 cases in 32 patients of the congenital dislocation of the hip at the Department of Orthopedic Surgery of Hanyang University Hospital from May, 1972 to December, 1980. The results obtained were as follows: 1. The most common aged group at the first visit was ranged from 12 months to 24 months and the preponderance of girl to boy was 3.6:1. 2. The ratio of left to right side was 1.6:1. 3. In delivery history, there were 3 cases of breech presentation, 1 case of Cesarean section and 1 case of prematurity. The associated congenital anomaly was observed in a case of which combined internal tibial torsion and talipes metatarsus varus deformity. 4. In 33 cases in 32 patients, 22 cases were treated conservatively and 11 cases were treated surgically. The results of treatment were excellent in 21 cases, good in 11 cases and fair in 11 case. We experienced 4 cases of neglected congenital dislocation of the hip in the period of late childhood, 3 cases were treated with Chiari osteotomy and the other 1 case was treated with Colonna capsular arthroplasty. The overall results were excellent.
