The authors examined 125 hips in 74 cases of congenital dislocation, which elapsed 5 to 22 years (average 12.3 years) after reduction.
The results obtained were as follows:
1) Of the cases examined, a majority e, i, 85.6% showed good functional results: in younger age groups under 3 years old at the time of reduction were morc favourable.
2) Excellent cases in function were not always normal in roentgenographic findings.
In the cases with normal function, 32.23% showed poor roentgenographic findings, and the authors suggested that they had to be followed in future.
3) In the cases with epiphysitis and unconcentric position of femoral head at the end of treatment, the results were very poor.
