Abstract
We followed up 36 cases, 49 hip joints that were left femoral heads lateralized after conservative treatment in congenital dislocation of the hip joint. And next results were obtained.
1. Frequency of lateralization of the femoral head reduced by Pavlik's method was more that by other method.
Pavlik's method 16.2%
other methods 10.9%
2. Prognosis of the lateralization of the femoral head not combined the change of the epiphyseal center of the head was as follows.
Only 5 cases of these 36 joints were poor results. Acetabular angle of 4 joints of these 5 was over 30 degrees.
11 joints treated by Pavlik's method showed all good results.
3. In 13 joints the lateralization of the femoral head combined the aseptic changes of the epiphyseal center of the head.
10 joints of these 13 showed poor results.
4. The evidence was not obtaind that the grade of dislocation and excessive antetorsion caused lateralization of the head and influenced prognosis.
5. Arthrography was done in 9 cases, these cases showed lateralization of the femoral head.
6 joints of these 9 had some obstacles in the joints.
