The treatment of congenital dislocation and subluxation of the hip in the older child.

Two additional risks are involved in the treatment of congenital dislocation of the hip when diagnosis is made too late: avascular necrosis following the reduction, and residual coxo-femoral dysplasia. Our study and the experience that we acquired within the past 10 years on 142 hips show the value of closed reduction by slow progressive traction with abduction and internal rotation, and the value of innominate osteotomy. These are two strong points on which we can base our treatment in order to further improve the results of our efforts in this field.
