[Indication and efficiency of different operations in congenital hip dislocation (author's transl)]

The efficiency of different operations for congenital hip dysplasia is discussed here. Up to the age of 6 years Salters osteotomy and the acetabuloplasty of Lance in a modified form will achieve similar results. In cases with an acetabular index higher than 35 degrees acetabuloplasty is more effective. After our own experience acetabuloplasty can be used in all age groups where there is no congruency between acetabulum and femoral head. In congruent cases Salters osteotomy can be used up to 14 years combined with varus-osteotomy if dysplasia is of moderate degree. Chiaris osteotomy should be reserved for extreme cases, where other methods will not succeed.
