[Triple osteotomies of the pelvis in children].

The innominate osteotomy described by Salter was used to redirect the acetabulum in the course of the treatment of a number of hip diseases in children. This resulted in an immediate improvement of coverage of the femoral head. One can also expect a more congruent growth of the two constituents of the hip joint in the forthcoming years. In older children in whom rigidity of the pubic symphysis did not permit a sufficient amount of acetabular tilt the acetabulum had to be isolated from the rest of the pelvis by a triple osteotomy which consisted of, in addition to the osteotomy of the ilium, osteotomies of the superior pubic ramus and the ischium or the inferior pubic ramus.
