In forty-five patients, twenty-three with congenital dislocations and the
rest with paralytic or other disturbances, this new displacement osteotomy of
the hip joint was done when other iliac osteotomies were considered
ineffective. The patients, seven to seventeen years old, were followed two to
ten years. Of the fifty-two procedures, forty were satisfactory. Most of the
unsatisfactory results were in cases of myelodysplasia, peroneal atrophy, and
cerebral palsy.
