A premature degenerative osteoarthrosis of the hip joint secondary to a severe dysplastic or subluxated hip can occur early in relatively young patients. In the dysplastic acetabulum the weight-bearing area is diminished and the shallow acetabulum is directed to a vertical position. On purpose not only to restore a more anatomical relationship between the acetabulum and the femoral head, but also to prevent progression of osteoarthrosis of the hip, 22 hips in 20 patients were treated with acetabular osteotomy by Wagner. This paper reports on operative indications and radiological results at a mean follow-up of 9.5 months.
