[Nonarthroplasty methods for developmental dysplasia of the hip with complete dislocation at the age of 8-25 patients].

It is a tough challenge treatment of complete dislocation from developmental dysplasia of the hip at the age of 8-25 patients. Although the procedure of total hip arthroplasty (THA) can improve joint function significantly, the failure rate still remains high. Hip arthrodesis remains a sensible and safe option. A stable and painless hip joint can be obtained without multiple operations. Ganz et al.had described a modified Colonna capsular arthroplasty and surgical hip dislocation with well joint functions, radiographic findings and the less complications of the femoral head osteonecrosis. There is a obvious advantage in postponing THA, and subsequent THA could be technically easier and safer in a dislocated hip. The procedure of pelvic support osteotomy, which is proposed by Ilizarov, combined two steps of femur osteotomy and femur lengthening, provides an effective treatment option for adolescent hip dysplasia or dislocation. By this procedure, the hip could be reserved, the limb length recovered and the gait improved significantly. Resection arthroplasty is a reliable method, by which 90% dysplasia patients received a painless joint and good functional outcomes. In view of certain drawbacks, it is used only as a salvage operation currently. This article reviews some alternative nonarthroplasty methods for developmental dysplasia of the hip with complete dislocation. Good clinical results can be obtained through strict indications and nice surgical skills.
