Cementation for femoral head osteonecrosis: a preliminary clinic study.

Journal Article (Clinical Trial;Journal Article)

Treatment for femoral head osteonecrosis has been less successful in late stages of the disease, after progression to collapse. The current authors treated 21 patients (22 hips) with Stage III osteonecrosis by a technique of open reduction and fixation with methylmethacrylate cement (cementation). The followup ranged from 1 to 3 years (average, 1.7 years). Patient progress was followed using preoperative and postoperative Harris hip scores, Western Ontario and McMaster Universities Osteoarthritis Index, and a health status questionnaire (Short Form-36). Patients were staged preoperatively using the Association Research Circulation Osseous international classification system and radiographic evaluation was done intraoperatively and postoperatively. The Harris hip score, Western Ontario and McMaster Universities Osteoarthritis Index, and Short Form-36 physical health scores improved significantly from 53.5 to 78.0, 66.0 to 48.1, and 27.0 to 40.0, respectively. The outcome was worse for patients with more advanced disease. Six patients, all with severe disease, had total hip arthroplasty. Cementation is technically simple, enables patients' immediate postoperative pain relief and improvement in mobility, and has the potential to restore and maintain the sphericity of the femoral head after collapse. The high failure rate (27%) at short-term followup, although comparable with other reported techniques, does not support generalized use for Stage III disease. Currently the use of this procedure is restricted to symptomatic, young patients (younger than 40 years), preferably with mild to moderate Stage III disease (degree of head involvement < 30% and degree of collapse < 4 mm).
