Long-term follow-up after intertrochanteric varus osteotomy for haemophilic arthropathy of the hip

In view of an increasing tendency in prosthetic management of haemophilic arthropathy, we intended to evaluate the efficacy of corrective osteotomy of the hip, specifically taking long-term clinical and radiographic results into consideration. Eleven hips affected by haemarthropathy in nine patients suffering from severe haemophilia A were treated with an intertrochanteric varus osteotomy. The average follow-up period was 15.4 years. The preoperative clinical score of the Advisory Committee of the World Federation of Haemophilia was 5.3 points (range 4-7) and the Pettersson score was 6.4 points (range 2-10). The average WFH score at follow-up had increased to 3.6 points. Seven hips showed clinical improvement, two hips showed a postoperative deterioration while a further two hips remained unchanged. The Petterson score increased to an average of 7.7 points. Here the radiographs of six patients indicated postoperative deterioration, three remained unaltered and two showed improvement. Our study cannot conclusively answer whether intertrochanteric varus osteotomy for haemophilic arthropathy of the hip is always a feasible alternative to joint arthroplasty. The decision for or against this procedure must be individually assessed and the patient must be thoroughly informed about the advantages and disadvantages of both procedures.
