Cementless total hip arthroplasty with structural allograft for massive acetabular defect in hip revision / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To study retrospectively 20 hip revison patients treated by cementless total hip arthroplasty with structural allograft.</p><p><b>METHODS</b>Twenty patients suffering from aseptic loosening of an uncemented cup complicated by a large defect underwent cementless total hip arthroplasty with structural allograft and were followed up for at least 5 years. Clinical results were evaluated by Harris score and leg length measurements. Radiographic analysis included implants migration, graft absorbance, osteolysis and liner wear.</p><p><b>RESULTS</b>No cup loosening or graft reabsorption was found at final follow-up. Clinical improvements in pain and functional status were demonstrated during the follow-up period. The mean Harris hip scores improved from 29 preoperatively (range 20-41) to 81 postoperatively (range 73-89).</p><p><b>CONCLUSION</b>Our study shows that cementless total hip arthroplasty with allograft is a good way for massive defect in acetabular bone stock.</p>
