Uncemented Arthroplasty for Metastatic Disease of the Hip : Preliminary Clinical Experience

Improved longevity among patients with metastatic bone disease led to increasing incidence of pathologic and impending fractures around the hip. Cemented hip arthroplasty is considered to be the standard of care for this condition. The purpose of this study is to evaluate the outcome of uncemented hip arthroplasty in those patients. We performed a retrospective review of clinical and radiologic data of 57 consecutive patients (60 hips) who underwent an uncemented hip arthroplasty due to metastatic hip disease. Mean follow-up was 18.6 months (range, 5-60 months); overall 1-year survival and mortality rates were 58.5% and 38.3%, respectively. Multiple myeloma and metastatic prostate carcinoma patients had better outcome over other metastasis origin. At last follow-up, no prosthesis failure or operation-related major complication has been recorded.
