ABSTRACT
INTRODUCTION:
Custom acetabular components are an increasingly utilized reconstructive option in total hip arthroplasty for catastrophic bone loss and acetabular failure. The purpose of this study was to determine the survivorship of such components for reconstruction due to catastrophic bone loss at a minimum 5-year follow-up.METHODS:
From August 2003 to July 2016, 64 patients (66 hips) underwent acetabular reconstruction with custom triflange components. All hips were classified as Paprosky 3B or 3C. Harris hip scores were analyzed. Overall survivorship was determined by survival analysis.RESULTS:
Seventeen patients (18 hips) died prior to returning for 5-year follow-up. One presumed living patient was lost to contact, yielding a cohort of 46 patients (47 hips) who had minimum 5-year follow-up. The mean age was 65 years (range, 46 to 85), mean body mass index was 29.4 (range, 18 to 45), and 72% were women. Mean follow-up was 8 years (range, 5 to 16). There were 3 revisions of the triflange device (6.4%) due to infection. Survivorship to end point of triflange removal for any reason was 94.1% (95% confidence interval ±3.4%) at a mean of 16 years. In the overall series (n = 66), there were 9 (13.6%) additional reoperations as follows 5 incision and debridements, one open reduction internal fixation, two stem revisions for periprosthetic femoral fracture, and one head revision. Harris hip scores improved significantly from a mean of 41 points preoperatively to 64 points postoperatively.CONCLUSIONS:
Custom acetabular triflange components represent a highly effective tool in a surgeon's armamentarium. These devices are extremely helpful in managing catastrophic bone loss and have a good mean 16-year survival.Palabras clave
