This study examined the natural progression of pelvic osteolysis post uncemented total hip arthroplasty. Serial radiographs from 145 total hip arthroplasties with minimum 10-year follow-up were examined. Thirty-two lesions were identified in 25 hips and their 2-dimensional radiographic size over time was measured via computer. Lesion growth rate averaged 42.7 +/- 49.0 mm2/y. Linear models were generally a good fit for lesion growth as evidenced by a high mean r2 value (0.77 +/- 0.18); lesions progressed steadily during the first 10 postoperative years. Although lesions were first radiographically evident 5.7 years postarthroplasty, the x-intercept of the linear model, approximating the mean time when the lesions first began to develop, averaged 1.3 years. Because this study expands our understanding of when and how peri-acetabular lesions develop, it can be useful to clinicians in determining how often to see patients postoperatively. |
