Seven hundred thirty-two total hip replacements performed from 1970 to 1980 were evaluated for the degree of heterotopic bone formation postoperatively and its effect on long-term mechanical loosening. There were 231 Charnley total hip replacements, of which 152 had no heterotopic bone formation, 58 had Grade 1 formation, and 21 had Grade 2 or 3 formation. Among the 123 Mueller total hip replacements, 98 had no heterotopic bone formation, 19 had Grade 1 formation, and 6 had Grade 2 or 3 formation. For the 378 T-28 total hip replacements, there were 305 with no heterotopic bone formation, 59 with Grade 1 formation, and 14 with Grade 2 or 3 formation. Survival analyses using the definition of failure as loosening, fracture, or revision of the acetabulum or femoral components were constructed. There was no correlation between mechanical loosening, fracture, or revision of the total hip replacement and any degree of heterotopic bone formation.
对1970年至1980年期间进行的732例全髋关节置换手术进行评估，以确定术后异位骨形成的程度及其对长期机械性松动的影响。其中有231例Charnley全髋关节置换手术，其中152例没有异位骨形成，58例有1级形成，21例有2级或3级形成。在123例Mueller全髋关节置换手术中，98例没有异位骨形成，19例有1级形成，6例有2级或3级形成。对于378例T - 28全髋关节置换手术，有305例没有异位骨形成，59例有1级形成，14例有2级或3级形成。构建了以髋臼或股骨部件松动、骨折或翻修为失败定义的生存分析。全髋关节置换的机械性松动、骨折或翻修与任何程度的异位骨形成之间均无相关性。
