The effects of lateral approaches for total hip arthroplasty on heterotopic bone formation were studied in 264 patients with primary osteoarthritis. The Hardinge approach was used in 82 patients, the transtrochanteric approach in 94, and the Liverpool approach in 88. The incidence of heterotopic ossification was 42%. A severe form of bone formation occurred five times more in the Liverpool approach than in other two approaches.
在264例原发性骨关节炎患者中，研究了全髋关节置换术外侧入路对异位骨形成的影响。82例患者采用Hardinge入路，94例采用经转子入路，88例采用利物浦入路。异位骨化的发生率为42%。严重骨形成形式在利物浦入路中出现的次数比其他两种入路多五倍。
