In order to delineate groups of patients suitable for treatment to prevent heterotopic bone formation (HBF) following total hip replacement, 99 patients were examined to evaluate predisposing factors. One year after surgery, HBF was found in 73% of the patients. A significantly increased frequency of HBF was found among men. There was no correlation between age, severity of osteoarthritis, size of osteophytes, or preoperative hip movement and HBF. Previous ipsilateral hip surgery did not increase the risk of HBF. Although not significant, all patients who developed heterotopic bone after previous ipsi- or contralateral hip surgery showed HBF of the same or even a higher grade after the present replacement.
为了确定适合进行预防全髋关节置换术后异位骨形成（HBF）治疗的患者群体，对99例患者进行了检查以评估诱发因素。术后一年，73%的患者出现了HBF。男性中HBF的发生率显著增加。年龄、骨关节炎严重程度、骨赘大小或术前髋关节活动度与HBF之间无相关性。既往同侧髋关节手术并未增加HBF的风险。尽管差异不显著，但所有在既往同侧或对侧髋关节手术后发生异位骨的患者在本次置换术后均出现了相同或更高等级的HBF。
