摘要
目的研究使用混合型与生物型假体的全髋关节置换术(THA)术后异位骨化(HO)的情况。方法回顾性研究自2004年1月～2010年1月行初次单侧人工THA患者,从中配对选取76对,配对的参数为年龄、性别、体重。A组患者行混合型人工THA,B组患者行生物型人工THA。HO诊断依据术后3个月和12个月的髋关节前后位X线片,按Brooker分级记录。结果 A组发生HO的例数为21例,总发生率27.63%,B组发生HO例数为30例,总发生率为39.47%,两者差异无统计学意义。结论混合型与生物型人工THA术后HO的发生率没有明显差异。
Objective To compare the frequency of heterotopic ossification in patients with avascular necrosis of femoral head who underwent combination or biotype total hip arthroplasty. Methods Seventy six patients who underwent combination prosthesis （cohort A） individually matched 76 patients with biotype prosthesis （cohort B）. The match parameters were age （＋5 years）, Sex and weight （＋10 kg）. The radiographs at 3 months and 12 months after the operation were used to evaluate the heterotopie ossification by Brooker classification. Re- suits There were 21 cases of HO in cohort A, while 30 cases in cohort B. The ratio of HO was 27.63% and 39.47% respectively. Con- clusion There are no significant statistic differences in the prevalence of heterotopic ossification between combination and biotype total hip arthroplasty in patients with avascular necrosis of femoral head. Fear of heterotopic ossification should not be a factor in the choice of fLxation for THA.
