摘要
目的:研究骨水泥的应用对全髋关节置换术(THA)后异位骨化(HO)发生率的影响。方法:回顾性分析283髋的初次THA后HO发生情况,其中生物型194髋,混合型(骨水泥型股骨柄,生物型髋臼)89髋,临床和影像的平均随访时间为36个月(12~60个月),诊断主要依据髋关节前后位X线片,按Brooker分级进行分级记录,运用单因素卡方检验比较生物型和混合型假体HO的发生率差异。结果:283例髋中共69髋发生HO,发生率为24.4%,没有发现BrookerⅣ型。194例生物型髋中48髋发生HO,发生率为24.7%,其中Brooker I型34例(占17.5%),Brooker II型9例(占4.6%),Brooker III型5例(占2.6%);89例混合型髋中21例发生HO,发生率为23.6%,其中Brooker I型16例(占18.0%),Brooker II型3例(占3.4%),Brooker III型2例(占2.2%),两组HO发生率及严重HO发生率差异均无统计学意义(Ρ值分别为0.835和0.868)。结论:生物型与混合型假体HO发生率差异无统计学意义,骨水泥的应用对术后HO发生率无明显影响。
Objective: To study the effect of the application of bone cement on the incidence of heterotopic ossification (HO) following total hip arthroplasty (THA). Methods: Retrospectively evaluated 283 hips undergoing primary THA. There were 194 noncemented hips and 89 hybrid (combination of cemented stem and noncemented acetabular cup) hips. Follow-up ranged from 12 to 60 months (mean 36 months). Diagnosis was mainly based on anteroposterior X-rays of hips, according to the criteria of Brooker. The data was analyzed by chi-square test of independence. Results: Overall, the incidence of HO was 24.4% (n=69), which was graded as Brooker I for 17.7% (n=50), Brooker Ⅱ for 4.2% (n=12), Brooker Ⅲ for 2.5% (n=7), and there was no Brooker IV. Forty-eight (24.7%) hips had HO in noncemented THA, 34(17.5%) were Brooker I, 9(4.6%) were Brooker Ⅱ, 5(2.6%) were Brooker Ⅲ. However, 21 (23.6%) hips had HO in hybrid THA, 16(18%) were Brooker I, 3(3.4%) were Brooker Ⅱ, 2(2.2%) were Brooker Ⅲ Therefore, there was no significant statistical difference on the prevalence of HO or severely HO between the noncemented THA and hybrid THA (P=0.835 and P=0.868). Conclusion: The application of bone cement does not influence the prevalence of HO following THA.
