Abstract

We studied the frequency and patient risk factors for postoperative periprosthetic fractures after primary total hip arthroplasty (THA). With a mean follow-up of 6.3 years, 305 postoperative periprosthetic fractures occurred in 14,065 primary THAs. In multivariable-adjusted Cox regression analyses, female gender (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.17-1.88), Deyo-Charlson comorbidity score of 2 (HR, 1.74 for score of 2; 95% CI, 1.25-2.43) or 3 or higher (HR, 1.71; 95% CI, 1.26-2.32), and American Society of Anesthesiologist class of 2 (HR, 1.84; 95% CI, 0.90-3.76) or 3 (HR, 2.45; 95% CI, 1.18-5.1) or 4 or higher (HR, 2.68; 95% CI, 0.70-10.28) were significantly associated with higher risk/hazard, and cemented implant, with lower hazard (HR, 0.68; 95% CI, 0.54-0.87) of postoperative periprosthetic fractures. Interventions targeted at optimizing comorbidity management may decrease postoperative fractures after THA.

摘要

我们研究了初次全髋关节置换术后(THA)假体周围骨折的频率和患者危险因素。平均随访 6.3 年,在 14065 例初次 THA 中发生了 305 例术后假体周围骨折。在多变量调整的 Cox 回归分析中,女性性别(风险比 [HR],1.48;95%置信区间 [CI],1.17-1.88)、Deyo-Charlson 合并症评分 2 分(HR,1.74;95%CI,1.25-2.43)或 3 分或更高(HR,1.71;95%CI,1.26-2.32)和美国麻醉医师协会(ASA)分级 2 分(HR,1.84;95%CI,0.90-3.76)或 3 分(HR,2.45;95%CI,1.18-5.1)或 4 分或更高(HR,2.68;95%CI,0.70-10.28)与更高的风险/危险显著相关,而骨水泥固定假体与较低的假体周围骨折危险相关(HR,0.68;95%CI,0.54-0.87)。针对优化合并症管理的干预措施可能会降低 THA 后的术后骨折风险。
