The aim of this study is to investigate the population and primary total hip arthroplasty (THA)-based incidences, fracture types, complications, and survival of operatively treated periprosthetic femoral fracture (PFF).
This retrospective study reviewed 202 cases of operatively treated PFFs in a study period from January 2004 to December 2016. The Vancouver classification was used to classify PFFs.
The incidence of PFF related to 1000 primary THAs per year was 2.7 (standard deviation 1.0, range 0.9-4.5) at a defined hospital district area during the study period. The mean population-based incidence of operatively treated PFFs raised from 1.6 to 4.5 per 100,000 person-years during the study period. The B1-type fracture was the most common fracture type in 71 of 202 (35%) of these PFFs. The cumulative incidence of re-revision was 10.9% at 1 year and 15.6% at 15 years (95% confidence interval [CI] 10.9-21.0). The cumulative incidence for other major complications was 6.4% at 1 year and 9.9% at 15 years (95% CI 5.9-15.0). The cumulative incidence of death after PFF was 7.4% at 1 year and 56.3% at 15 years (95% CI 41.3-68.8) during the follow-up time from January 1, 2004 to December 31, 2019.
This country-specific study showed a 3-fold increasing trend in the incidence of operatively treated PFFs from 2004 to 2016 per 1000 THAs. The Vancouver type B1 fracture was the most common type. A high number of complications were associated with PFFs and 7.4% of the patients had died within 1 year after PFF surgery.
本研究旨在探讨人群和原发性全髋关节置换术（THA）基础发病率、骨折类型、并发症和假体周围股骨骨折（PFF）手术治疗的生存率。
本回顾性研究回顾了 2004 年 1 月至 2016 年 12 月期间接受手术治疗的 202 例 PFF 病例。采用温哥华分类法对 PFF 进行分类。
在研究期间，定义的医院区域内，每 1000 例原发性 THA 中 PFF 的发生率为 2.7（标准差 1.0，范围 0.9-4.5）。人群发病率从研究期间的每 100000 人年 1.6 例上升至 4.5 例。202 例 PFF 中，B1 型骨折最常见，占 71 例（35%）。1 年时再翻修率为 10.9%，15 年时为 15.6%（95%置信区间 [CI] 10.9-21.0）。其他主要并发症的 1 年累积发生率为 6.4%，15 年时为 9.9%（95%CI 5.9-15.0）。PFF 后 1 年死亡率为 7.4%，15 年时为 56.3%（95%CI 41.3-68.8），随访时间为 2004 年 1 月 1 日至 2019 年 12 月 31 日。
本研究表明，2004 年至 2016 年，每 1000 例 THA 中手术治疗的 PFF 发病率增加了 3 倍。温哥华 B1 型骨折是最常见的类型。PFF 相关并发症较多，7.4%的患者在 PFF 手术后 1 年内死亡。
