METHODS: We retrospectively reviewed all 4806 hip arthroplasties that was performed in a single institution from May 2003 to December 2020. Age at the index arthroplasty, sex, body mass index, physical status, ambulatory function, side of the operation, operational history, cause of the index arthroplasty, type of arthroplasty, surgical approach, surgeon, implant information, and events during the operation were investigated. The shoulder geometry and length of stem were also reviewed. The event of interest was narrowed down to IOPFx among various records of intraoperative events.
RESULTS: We found IOPFx of 2.6% among all the hips operated with cementless stem. In the multivariable analysis, female (OR = 1.52), childhood hip disease (OR = 2.30), stove-pipe femur (OR = 2.43), combined approach (OR = 2.60), and standard length of stem (OR = 1.59) were found to be significant risk factors of IOPFx.
CONCLUSIONS: In conclusion, a stem with a standard length is significantly associated with risk of IOPFx compared to a shortened stem. These findings highlight the importance of careful consideration in terms of the risk of IOPFx when standard length cementless stem is chosen.
方法:我们回顾性回顾了2003年5月至2020年12月在单个机构中进行的所有4806例髋关节置换术。索引关节成形术的年龄,性别,身体质量指数,身体状况,步行功能,行动的一面,运营历史,索引关节成形术的原因,关节成形术的类型,手术方法,外科医生,植入信息,并对手术过程中的事件进行了调查。还回顾了肩的几何形状和茎的长度。在各种术中事件记录中,感兴趣的事件缩小到IOPFx。
结果:我们发现,在所有使用无骨水泥茎手术的臀部中,IOPFx为2.6%。在多变量分析中,女性(OR=1.52),儿童髋关节疾病(OR=2.30),火炉管股骨(OR=2.43),组合方法(OR=2.60),和标准茎长度(OR=1.59)是IOPFx的重要危险因素。
结论:结论:与缩短的茎相比,具有标准长度的茎与IOPFx的风险显着相关。这些发现强调了在选择标准长度无水泥茎时仔细考虑IOPFx风险的重要性。
