Introduction The purpose of this retrospective review was to identify risk factors associated with removal or revision following radial head arthroplasty. Methods Patients undergoing primary radial head arthroplasty between 2009 and 2015 with a minimum follow-up of 1 year were identified. Descriptive and bivariate statistics were used to analyze the characteristics of patients requiring implant removal or revision and multivariable analysis was performed to calculate hazard ratios. Results There were 312 patients included in the final cohort with a median follow-up of 3.8 years. Thirty-five patients (11.2%) underwent prosthesis removal or revision. There was an increased percentage of implants removed or revised in patients under age 40, with surgery performed for chronic indications compared to acute trauma, and with the use of press-fit stems compared to polished. Discussion It appears younger patient age, chronic surgical indications, and certain aspects of prosthesis design may influence rates of removal or revision.
介绍 本回顾性研究旨在确定与桡骨小头置换术后假体取出或翻修相关的风险因素。 方法 确定了 2009 年至 2015 年间接受初次桡骨小头置换术且随访时间至少 1 年的患者。采用描述性和双变量统计分析来分析需要进行植入物取出或翻修的患者的特征，并进行多变量分析以计算风险比。 结果 最终队列中包括 312 名患者，中位随访时间为 3.8 年。有 35 名患者（11.2%）进行了假体取出或翻修。在年龄小于 40 岁的患者中，接受慢性手术指征的患者，以及使用压配合式柄而不是抛光柄的患者中，假体取出或翻修的比例更高。 讨论 似乎年轻患者的年龄、慢性手术指征以及假体设计的某些方面可能会影响取出或翻修的发生率。
