This study aims to use the Dutch Arthroplasty Register data to report an overview of the contemporary indications and implant designs, and report the short-term survival of radial head arthroplasty.
From the Dutch Arthroplasty Register, data on patient demographics, surgery and revision were extracted for radial head arthroplasties performed from January 2014 to December 2019. Implant survival was calculated using the Kaplan-Meier method.
Two hundred fifty-eight arthroplasties were included with a median follow-up of 2.2 years. The most common indication was a fracture of the radial head (178, 69%). One hundred thirty-nine (68%) of the prostheses were of bipolar design, and the most commonly used implant type was the Radial Head System (Tornier; 134, 51%). Of the 258 included radial head arthroplasties, 16 were revised at a median of six months after surgery. Reason for revision was predominantly aseptic loosening (9). The overall implant survival was 95.8% after one year, 90.5% after three years and 89.5% after five years.
For radial head arthroplasties, acute trauma is the most common indication and Radial Head System the most commonly used implant. The implant survival is 89.5% after five years.
本研究旨在利用荷兰关节成形术登记数据报告当代手术适应症及植入物设计概况，并报告桡骨头置换术的短期生存率。
从荷兰关节成形术登记处提取2014年1月至2019年12月期间进行的桡骨头置换术的患者人口统计学、手术及翻修数据。采用Kaplan-Meier法计算植入物生存率。
纳入258例置换术，中位随访时间为2.2年。最常见的适应症是桡骨头骨折（178例，69%）。139例（68%）假体为双极设计，最常用的植入物类型是桡骨头系统（Tornier公司；134例，51%）。在258例纳入的桡骨头置换术中，16例在术后中位时间6个月时进行了翻修。翻修的主要原因是无菌性松动（9例）。1年时植入物总体生存率为95.8%，3年时为90.5%，5年时为89.5%。
对于桡骨头置换术，急性创伤是最常见的适应症，桡骨头系统是最常用的植入物。5年后植入物生存率为89.5%。
