Proximal radial fractures are a common type of fracture around the elbow joint. Among these comminuted radial head fractures are commonly associated with secondary injuries and instability of the elbow joint. Management of the radial head in such cases is very important in restoring the stability of the elbow joint and starting early mobilization. The aim of this study was to find out the prevalence of radial head arthroplasty among patients with radial head fracture in a tertiary care centre.
A descriptive cross-sectional study was conducted from 25 January 2019 to 25 December 2020 among patients with a radial head fracture at the Department of Orthopaedics of a tertiary care centre. Ethical approval was obtained from the Institutional Review Committee (Reference number: 076/77-08A). A convenience sampling method was used. The study group consisted of patients between 20 to 60 years of age with isolated radial head fractures. Radial head arthroplasty was done for Mason types III and IV fractures and functional outcome was calculated postoperatively with Mayo elbow score on follow-up at 3-, 6- and 12-month intervals. Point estimate and 95% Confidence Interval were calculated.
Out of 96 patients with radial head fracture, 22 (22.92%) (17.59-28.25, 95% Confidence Interval) underwent radial head arthroplasty. The mean Mayo elbow score was 96.33±7.74 at 12 months of follow-up.
The prevalence of radial head arthroplasty among irreparable radial head fractures was similar compared to other studies done in a similar setting.

桡骨头骨折是肘关节周围常见的骨折类型。其中，粉碎性桡骨头骨折常伴有肘部的继发性损伤和不稳定。在这种情况下，处理桡骨头对于恢复肘关节的稳定性和早期开始活动非常重要。本研究旨在探讨在一家三级保健中心，桡骨头骨折患者行桡骨头置换术的发生率。
2019 年 1 月 25 日至 2020 年 12 月 25 日，在一家三级保健中心的骨科，对桡骨头骨折患者进行了一项描述性的横断面研究。本研究获得了机构审查委员会的伦理批准（编号：076/77-08A）。采用方便抽样法。研究组由年龄在 20 至 60 岁之间、单纯桡骨头骨折的患者组成。对 Mason 类型 III 和 IV 型骨折行桡骨头置换术，术后通过 Mayo 肘评分评估功能恢复情况，并在术后 3、6 和 12 个月的随访时进行。计算点估计值和 95%置信区间。
在 96 例桡骨头骨折患者中，有 22 例（22.92%）（95%置信区间为 17.59-28.25）接受了桡骨头置换术。12 个月随访时的平均 Mayo 肘评分（MESS）为 96.33±7.74。
在不可修复的桡骨头骨折患者中，桡骨头置换术的发生率与在类似环境下进行的其他研究相似。
