Radial head fractures are some of the most common elbow fractures. Fractures with 3 or more fracture fragments have been shown to have worse outcomes when treated with open reduction and internal fixation (ORIF). Radial head replacement offers an alternative treatment for those more comminuted radial head fractures.
Three-part radial head fractures make anatomical reduction more difficult to obtain with ORIF. Radial head fractures requiring replacement have shown good clinical outcomes. As a result, radial head arthroplasty offers a good treatment option for 3-or-more-part radial head fractures.
This video presents a case of a radial head arthroplasty for a 3-part radial head fracture in a 23-year-old man. The radial head implant provides a smooth and concentric surface for articulation with the capitellum while providing stability to the elbow.
Radial head replacement provides a good alternative to ORIF, producing similar elbow range of motion and providing good stability compared with the contralateral elbow.
桡骨头骨折是最常见的肘部骨折之一。已经表明，对于 3 处或更多处骨折碎片的骨折，采用切开复位内固定（ORIF）治疗的效果较差。桡骨头置换为那些更粉碎性的桡骨头骨折提供了一种替代治疗方法。
三部分桡骨头骨折使得 ORIF 更难以实现解剖复位。需要置换的桡骨头骨折已经显示出良好的临床结果。因此，桡骨头关节成形术为 3 处或更多处桡骨头骨折提供了一种很好的治疗选择。
本视频介绍了一例 23 岁男性的 3 部分桡骨头骨折行桡骨头置换术的病例。桡骨头植入物为与肱骨小头的关节提供了一个光滑且同心的表面，同时为肘部提供了稳定性。
桡骨头置换为 ORIF 提供了一个很好的替代方法，与对侧肘部相比，产生相似的肘部活动范围，并提供良好的稳定性。
