Distal humerus hemiarthroplasty is a good surgical option for nonreconstructable intraarticular distal humerus fractures in selected lower-demand patients. The lifetime activity restrictions have not been determined, but are likely less than a total elbow arthroplasty. From a technical standpoint, distal humeral prostheses should be implanted at the correct depth and rotation. The collateral ligaments, condyles, and epicondyles should be preserved and/or repaired to maintain joint stability. Short- to midterm retrospective studies have shown promising results.
对于部分需求较低的患者，不可重建的肱骨远端关节内骨折，肱骨远端半关节置换术是一种不错的手术选择。目前尚未确定其终身活动限制，但可能比全肘关节置换术要少。从技术角度来看，肱骨远端假体应植入正确的深度并进行正确的旋转。应保留和/或修复侧副韧带、髁和上髁以维持关节稳定性。短期至中期的回顾性研究已显示出有前景的结果。
