Shoulder arthroplasty is a rapidly improving and utilized management for end-stage arthritis that is associated with improved functional outcomes, pain relief, and long-term implant survival. Accurate placement of the glenoid and humeral components is critical for improved outcomes. Traditionally, preoperative planning was limited to radiographs and 2-dimensional computed tomography (CT); however, 3-dimensional CT is becoming more commonly utilized and necessary to understand complex glenoid and humeral deformities. To further increase accurate component placement, intraoperative assistive devices-patient-specific instrumentation, navigation, and mixed reality-minimize malpositioning, increase surgeon accuracy, and maximize fixation. These intraoperative technologies likely represent the future of shoulder arthroplasty.
肩关节置换术是一种用于治疗终末期关节炎的快速发展和应用的方法，它可以改善功能结局、减轻疼痛和提高长期植入物的存活率。准确放置肩胛盂和肱骨头组件对于改善结果至关重要。传统上，术前规划仅限于 X 线片和二维计算机断层扫描（CT）；然而，三维 CT 正变得越来越常用，对于理解复杂的肩胛盂和肱骨头畸形是必要的。为了进一步提高组件放置的准确性，术中辅助设备——患者特异性器械、导航和混合现实——可以最大限度地减少错位，提高外科医生的准确性，并最大限度地固定。这些术中技术可能代表了肩关节置换术的未来。
