Anterior shoulder instability is a common orthopaedic condition that often involves damage to the bony architecture of the glenohumeral joint in addition to the capsulolabral complex. Patients with recurrent shoulder dislocations are at increased risk for glenohumeral bone loss, as each instability event leads to the accumulation of additional glenoid and/or humeral head bone defects. Depending on the degree of bone loss, successful treatment may need to address bony lesions in addition to injured soft-tissue structures. As such, a thorough understanding of methods for evaluating bone loss preoperatively, in terms of location, size, and significance, is essential. Although numerous imaging modalities can be used, three-dimensional imaging has proven particularly useful and is now an integral component of preoperative planning.
肩关节前向不稳定是一种常见的骨科疾病，除了肩袖盂唇复合体外，通常还涉及盂肱关节的骨结构损伤。复发性肩关节脱位患者发生肱骨头和（或）肩胛盂骨缺损的风险增加，因为每次不稳定事件都会导致更多的盂唇和/或肱骨头骨缺损。根据骨丢失的程度，成功的治疗可能需要解决骨病变，除了受伤的软组织结构。因此，术前彻底了解评估骨丢失的方法，包括位置、大小和意义，是至关重要的。尽管有许多影像学方法可以使用，但三维成像已被证明特别有用，现在是术前规划的一个组成部分。
