目的：使用透视控制X线摄影描述慢性肩关节前不稳定伴发骨性病变的发生率。研究类型：慢性肩关节前不稳定患者的影像学结果的病例系列。研究方法：回顾性评价了156例复发性肩关节前不稳定患者的160个肩关节的X线片; 132个肩关节出现复发性脱位，18个肩关节出现复发性半脱位，10个肩关节在关节镜检查时显示前不稳定证据，尽管没有报告不稳定病史。透视控制的放射学视图包括肱骨头旋转3次的前后视图和肩盂轮廓视图以及对侧肩关节的比较视图。结果：在160个肩关节中，117个（73.1%）在前后位X线片上发现肱骨撞击骨折。肩盂侧位显示160个肩关节中有126个（78.8%）肩盂骨质病变。前后位X线片显示另外13个肩关节（8.2%）的关节盂骨质病变。总体而言，在160个肩关节中的152个（95.0%）中发现了肱骨或关节盂骨病变。结论：这项研究表明，在肩关节前不稳定的患者中，经常出现骨性病变。
Purpose: To describe the incidence of bony lesions accompanying chronic anterior shoulder instability using fluoroscopically controlled radiography. Type of Study: Case series of radiographic findings of patients with chronic anterior shoulder instability. Methods: Radiographs of 160 shoulders in 156 patients with recurrent anterior shoulder instability were retrospectively evaluated; 132 shoulders had experienced recurrent dislocations, 18 shoulders had experienced recurrent subluxations, and 10 shoulders showed evidence of anterior instability at arthroscopy despite no reported history of instability. Fluoroscopically controlled radiographic views included an anteroposterior view with the humeral head in 3 rotations and a glenoid profile view with a comparison view of the contralateral shoulder. Results: A humeral impaction fracture was identified on the anteroposterior radiographs in 117 of 160 shoulders (73.1%). The glenoid profile view showed an osseous lesion of the glenoid in 126 of 160 shoulders (78.8%). The anteroposterior radiograph showed an osseous lesion of the glenoid in an additional 13 shoulders (8.2%). Overall, an osseous lesion, either humeral or glenoid, was identified in 152 of 160 shoulders (95.0%). Conclusions: This study shows the frequent presence of bony lesions in patients with anterior shoulder instability.
