To describe the incidence of bony lesions accompanying chronic anterior shoulder instability using fluoroscopically controlled radiography.
Case series of radiographic findings of patients with chronic anterior shoulder instability.
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.
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%).
This study shows the frequent presence of bony lesions in patients with anterior shoulder instability.
使用荧光透视控制的放射摄影描述伴有慢性前肩不稳的骨病变发生率。
慢性前肩不稳患者放射学表现的病例系列。
回顾性评估156例复发性前肩不稳患者的160个肩部的X线片；132个肩部有复发性脱位，18个肩部有复发性半脱位，10个肩部在关节镜检查时显示有前不稳迹象，尽管没有不稳定病史报告。荧光透视控制的放射学视图包括肱骨头部在3个旋转位置的前后位视图以及对侧肩部对比视图的肩胛盂轮廓视图。
在160个肩部中的117个（73.1%）的前后位X线片上发现肱骨撞击骨折。肩胛盂轮廓视图显示160个肩部中的126个（78.8%）有肩胛盂骨病变。前后位X线片在另外13个肩部（8.2%）显示有肩胛盂骨病变。总体而言，在160个肩部中的152个（95.0%）发现有肱骨或肩胛盂骨病变。
本研究表明前肩不稳患者中骨病变很常见。
