Recurrent symptomatic sternoclavicular (SC) joint instability is rare and most commonly occurs following high-energy trauma or in patients with generalized ligamentous laxity. We report an unusual case of an atraumatic posterior subluxation of the SC joint, leading to a feeling of choking. The posterior subluxation, which occurred during shoulder motion and in supine body position, was demonstrated using a dynamic wide-volume 4-dimensional computed tomography scan. Based on continuing patient symptoms and imaging findings, surgical stabilization of the SC joint was undertaken.
复发性症状性胸锁关节（SC）不稳定很少见，最常见于高能创伤后或患有全身性韧带松弛的患者。我们报告了一例不寻常的无创伤性胸锁关节后脱位病例，该病例导致患者有窒息感。通过动态宽容积四维计算机断层扫描显示，后脱位发生在肩部运动和仰卧体位时。基于患者持续的症状和影像学检查结果，对胸锁关节进行了手术固定。
