Three bones and two joints comprise the pectoral girdle. These are the clavicle, scapula, proximal humerus, acromioclavicular joint, and shoulder joint. The pectoral girdle binds the upper extremity to the torso. Thus, injury to any of the pectoral girdle's components can impact the function of the entire extremity. The spectrum of pectoral girdle injuries ranges from a simple acromioclavicular joint sprain to scapulothoracic dissociation. Whereas the former is a painful but self-limiting injury with minimal sequelae, the latter is life threatening. However, the severity of most pectoral girdle injuries lies between these two extremes. Fractures and dislocations are common in this region throughout life, and a clear understanding of the patterns of injury and their radiographic spectrum is essential for all radiologists who deal with trauma.
上肢带骨由三块骨头和两个关节组成。它们是锁骨、肩胛骨、肱骨近端、肩锁关节和肩关节。上肢带骨将上肢与躯干相连。因此，上肢带骨任何一个组成部分的损伤都会影响整个上肢的功能。上肢带骨损伤的范围从简单的肩锁关节扭伤到肩胛胸壁分离。前者是一种疼痛但自限性的损伤，后遗症极少，而后者则危及生命。然而，大多数上肢带骨损伤的严重程度介于这两个极端之间。骨折和脱位在该区域一生中都很常见，对于所有处理创伤的放射科医生来说，清楚了解损伤模式及其影像学表现至关重要。
