Fractures of the distal clavicle represent 15-30% of all clavicle fractures. The local osseoligamentous anatomy and deforming forces result in increased risk of delayed union and nonunion than fractures in other parts of the clavicle. These factors also contribute to challenges in fracture repair. Understanding these injuries and their imaging features enhances care and ensures patients are directed to appropriate management. We review the anatomy of the distal clavicle and surrounding ligaments, options for radiographic evaluation, relevant classification systems, and current concepts in management. Illustrative examples of specialized views are provided. Pediatric acromioclavicular joint pseudosubluxation is also reviewed, with findings specific to that injury.
锁骨远端骨折占所有锁骨骨折的15% - 30%。与锁骨其他部位的骨折相比,局部骨韧带解剖结构及致伤力导致延迟愈合和不愈合的风险增加。这些因素也给骨折修复带来了挑战。了解这些损伤及其影像学特征有助于提高治疗效果,并确保患者得到恰当的治疗。我们回顾了锁骨远端及其周围韧带的解剖结构、影像学评估方法、相关分类系统以及当前的治疗理念。文中提供了特殊视图的示例。还对小儿肩锁关节假性半脱位进行了回顾,并阐述了该损伤的特异性表现。
