Besides osteoarthritic changes, traumatic and posttraumatic lesions are the most frequent alterations of the acromioclavicular (AC) joint. The Rockwood classification is used to describe posttraumatic lesions. The most important screening modality is anteroposterior x‑ray imaging, preferably with weight bearing and side to side comparison. Magnetic resonance imaging (MRI) without weight bearing is superior to x‑rays in analyzing and classifying AC joint dislocations. Postoperative imaging and assessment of arthritic alterations are usually carried out using x‑ray images and MRI is used as an additional examination modality. Sonography is only of limited value. Multidetector computed tomography (MDCT) is usually not used as a primary imaging modality for the AC joint; however, it can be analyzed simultaneously whenever the shoulder joint is being investigated with MDCT.
除骨关节炎改变外，创伤性和创伤后病变是肩锁关节（AC）最常见的改变。Rockwood分类用于描述创伤后病变。最重要的筛查方式是前后位X线成像，最好是负重并进行双侧对比。非负重磁共振成像（MRI）在分析和分类肩锁关节脱位方面优于X线。术后关节炎改变的成像和评估通常使用X线图像，MRI用作辅助检查方式。超声检查的价值有限。多排螺旋计算机断层扫描（MDCT）通常不作为肩锁关节的主要成像方式；然而，在用MDCT检查肩关节时可同时对其进行分析。
