The coracoclavicular ligaments vary widely in morphology and anatomic descriptions. Few authors have adequately described the coracoclavicular ligaments' anatomy, and a number of discrepancies exist in the anatomy literature. This study examines the complex anatomy of the coracoclavicular ligaments and their relationships to clinically important bony landmarks. The geometric dimensions of 24 coracoclavicular ligament specimens from fresh human cadaveric shoulders were examined and quantified with 13 different measurements. Particular attention was given to any inter-specimen anatomic variance. The coracoid insertions of the conoid ligaments displayed high variance, with 33% (8/24) being confluent with the lateral fibers of the superior transverse scapular ligament. A further 15% (3/24) presented an additional lateral fascicle. The distance from the lateral trapezoid ligament to the distal clavicle averaged 15.3 mm. Three distinct and previously unreported conoid ligament variants lend themselves to an anatomic classification (types I, II, and III). A safety margin of 15 mm is suggested for distal clavicle resection in incomplete acromioclavicular joint injuries to preserve the intact coracoclavicular ligament.
喙锁韧带在形态和解剖描述上差异很大。很少有作者充分描述过喙锁韧带的解剖结构，解剖学文献中存在一些差异。本研究探讨了喙锁韧带的复杂解剖结构及其与临床上重要骨性标志的关系。对取自新鲜人类尸体肩部的24个喙锁韧带标本的几何尺寸进行了检查，并用13种不同的测量方法进行了量化。特别关注了标本间的解剖变异情况。锥状韧带的喙突附着处变异很大，33%（8/24）与肩胛上横韧带的外侧纤维融合。另有15%（3/24）有额外的外侧束。从外侧梯形韧带到锁骨远端的平均距离为15.3毫米。三种不同且此前未报道过的锥状韧带变异型可进行解剖学分类（I型、II型和III型）。对于不完全肩锁关节损伤，建议在切除锁骨远端时保留15毫米的安全 margin 以保护完整的喙锁韧带。 （注：原文中“margin”未明确中文释义，可根据语境理解为“边缘、余量”等意思，这里暂保留英文，以便根据具体医学背景准确理解）
