Anterior Perspective Of The Coracoclavicular Ligament

Description

Presented from an anterior shoulder perspective, the coracoclavicular ligament is shown spanning between the coracoid process of the scapula and the inferior surface of the lateral (acromial) end of the clavicle. The trapezoid ligament lies more anterolateral, running obliquely from the superior surface of the coracoid toward the trapezoid line of the clavicle, while the conoid ligament sits more posteromedial and vertically oriented toward the conoid tubercle. Adjacent landmarks logically visible in this setup include the acromion and glenoid of the scapula laterally, the proximal humerus inferiorly, and the acromioclavicular interval superficially. A key landmark. Coracoclavicular anatomy matters because it is the primary suspensory linkage between scapula and clavicle, and its integrity determines whether an acromioclavicular separation is stable (type I to II) or unstable with superior displacement of the clavicle (type III and above). Distinguishing the trapezoid from the conoid fibers also maps directly to reconstruction strategy, where surgeons aim to restore both bundles to control anteroposterior translation (trapezoid) and vertical stability (conoid) during coracoclavicular ligament reconstruction or hook plate alternatives. This anterior view also helps explain why coracoid-based fixation risks exist near the coracoid base, where hardware placement can endanger adjacent neurovascular structures in the deltopectoral interval and beneath the coracoid. Use this artwork in gross anatomy and musculoskeletal medicine courses to teach the clavicle to scapula relationship and the layered anatomy around the coracoid process, or in orthopedic and sports medicine publications discussing acromioclavicular joint injury classification and operative repair. It also supports preoperative counseling materials by clarifying where grafts, suture buttons, or anchors recreate the conoid and trapezoid components.
