Conoid Ligament, Anterior View

Description

Prominent in this anterior shoulder view, the lateral clavicle is braced to the superior surface of the coracoid process by the conoid ligament, the medial and more vertically oriented component of the coracoclavicular ligament complex. Just lateral to it, the trapezoid ligament runs more obliquely from the coracoid toward the trapezoid line of the clavicle, together forming a paired suspension system between scapula and clavicle. Inferior to the clavicle, the proximal humerus and glenoid region of the scapula frame the glenohumeral joint, with adjacent ribs and costal cartilages establishing the upper thoracic wall as a spatial reference. Articular cartilage caps the humeral head and glenoid fossa. Clean landmarks. Coracoclavicular integrity is what keeps the scapula from “dropping” away from the clavicle when the upper limb is loaded, and the conoid is the main restraint to superior displacement of the clavicle and contributes to control of scapular upward rotation. This relationship matters in acromioclavicular (AC) joint separations, where conoid rupture produces the characteristic increase in coracoclavicular distance and higher-grade instability, often discussed alongside trapezoid involvement. For operative teaching, the anterior perspective helps clarify where suture-button constructs or grafts aim to recreate native conoid and trapezoid vectors relative to the coracoid base and the clavicular undersurface. Use this plate in gross anatomy and kinesiology teaching when introducing the pectoral girdle as a ring, not a single joint, and in orthopedic or sports-medicine materials explaining AC separation grading, radiographic coracoclavicular measurements, and coracoclavicular ligament reconstruction. It also suits surgical consent diagrams and device manuals that need a clear anterior map of the conoid ligament’s position against clavicle, scapula, and proximal humerus.
