humeroglenoide

Humeroglenoide is a term encountered in some anatomical and radiological texts to describe the interface between the humerus and the glenoid cavity of the scapula. The combination of humerus (humeral) and glenoid (glenoid) with the suffix -oid suggests a relationship to the humero-glenoid region, effectively referring to the glenohumeral articulation.

In standard anatomical usage, the articulation between the humeral head and the glenoid fossa is called the glenohumeral joint. The humeral head is a ball-like structure that fits into the shallow, pear-shaped glenoid fossa. The glenoid labrum—a fibrocartilaginous rim—deepens the socket and enhances stability. The joint capsule, reinforced by glenohumeral ligaments and the coracohumeral ligament, provides passive stability, while the rotator cuff tendons (supraspinatus, infraspinatus, teres minor, and subscapularis) offer dynamic stabilization.

Clinical relevance often centers on injuries and disorders of the glenohumeral articulation, such as dislocations, rotator cuff pathology, labral tears, and degenerative arthritis. Imaging studies, including X-ray and MRI, evaluate the integrity of the humero-glenoid interface and surrounding soft tissues. Nevertheless, in formal anatomy references, the term humeroglenoide is not a standard designation; the preferred terminology remains glenohumeral joint or humero-glenoid articulation when describing this region.
