A Rear View Of The Greater Tubercle Of The Humerus

Description

Rotating through a posterior (rear) perspective, the proximal humerus comes into view with the greater tubercle positioned lateral to the humeral head and just distal to the anatomical neck. The animation clarifies the contour transition from the articular surface to the tubercular region, while keeping the intertubercular sulcus (bicipital groove) anterior and the surgical neck inferior as consistent orientation cues. Along the posterior aspect of the greater tubercle, the insertional facets are implied as the surface turns under the viewer, with the teres minor footprint most posterior, in contrast to the more superior and anterior facets for supraspinatus and infraspinatus. Bony landmarks stay readable. These relationships matter whenever you are trying to localize rotator cuff attachment and injury patterns on the proximal humerus. Greater tuberosity fractures and avulsions often accompany anterior shoulder dislocation, and the degree of superior and posterior displacement of a greater tubercle fragment tracks with pull from supraspinatus and infraspinatus, changing the subacromial clearance and postoperative rehabilitation constraints. A moving posterior view helps learners map tendon footprints to palpable and radiographic landmarks, something a single still frame rarely conveys with the same clarity. Use this sequence in upper limb anatomy teaching, orthopedic lecture decks on proximal humerus fractures and rotator cuff tears, or as a brief orientation clip in surgical education for deltopectoral versus posterior approaches when discussing tuberosity reduction and fixation. It also fits radiology correlation modules when pairing with Grashey, scapular Y, or axillary lateral projections to explain why the greater tubercle profile shifts with rotation.
