The Anatomical Characteristics Of The Supraspinous Fossa Of The Scapula

Description

Arising on the posterior surface of the scapula, the supraspinous fossa occupies the shallow concavity superior to the spine of the scapula and inferior to the superior border, tapering laterally toward the root of the acromion. As the animation progresses, the scapular spine stands out as a strong transverse ridge separating supraspinous from infraspinous fossae, while the medial (vertebral) border and lateral (axillary) border frame the fossa’s gentle curvature. The sequence typically reveals the supraspinatus muscle bed within the fossa and its lateral course deep to the acromion toward the greater tubercle of the humerus. Bony topography stays readable throughout. Clinically, this region matters because the supraspinatus tendon is the most frequent site of rotator cuff degeneration and tearing, often at its footprint on the greater tubercle after chronic subacromial impingement beneath the coracoacromial arch. Animated rotation around the scapular spine and acromion clarifies how the fossa’s orientation relates to the subacromial space and why small changes in scapular tilt or acromial morphology can influence tendon abrasion during elevation. That spatial logic is hard to teach with a single posterior view. Use this animation in gross anatomy and kinesiology modules on the shoulder girdle, in orthopaedic and sports medicine lectures on rotator cuff pathology, and in publisher figures that need a clean bony landmark reference for MRI correlation (supraspinatus muscle belly in the supraspinous fossa, tendon coursing laterally). It also works well for patient-facing education that explains why posterior scapular pain can reflect supraspinatus overload rather than a primary scapular lesion.
