clinical anatomy of humerus

These fossæ are separated from one another by a thin, transparent lamina of bone, which is sometimes perforated by a supratrochlear foramen; they are lined in the fresh state by the synovial membrane of the elbow-joint, and their margins afford attachment to the anterior and posterior ligaments of this articulation. The coronoid fossa is smaller than the olecranon fossa and receives the coronoid process of the ulna during maximum flexion of the elbow. The posterior surface appears somewhat twisted, so that its upper part is directed a little medialward, its lower part backward and a little lateralward. Eur J Radiol.

STUDY. Hand AP View. Proximal humerus fractures are common injuries. Due to the clavicle’s structure, there are only two planar diarthrosis articulations that can be found. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa). The Medial supracondylar crest forms the sharp medial border of the distal humerus continuing superiorly from the medial epicondyle. Above and in front it presents an impression for the insertion of the tendon of the subscapularis muscle. Between the condyles, the bone thins, and the recess created is the coronoid fossa. In the fresh state its upper part is covered with a thin layer of cartilage, lined by a prolongation of the synovial membrane of the shoulder-joint; its lower portion gives insertion to the tendon of the latissimus dorsi muscle. In most living tetrapods, however, the humerus has a similar form to that of humans. Home. Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. Posterior view.

The Lateral Supracondylar crest forms the sharp lateral border of the distal humerus continuing superiorly from the lateral epicondyle.[3]. Humerus. [citation needed]. It is directed upward, medialward, and a little backward, and articulates with the glenoid cavity of the scapula to form the glenohumeral joint (shoulder joint). Shoulder Reconstruction. Upper Limb Index. In addition, the anatomy and biomechanics are described from their functional perspective as passive and active stabilizers. In contrast, the subscapularis muscle inserts onto the lesser tubercle and works to medially, or internally, rotate the humerus.
