The elbow joint is a hinge variety of synovial joint between the lower end of humerus and the upper ends of radius and ulna bones. Pain in this bump is called medial epicondylitis (also known as ‘golfer’s elbow’). The blood supply to the elbow joint is derived from a number of periarticular anastamoses that are formed by the collateral and recurrent branches of the brachial, profunda brachii, radial and ulnar arteries. It is bounded medially and laterally by collateral ligaments between the humerus and radius, caudally by the olecranon ligament between the humerus and olecranon, and further enforced by the annular radial ligament. ...

Blood supply. Based on our determination of the dominant blood supply to osseous and capsular elbow structures, we derived a cadaveric model of elbow VCA by performing donor preparation on 2 fresh cadaveric upper extremities by elevating a lateral arm flap in conjunction with the vascularized elbow joint. Blood supply The radiocarpal joint receives its blood supply from the branches of the dorsal and palmar carpal arches . Elbow joint is a term for humeroradial and humeroulnar joints. 14.

Mysositis ossificans is an unusual condition in which extraskeletal bone formation begins to form in the muscle, usually caused by trauma to the area, which most often occurs in the brachialis. So let’s start… The elbow joint is a hinge variety of a synovial joint between the lower end of humerus and the upper ends of radius and ulna bones. Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of the bone separates from the end of the bone because of inadequate blood supply. The articular and epiphyseal branches of the neighboring arteries form a periarticular arterial plexus. At the elbow, the brachial artery divides into: Ulnar artery with its branches, the superior and inferior ulnar collateral arteries, is located at the medial and anterior side of the forearm to reach the wrist. … Radial artery descends in the anterior and lateral side of the forearm. Blood supply predominant supply is the deep branch of the radial artery ; minor supply from the deep branch of the ulnar artery; Branches of the deep arch (from radial to ulnar) princeps pollicis.
