- The elbow joint is where your humerus (your upper arm bone) meets your radius and ulna (the two bones in your forearm). It joins your upper arm to your forearm. Your elbow also contains cartilage, ligaments, muscles, nerves and blood vessels. Your elbow moves in two main directions. You use it almost any time you move your arm.

Sep 11, 2023 · The elbow joint is a synovial joint found in the upper limb between the arm and the forearm. It is the point of articulation of three bones: the humerus of the arm and the radius and the ulna of the forearm. The elbow joint is classified structurally as a synovial joint.

Subcutaneous bursitis: Repeated friction and pressure on the bursa can cause it to become inflamed. Because this bursa lies relatively superficially, it can also become infected (e.g cut from a fall on the elbow)
Subtendinous bursitis: This is caused by repeated flexion and extension of the forearm, commonly seen in assembly line workers. Usually flexion is more painful as more pressure is put on the bursa. An elbow dislocation usually occurs when a young child falls on a hand with the elbow flexed. The distal end of the humerus is driven through the weakes...
Most elbow dislocations are posterior, and it is important to note that elbow dislocations are named by the position of the ulna and radius, not the humerus.
Most of the flexor and extensor muscles in the forearm have a common tendinous origin. The flexor muscles originate from the medial epicondyle, and the extensor muscles from the lateral. Sportspersons can develop an overuse strain of the common tendon which results in pain and inflammation around the area of the affected epicondyle.
Direct damage, or swelling can cause the interference to the blood supply of the forearm via the brachial artery. The resulting ischaemia can cause Volkmanns ischaemic contracture uncontrolled flexion of the hand, as flexors muscles become fibrotic and short. There also can be damage to the medial, ulnar or radial nerves. As a result, the neurovas...

Jul 24, 2023 · The elbow is a synovial hinge joint made up of articulations of mainly the distal humerus and the proximal ulna. However, articulations exist between the proximal radius and the humerus as well as the proximal radius and ulna.

Sep 12, 2023 · Where is the Humeroulnar joint Located? The humeroulnar joint is one of the primary joints of the elbow complex. The elbow is situated between the upper arm and the forearm. Specifically, the humeroulnar joint is formed where the humerus of the upper arm meets the ulna of the forearm.
Three bones make up the elbow joint: the distal end of the humerus and the proximal ends of the ulna and radius. The ulna and the radius are both forearm bones. Their distal ends form the wrist joint.
The elbow joint is a complex hinge joint formed between the distal end of the humerus in the upper arm and the proximal ends of the ulna and radius in the forearm. The elbow allows for the flexion and extension of the forearm relative to the upper arm, as well as rotation of the forearm and wrist.
