The Elbow Joint Explained
Like the joints in your fingers the elbow is considered a hinge joint, which means that it allows for motion forward and back (flexion and extension) with very minimal twisting. The elbow joins together three bones, the humerus in the upper arm and the radius and ulna in the lower arm. The funny bone in your elbow is a large bony projection from the ulna called the olecranon. A membrane surrounds the entire joint with ligaments joining the three bones together. Two tendons, which attach the bones in your elbow to your muscle, are the primary facilitators or joint movement.
Potential Causes of Elbow Pain
There are quite a few reasons for pain to be occurring in your elbow. Sudden injury, repetitive motion, infections, inflammation, and diseases are all common causes of pain to the elbow.
Injuries can include fractures to the joint, sprains, strains, dislocation, and torn ligaments. Another potential injury related condition, called osteochondritis dissecans, occurs when a small piece of cartilage and bone is separated causing the potential for the elbow to lock in place. Elbow injuries usually occur following a sudden trauma, like hyperextension or impacts, as opposed to repetitive motion injuries and syndromes.
Infections In The Elbow
An infection can occur spontaneously but also may be seen after a surgery or infection elsewhere in the body. Of course an untreated cut or break in the skin near the elbow can also lead to an infection. An infection can cause other issues, namely inflammation, to manifest
Golfers elbow and tennis elbow are two common repetitive motion syndromes that occur in the elbows of adults. Pitchers elbow is another repetitive motion injury that usually only affects growing kids that take part in sports that require throwing, like baseball.
