The elbow is a complex joint of the upper limb formed by the articulation of the long bone of the upper arm or humerus and the two bones of the forearm, namely, radius and ulna. It is one of the more important joints of upper limb and is involved in basic movements such as flexion and extension of the upper limb and rotation of the forearm.
The elbow joint is supported by the ulnar collateral ligament, radial collateral ligament and the annular ligament. These ligaments provide stability and strength to the elbow joint.
The elbow joint also has the attachment of the common flexor and common extensor tendons. These groups of muscles assist in rotational movement of forearm as well as the movements of the wrist and hand.
Injuries to the elbow joint do not necessarily have to be dislocations or fractures. The complex structure of tendons and ligaments that hold your bones together and attach to the muscles are crucial to elbow joint function. Injuries to the ligaments and tendons can occur with overuse or repetitive stress on the elbow joint.
