The elbow is a hinge joint between the lower end of the humerus bone
in the upper arm and the upper end of the radius and ulnar bones in
the lower arm. The arm is bent and rotated at the elbow by the biceps
muscles in the upper arm. Ligaments located at the front, back, and
sides of the elbow help stabilize the joint.
Common elbow problems include:
Arthritis Common forms of arthritis that can affect the elbow include
osteoarthritis, rheumatoid arthritis, and infectious arthritis.

Bursitis Bursitis of the elbow, also called olecranon bursitis, occurs
as a result of injury or constant pressure on the elbow (for
example, when leaning on a hard surface). Learn more about bursitis.
Fractures Falling on an outstretched hand or directly on the tip of the
elbow can result in dislocation and/or several types of fractures,
depending on the fall. Learn more about fractures.
Injury Repetitive strain on the elbow can cause inflammation.
