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:
Common forms of arthritis that can affect the elbow include osteoarthritis, rheumatoid arthritis, and infectious arthritis. Learn more about arthritis.
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.
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.
Repetitive strain on the elbow can cause inflammation.
