Damage to any of the structures that make up the elbow joint can cause elbow pain.
The elbow is a complex joint formed by the articulation of three bones – the humerus, radius, and ulna. Articular cartilage lines the articulating regions of the humerus, radius, and ulna. It is a thin, tough, flexible and slippery surface that acts as a shock absorber and cushion to reduce friction between the bones. The bones of the elbow are supported by ligaments, tendons, muscles, nerves and blood vessels.
Although the elbows are not weight-bearing joints, they are considered to be most important for the functioning of the upper limbs. Hence, even minor trauma or disease affecting the elbow may cause pain and limit the movements of the upper limbs. Arthritis is one of the common disease conditions affecting the elbow joint.
A biceps tear can be complete or partial. Partial biceps tendon tears will not completely break the tendon while complete tendon tears will break the tendon into two parts. Tears of the distal biceps tendon are usually complete and the muscle is separated from the bone. Tears of the distal biceps tendon most often result from a sudden injury or lifting a heavy object.
The arm in the human body is made up of three bones that join to form a hinge joint called the elbow. The upper arm bone or humerus connects from the shoulder to the elbow to form the top of the hinge joint. The lower arm or forearm consists of two bones, the radius, and the ulna. These bones connect the wrist to the elbow forming the bottom portion of the hinge joint.
