Biceps Tendon Rupture with Distal Retraction: Definition & Understanding

Definition

A full-thickness rupture of the biceps tendon with distal retraction is a tear of the tendon that connects the biceps muscle to the forearm bone (radius). The tendon is completely torn through, and the muscle retracts (pulls away) from the bone.

Anatomy

The biceps brachii muscle is located in the front of the upper arm. It has two tendons, one that attaches to the shoulder joint and one that attaches to the radius bone in the forearm. The distal biceps tendon is the tendon that attaches to the radius bone.

Causes

A full-thickness rupture of the distal biceps tendon is usually caused by a sudden, forceful contraction of the biceps muscle. This can occur during activities such as weightlifting, throwing, or playing sports. The tendon can also be ruptured by a direct blow to the elbow.

Symptoms

The symptoms of a full-thickness rupture of the biceps tendon include:

* Pain in the front of the elbow

* Swelling and bruising around the elbow

* Weakness in the arm and forearm

* Difficulty rotating the forearm

* A visible deformity in the elbow

Treatment

Treatment for a full-thickness rupture of the distal biceps tendon typically involves surgery to reattach the tendon to the bone. Surgery is usually performed arthroscopically, which means that it is done through small incisions using a camera.

After surgery, the arm will need to be immobilized in a cast or sling for a period of time. Physical therapy will be necessary to help restore range of motion and strength to the arm.

Prognosis

The prognosis for a full-thickness rupture of the biceps tendon is generally good. Most people are able to return to their normal activities within a few months of surgery.
