Tendon Rupture

Tendon Rupture: Causes, Symptoms, Treatment, and Prevention

A tendon rupture is a complete tear of a tendon—the strong band of tissue that connects muscle to bone. These injuries can happen suddenly, often during physical activity, or may occur spontaneously in weakened tendons without a clear injury. Common rupture sites include the shoulder, elbow, knee, ankle, and hand.

Some tendon ruptures involve flexor tendons, which help bend a joint, or extensor tendons, which straighten a joint. These are especially common in the hand, wrist, and foot. Spontaneous tendon ruptures may occur in people with chronic tendon irritation, steroid use, or certain medical conditions that affect connective tissue health.

Symptoms include a sudden snap or popping sensation, sharp pain, swelling, bruising, and difficulty moving the affected joint. In some cases, the tendon may visibly recoil or create a noticeable gap under the skin.

Diagnosis is made through a physical exam and often confirmed with imaging such as ultrasound or MRI to assess the extent of the tear. Early diagnosis is important to preserve function and prevent long-term weakness.

Treatment depends on the location and severity of the rupture. Partial tears may be managed with splinting, rest, and physical therapy. Complete ruptures often require surgical repair to reconnect the tendon and restore movement. After treatment, rehabilitation is important to rebuild strength and flexibility.
