Distal Triceps Injuries
What is the distal triceps tendon?
The distal triceps tendon connects the triceps muscle (on the back of the upper arm) to the olecranon, the bony tip of the elbow. It allows you to straighten the elbow and push against resistance, such as during a push-up or overhead press.
A distal triceps tendon injury is a tear or rupture where the tendon attaches to the elbow. It can be partial or complete, and though relatively rare, it can lead to significant weakness and loss of elbow extension strength.
These injuries typically occur from a sudden forceful load to the elbow — such as trying to catch a fall or lifting something heavy. Direct trauma, overuse, steroid use, or certain medical conditions (e.g., chronic kidney disease) can also weaken the tendon.
Symptoms include pain, swelling, and bruising at the back of the elbow, along with weakness in extending the arm. A gap near the tendon attachment may be felt, and patients may have difficulty pushing or straightening the elbow.
Diagnosis is made through physical exam and testing elbow extension strength. X-rays may show a small bone fragment pulled off with the tendon. Ultrasound or MRI is often used to confirm the diagnosis and assess the extent of the tear.
Partial tears may be treated with rest, bracing, and physical therapy. Complete ruptures — especially in active individuals — typically require surgical repair to restore full arm strength and function.
Surgical repair involves reattaching the torn tendon to the olecranon bone using strong sutures and anchors or bone tunnels. This restores the tendon’s normal length and function, allowing the triceps muscle to extend the elbow effectively.
Recovery takes 4 to 6 months. Early healing involves immobilization or limited movement. Physical therapy gradually progresses from motion to strengthening. Most patients return to full activity, including lifting or sports, by 5 to 6 months after surgery.
