What It Is

Triceps tendon tears are injuries to the triceps tendon at the back of the elbow. They are uncommon (Dunn et al., 2017). Most of the time the tendon pulls away from where it attaches to the bony tip of the elbow (the olecranon), usually when the muscle is working hard while the elbow is forced to bend, such as with a fall onto an outstretched hand or heavy lifting (Demirhan and Ersen, 2016). Weightlifters and people who use anabolic steroids or have had steroid injections near the tendon are among those reported to be at higher risk (Dunn et al., 2017).

Normal triceps tendons are firmly attached to the bone and are responsible for straightening the elbow. When the tendon tears away, the muscle cannot pull on the bone properly, which causes weakness and difficulty straightening the elbow. People often feel a pop, and a gap can sometimes be felt at the back of the elbow where the tendon normally is (Demirhan and Ersen, 2016). Sometimes, instead of the tendon tearing, the triceps pulls a small piece of bone off the tip of the elbow (AAOS, n.d.).

Tears can be partial (part of the tendon is torn) or complete (the tendon is fully torn away). Partial tears are often managed without surgery, while complete tears usually need surgical repair (Demirhan and Ersen, 2016).

Triceps Tendon Tear Anatomy

The triceps is one of the major muscles of the upper arm. It runs along the humerus, the main bone of the upper arm, between the elbow and the shoulder. The biceps bends the elbow and the triceps straightens it: whenever the triceps tightens, the forearm extends and the elbow straightens.

The triceps muscle has three heads (three parts of the muscle that start in different places) which join into one tendon that attaches to the olecranon. Tears almost always happen at this attachment at the elbow; tears higher up in the muscle are very rare (Demirhan and Ersen, 2016).
