The triceps tendon attaches the triceps muscle to the olecranon, the bony point of the elbow, and it is what straightens the elbow against resistance. A tear most often happens from a fall onto an outstretched hand or a sudden forceful load, like a missed bench-press lockout.
Triceps tendon ruptures are relatively uncommon, which is part of why they are sometimes missed. A complete tear leaves a gap and noticeable weakness with pushing, while partial tears may keep some strength. Distinguishing the two guides treatment.
Symptoms
Common findings include:
- Pain and swelling at the back of the elbow after a fall or forceful effort
- Weakness straightening the elbow, especially pushing or pressing
- A palpable gap or divot above the elbow in complete tears
- Bruising along the back of the arm
How it is diagnosed
The exam tests the ability to actively straighten the elbow against gravity and resistance. X-rays may show a small fleck of bone pulled off with the tendon, and MRI if needed can confirm whether the tear is partial or complete and how much tendon is involved.
The key decision is whether the tear is complete. A complete rupture loses meaningful pushing strength and, in active patients, is repaired surgically, ideally sooner rather than later, because a retracted tendon is harder to bring back.
Dr. Lee reattaches the tendon to the bone with a secure suture-anchor and transosseous construct that allows early, protected motion. Partial tears in lower-demand patients can often be managed without surgery, with bracing and a careful rehabilitation program.
Non-surgical treatment
Low-grade partial tears, particularly in lower-demand patients who retain good extension strength, can be treated with a period of bracing followed by progressive rehabilitation.
Surgical repair
Complete tears, and partial tears with meaningful weakness in active patients, are repaired by reattaching the tendon to the olecranon with a strong suture-anchor and transosseous construct. Secure fixation is what allows protected motion to start early and limits stiffness.
Recovery timeline
Recovery balances protecting the repair with restoring motion:
- Weeks 0 to 2Splint or hinged brace with the elbow relatively straight to protect the repair. Hand and shoulder motion encouraged.
- Weeks 2 to 6Progressive guided motion starts around week 4 in a brace, avoiding active straightening against resistance.
- Weeks 6 to 16Strengthening and a graded return to pushing, pressing, and sport as healing allows. Full strength can take 4-6 months of recovery.
What patients commonly misunderstand
Easy to underestimate:
- It is easy to underestimate. Because triceps ruptures are uncommon, they can be mistaken for a bruise or sprain. Persistent weakness straightening the elbow after an injury deserves an evaluation.
- Timing helps the repair. A complete tear repaired promptly is more straightforward than one addressed months later, after the tendon has retracted and scarred.
