Overview
The distal triceps tendon attaches the triceps to the olecranon. Repeated pressing can gradually irritate it; a fall onto an outstretched hand or a forceful contraction can cause a partial or complete tear.
Gradual Tendon Pain
Tendinopathy usually causes localized pain just above the point of the elbow during pressing, dips, push-ups or resisted elbow extension. Initial care commonly reduces the most irritating volume, then rebuilds extension strength gradually.
Signs More Concerning for a Tear
- Sudden pop at the back of the elbow
- Rapid swelling or bruising
- A palpable gap above the olecranon
- Marked weakness or inability to straighten the elbow against gravity
Pain alone cannot determine tear size. Ultrasound or MRI may be used when examination suggests a significant injury.
Treatment
Most gradual tendinopathy and some partial tears are initially managed with activity modification and structured rehabilitation. Complete tears, major strength loss and selected partial tears may need surgical consultation.
When to Get It Assessed
Seek prompt assessment after an acute injury with a pop, gap, bruising or major pushing weakness. Red, hot swelling directly over the elbow may instead indicate olecranon bursitis, including possible infection.
