Triceps Tendon Injuries

What is the Triceps Tendon?


The triceps tendon attaches the triceps muscle to the back of the elbow at the olecranon. It allows for straightening the arm.


What is This Condition?


  • Partial tears: small portion of tendon is damaged

  • Complete tears: tendon pulls fully away from the bone


What are the Symptoms?


  • Sudden pain in the back of the elbow

  • Swelling and bruising after injury

  • Weakness or inability to straighten the elbow against resistance

  • Sometimes a gap can be felt above the elbow


What Causes It?


  • Sudden forceful extension or fall on an outstretched arm

  • Direct trauma to the elbow

  • Risk factors: steroid use, chronic tendon irritation


How is It Diagnosed?


  • Exam: weakness with elbow extension, palpable gap

  • MRI or ultrasound: confirm extent of tear


How is It Treated?


Non-surgical:


  • For partial tears: rest, NSAIDs, and gradual physical therapy


Surgical:


  • Repair of the tendon back to the bone for complete tears or in cases of partial tears that have failed non-surgical treatment
