A triceps tendon rupture occurs when the tendon connecting the arm bone to the triceps tears. Patients suffering from this rare but serious condition often experience pain and an inability to straighten the elbow. While partial tears of the triceps tendon can often be treated non-surgically, patients suffering from a complete tendon rupture will likely require surgery to repair the tendon and resume normal arm function. A board certified orthopedic surgeon, Dr. Eric Millstein specializes in sports medicine procedures like surgery to repair a triceps tendon rupture.
