Tendon Injury or overuse
Distal Biceps RuptureDistal biceps ruptures happen most commonly in men as a result of eccentric load. The biceps is responsible for supination (turning the palm of the hand up) strength, but very little flexion strength. If treated nonoperatively, supination strength and cosmesis will be the greatest effects. We live in a right handed world and most activities done with the right hand require supination (screw drivers, door handles, etc.)

Distal Triceps RuptureThese are also the result of eccentric extension loads. Small partial tears can be managed nonoperatively. If there is significant loss of strength or disruption of extensor mechanism, this should be treated operatively.

Tennis Elbow and Extensor RuptureTennis elbow is actually a degenerative tendon disease, not an inflammatory disease. This and partial ruptures of the extensors are treated with physical therapy. Very few tennis elbows actually require surgery with epicondylar debridement. Complete extensor ruptures will require repair if weakness and pain are significant.

Golfer's elbow and Flexor pronator RuptureThis is also a degenerative entity, most often responsive to physical therapy
