Extensor carpi ulnaris tendinopathy
Extensor carpi ulnaris tendinitis
In the case of this tendinopathy, the tendon of the muscle called the "extensor carpi ulnaris" is affected. Often the tendon is inflamed through overuse. The symptoms are located on the top of the wrist, at the base of the little finger.
The tendon of the extensor carpi ulnaris runs along a bony nodule (the ulnar styloid process) located on the top of the wrist. This is the site where the pain is generally felt.
Description of the condition
Cause and origin
The symptoms usually occur gradually as a result of overuse. Extensor carpi ulnaris tendinopathy is common in tennis players (racket sport players), baseball players, golfers and rowers.
Signs & symptoms
- Pain on the top and pinky-side of the wrist.
- Swelling (of the tendon) sometimes occurs.
- Pain when extending the wrist against resistance, particularly if the wrist is simultaneously bent towards the little finger (ulnar deviation).
- The tendon may be sensitive if pressed on.
