ECU tendon, is one of the tendons that crosses the wrist, at the little finger side of it.
It can get injured in sports like Tennis, Golf and Rugby League. The injury may range from Tendinosis (wear) to Instability (tendon slipping out of the grove) to frank rupture.
The injury may be avoided by attention to proper technique, avoiding at-risk strokes and appropriate conditioning.
Treatment usually involves, rest and strengthening, sometimes injection and very occasionally surgery to stabilise or repair a tendon.
