Wrist tendonitis, also called tenosynovitis, is a common condition characterized by irritation and inflammation of the tendons around the wrist joint. Many tendons surround the wrist joint. Wrist tendonitis usually affect one of the tendons, but it may also involve two or more. Often wrist tendonitis occurs at points where the tendons cross each other or pass over a bony prominence.
The wrist tendons slide through smooth sheaths as they pass by the wrist joint. These tendon sheaths, called the tenosynovium, allow the tendons to glide smoothly in a low-friction manner.
When wrist tendonitis becomes a problem, the tendon sheath or tenosynovium, becomes thickened and constricts the gliding motion of the tendons. The inflammation also makes movements of the tendon painful and difficult.
