DeQuervain's tenosynovitis 

Introduction

DeQuervain's tenosynovitis was first described by a Swiss surgeon, Fritz de Quervain, in 1895. This condition  causes pain on the side of the wrist and forearm just above the thumb.  This is a common problem. This occurs when the thumb tendons (and the covering of the tendons called the synovium) become inflamed.

Causes

This condition arises when the  tendons are unable to glide through the tunnel smoothly and without friction.   Repetitive activities such as grasping, pinching, squeezing, or wringing may lead to a inflammation of the tendons and synovium (coverings around the tendons),  This can lead to swelling, which further prevents the smooth gliding action of the tendons within the tunnel. 

An injury to the tendons also makes it difficult for the tendons to slide easily through the tunnel.  Various forms of arthritis can also lead to this condition.

Symptoms

The first symptom is usually pain on the thumb side of the wrist.  The pain may spread up the forearm or down into the thumb.  The tendons may also "creak" when moving the thumb.  This is called crepitus.   There may be swelling along the line of the tendon.  Use of the hand and thumb becomes increasingly painful.
