|The condition known as de Quervain's tendonitis, or tenosynovitis, results from the tendons at the base of the thumb becoming irritated or inflamed. When the tendon gets inflamed, the tunnel that surrounds it swells, and it becomes painful to move the thumb or wrist. Those who suffer from de Quervain's tendonitis feel pain when they hold things or try to form a fist.|| |
|Causes of De Quervain's Tendonitis|
A change to the way the wrist normally works and moves because of a fracture, severe strain or overuse in the work place can also trigger de Quervain's tendonitis because of the new and unusual stress the tendons may incur.
|Signs & Symptoms|
The base of the thumb may become swollen and a cyst filled with fluid may even appear. The thumb, when moved, may sometimes catch or pop, and it may be hard to pinch. The nerve that lies on top of the tendon's sheath or tunnel may also become irritated and cause the index finger and back of the thumb to become numb.

|Non-Surgical & Surgical Treatments|
If the symptoms are very severe or the treatments tried so far don't work, surgery can often help. During the surgery, your hand surgeon will open up the compartment to give the inflamed tendons more room to move. This procedure eliminates the inflamed tendons swelling even further, which in turn increases the inflammation, and so on. Following the surgery, a splint may be suggested, but once comfort and strength have returned, normal hand, wrist, and thumb function will come back.
