Everything You Need to Know About First Dorsal Compartment Tenosynovitis

De Quervain’s Tenosynovitis causes the growth of painful muscles on the thumb side of the wrist. Muscles are rope-like structures that tendons to pull the bone. Patients can see them on their hand, elbow, neck, thigh, etc.

In De Quervain’s Tenosynovitis, also known as first dorsal compartment tenosynovitis, the muscles get narrow or take extra space in the tunnel. This is due to a hardening of the soft tissues that make up the tunnel or an increase in the soft tissue within the tunnel. In this condition, hand and thumb motion causes pain, especially with forceful grasping or twisting.

Causes

It is still not certain what causes De Quervain’s Tenosynovitis, but an alteration in the use of the hand can be a cause. In addition, monotonous movements, alteration in hormones, and swelling are some of the factors. When new mothers develop this condition, it typically appears 4 to 6 weeks after delivery.

Signs and symptoms

Patients with first dorsal compartment tenosynovitis usually experience the feeling of sharp or dull pain and swelling. This is either at the base of the thumb or the wrist. People of all ages can experience these problems.

Treatment

Treatments that relieve symptoms include:

·         A tape that stops you from moving your thumb and wrist

·         Tylenol or anti-inflammatory medications including Ibuprofen

·         Asteroid injection into the muscle compartment.

If these less painful options have provided relief, surgery to open the tunnel and make more muscle room can be considered. Discuss the best treatment option for you with your surgeon.
