De Quervain's Tenosynovectomy

De Quervain's tenosynovectomy is a surgical procedure used to treat De Quervain's tenosynovitis, a condition that affects the tendons on the thumb side of the wrist.

What is De Quervain's Tenosynovitis?

De Quervain's tenosynovitis is a condition characterized by inflammation of the tendon sheath that surrounds the tendons of the extensor pollicis brevis and abductor pollicis longus muscles. These tendons are responsible for thumb movement, including extension and abduction.

Symptoms

The symptoms of De Quervain's tenosynovitis include:

• Pain or tenderness on the thumb side of the wrist
• Swelling in the affected area
• Crepitus (grinding sensation) when moving the thumb
• Limited thumb movement due to pain

Causes and Risk Factors

The exact cause of De Quervain's tenosynovitis is often unknown, but it can be related to:

• Overuse or repetitive strain on the wrist and thumb
• Direct injury to the tendon or wrist
• Rheumatoid arthritis or other inflammatory conditions

The Procedure: De Quervain's Tenosynovectomy

De Quervain's tenosynovectomy is a surgical procedure that involves:

• Making an incision on the thumb side of the wrist to access the affected tendon sheath
• Releasing or removing the inflamed tendon sheath to relieve pressure and reduce inflammation
• Potentially repairing any damaged tendons or surrounding tissue
• Closing the incision site with sutures or staples

Post-Operative Care and Recovery

After the procedure, patients typically undergo a period of recovery that includes:

• Pain management with medication
• Immobilization of the wrist and thumb in a splint or cast for several weeks
• Physical therapy to regain strength and range of motion in the thumb and wrist
• A gradual return to normal activities, avoiding heavy lifting or repetitive strain on the wrist and thumb

Complications and Risks

As with any surgical procedure, De Quervain's tenosynovectomy carries potential risks and complications, including:

• Infection at the incision site
• Nerve damage or numbness in the thumb or wrist
• Tendon rupture or re-injury
• Chronic pain or stiffness in the wrist and thumb

Success Rate and Outcome

The success rate of De Quervain's tenosynovectomy varies depending on individual factors, such as the severity of the condition and overall health. Generally, the procedure can provide significant relief from symptoms and improve function in the thumb and wrist.
