De Quervain's Disease

De Quervain's disease, also known as De Quervain's tenosynovitis, is a condition that affects the tendons on the thumb side of your wrist. It occurs when the tendons around the base of the thumb are irritated or constricted.

What is De Quervain's Disease?

De Quervain's disease is a type of repetitive strain injury that affects the tendons and synovium (the membrane surrounding the tendon) of the abductor pollicis longus and extensor pollicis brevis muscles. These muscles are responsible for thumb movement, including extension and abduction.

Symptoms of De Quervain's Disease

The symptoms of De Quervain's disease may include:

• Pain or tenderness on the thumb side of the wrist
• Swelling on the thumb side of the wrist
• Difficulty moving the thumb, especially when forming a fist or grasping objects
• A "catching" or "snapping" sensation when moving the thumb
• Pain that radiates up the forearm
• Weakened grip strength

Causes of De Quervain's Disease

De Quervain's disease is often caused by repetitive movements or activities that involve the thumb, such as:

• Typing or using a computer mouse
• Gardening or using pruning shears
• Playing musical instruments, especially those that require repetitive thumb movements
• Lifting or carrying heavy objects
• Sports that involve throwing or catching, such as baseball or tennis

Treatments for De Quervain's Disease

Treatment for De Quervain's disease typically involves a combination of the following:

• Rest and ice: Avoiding activities that aggravate the condition and applying ice to reduce pain and inflammation
• Physical therapy: Stretching and strengthening exercises to improve thumb mobility and reduce pain
• Bracing or splinting: Using a wrist splint or brace to support the wrist and thumb, especially during activities that exacerbate the condition
• Pain relief medications: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, to reduce pain and inflammation
• Corticosteroid injections: Injecting corticosteroids into the affected tendon to reduce inflammation and relieve pain
• Surgery: In severe cases, surgery may be necessary to release the constricted tendon and relieve pressure on the nerve

Prevention of De Quervain's Disease

To prevent De Quervain's disease, it is essential to:

• Avoid repetitive movements or activities that involve the thumb
• Take regular breaks to stretch and rest the hands and wrists
• Use proper technique when performing activities that involve the thumb
• Wear a wrist splint or brace during activities that exacerbate the condition
• Maintain good overall health, including a healthy weight and regular exercise
