General Information
The de Quervain's wrist splint is a medical device designed to provide support and stabilization to the wrist area, particularly the extensor pollicis brevis and abductor pollicis longus tendons. It is commonly used to treat de Quervain's tenosynovitis, which is a condition where these tendons become inflamed and result in pain and swelling in the wrist.

Medical Definition
de Quervain's tenosynovitis is an inflammation of the sheath that surrounds the tendons of the extensor pollicis brevis and abductor pollicis longus in the hand. The cause of this inflammation is often repeated or excessive hand movements, such as opening a jar or turning a door handle.

Causes
Repetitive movements of the wrist and thumb, especially combined movements with ulnar deviation and thumb flexion or extension, can lead to microtears in the tendons' covering and the development of fibrosis, which can cause pain and stiffness.

Symptoms
The main symptoms of de Quervain's tenosynovitis include pain on the lateral aspect of the wrist, particularly at the base of the thumb, and tenderness over the tendons. There may also be swelling and a feeling of the thumb "getting stuck" in motion.

Diagnosis
Diagnosis can be made through a physical examination and may include ultrasonography or MRI to confirm the presence of tenosynovitis and assess the severity of the injury.

Treatment
Treatment typically involves the use of a wrist splint to provide support and stabilization. This splint is usually worn for a short period of time, until symptoms resolve. Additionally, physical therapy, rest, and pain relief measures are often prescribed.

Prevention
Prevention of de Quervain's tenosynovitis includes avoiding repetitive or excessive movements of the wrist and thumb, using ergonomic techniques when holding objects, and wearing appropriate shoes that support the wrist.

Cost
The cost of a de Quervain's wrist splint can vary widely depending on the brand, quality, and features. In China, prices can range from around 20 yuan for a basic model to几百甚至上千元不等 for more advanced or high-end splints.

Reviews and Comparison
According to reviews and comparisons, there are several brands of de Quervain's wrist splints available on the market. Most manufacturers offer multiple styles and variations to cater to different user needs. Users generally appreciate the convenience and instant relief that a good wrist splint can provide.
