Product Description

The Best Thumb Spica Splint for De Quervain’s Tenosynovitis

The cock-up Wrist & Thumb Splint for De Quervain’s tenosynovitis (radial styloid tenosynovitis) is effective for easing pain associated with this condition because it is specifically designed for immobilization and protection. An ergonomic, aluminum metal stay accurately contours to your wrist for unbeatable support. However, it can be removed if you desire a sleeker, more flexible fit. Please note that the removable stay is very hard or rigid, not easily bendable because it is intended to be an immobilizing splint. If needed, you can slightly mold the thumb stay for customized thumb stabilization.

Treating a hand, thumb, or wrist injury may require some form of therapy or exercises meant to build strength and flexibility. Besides the obvious comfort aspect, free hand movement permitted by this wrist guard also means it can be used during physical therapy for an injury.

Tips to Help De Quervain’s Tenosynovitis Treatment Process:

If you are suffering from De Quervain’s tenosynovitis or a similar condition, treatment typically begins with following the steps of RICE — rest, ice, compress and elevate your hand, thumb, and wrist. These steps can reduce painful inflammation more quickly.

This brace for wrist and thumb injuries helps with both the rest and compression steps of this process. The orthopedic forearm splint with thumb abduction immobilizes the MP and CMC joint, helping with wrist pain on the thumb side by forcing these tendons to rest. The fastener straps of the thumb stabilizing wrist protector mean you can adjust the amount of compression it provides at both the wrist and thumb area. For additional compression, you might consider a bandage, glove, or wrist wrap.

As always, we strongly recommend speaking to a medical professional for a specific treatment plan tailored to fit your needs and injury.

What is De Quervain’s Tenosynovitis?

De Quervain’s tenosynovitis is a condition that affects the tendons on the thumb side of your wrist. It can be extremely painful and cause swelling. If you have this condition, it will probably cause pain when attempting to turn your wrist, grasp an object, or make a fist. Any activity that relies on repetitive hand or wrist movement can worsen the condition.

The exact cause of De Quervain’s disease is unknown, but risk factors include being a female between the age of 30 and 50, pregnancy, or jobs or hobbies that involve repetitive hand and wrist motions.

Causes of De Quervain’s Tenosynovitis:

  • Chronic overuse of your wrist
  • Repeating a particular motion day after day
  • Direct injury to your wrist or tendon; scar tissue can limit movement of the tendons
  • Inflammatory arthritis, such as rheumatoid arthritis

Symptoms of De Quervain’s Tenosynovitis:

  • Pain near the base of your thumb
  • A “sticking” or “stop-and-go” sensation in your thumb when moving
  • Difficulty moving your thumb or wrist when pinching or grasping
  • Swelling near the base of your thumb

Does This Wrist and Thumb Brace Help With Other Hand Injuries?

Yes, along with aiding De Quervain’s tenosynovitis, this thumb stabilizer is well equipped for easing pain associated with a number of thumb and wrist injuries, including:

The versatile design immobilizes the metacarpophalangeal (MP) joint and the carpometacarpal (CMC) saddle joint between your thumb and index finger in addition to supporting your wrist. This allows it to help with additional conditions, along with De Quervain’s tenosynovitis.

3 Reasons Why People Love Our Thumb Tendonitis Brace:

  1. New and Improved Design for Unbeatable Quality and Fit

    Based on some customer feedback, this product was updated and launched in March of 2019. We redesigned this De Quervain’s brace for a much more comfortable, secure fit. We also added new, medical-grade fastener, making it 10 times longer lasting than standard, over-the-counter braces you would be at Walgreen, CVS, or your local pharmacy.

  2. The Best Fit: Lightweight and Breathable

    The lightweight, breathable material and contour fit makes this comfortable wrist and thumb spica splint an excellent choice. Leaving your fingers free, it can be worn comfortably throughout the day and night for optimal healing. Contouring in the palmar area of this wrist and thumb support enables you to move your fingers normally, including grasping or clenching motions. There is also contouring at the fifth MP joint (pinky) of this wrist immobilizer, allowing you to spread your fingers.

  3. Removable Splints

    Two removable, aluminum splints immobilize your thumb and wrist in proper anatomical positioning, preventing re-injury and speeding up the recovery process. These aluminum splints can be removed if your treatment process requires something different.
