OTC 2387 Thumb Spica Wrist Brace | 8" Maximum Support Wrist & Thumb Splint

The OTC 2387 is designed to provide maximum support for the wrist and thumb. It is commonly used for thumb and wrist stiffness from repetitive use, thumb sprains and ligament strains, wrist and thumb joint instability, repetitive-use discomfort, wrist sprains, post-cast recovery, and post-procedure recovery support.

A thumb spica brace is a type of support that immobilizes both the wrist and the thumb together. The term "spica" refers to the figure-eight wrapping pattern that stabilizes the thumb joint while keeping the wrist in a neutral position.

Yes. The OTC 2387 is available for both the left and right hand. Please select the correct hand when ordering to ensure proper thumb and wrist alignment.

Measure the circumference around your wrist. Match your measurement to the sizing chart: X-Small (4.5–5.5 in), Small (5.5–6.5 in), Medium (6.5–7.5 in), Large (7.5–8.5 in), X-Large (8.5–10 in).

Yes. The ergonomic palmar crease design allows full finger dexterity, so you can type, write, and perform most daily tasks while wearing the brace. Only the thumb and wrist are immobilized.

Yes. The OTC 2387 features removable palmar and radial thumb splints, allowing you to customize the level of support based on your needs and comfort, or to remove them for washing.

Yes. By maintaining the wrist in a neutral position, the OTC 2387 helps reduce strain on the wrist and thumb tendons during repetitive activities like typing, gripping, and lifting — making it a popular choice for office workers, tradespeople, and athletes.

Yes. The breathable open-cell urethane foam and soft Lycra® lining make it comfortable for extended all-day wear. Its lightweight, low-profile construction also allows it to fit under clothing.

Yes. The OTC 2387 can be worn at night, particularly for repetitive-use wrist and thumb discomfort, where nighttime immobilization helps reduce morning stiffness.

Yes. The OTC 2387 is made from latex-free materials, making it safe for individuals with latex sensitivities.

Remove the splints before washing. Hand wash the brace with mild soap and warm water, rinse thoroughly, and air dry. Do not machine wash, tumble dry, bleach, or iron, as this may damage the foam and Lycra® lining.

The OTC 2387 can be used during post-procedure recovery for maximum wrist and thumb support. Always follow your care provider's specific recommendations regarding brace use after a procedure.

Yes. The thumb spica design stabilizes the basal thumb joint (CMC joint), a common area of discomfort and stiffness. Immobilizing this joint reduces strain during daily activities.

The brace should feel firmly supportive without restricting blood flow. You should be able to slide one finger under the straps. If you experience numbness, tingling, or increased swelling, loosen the straps or try a larger size.

It is suitable for low-impact activities such as golf, tennis, and pickleball where wrist and thumb support is needed. For high-impact or contact sports, consult your care provider to determine if this brace is appropriate.

No prescription is required. The OTC 2387 is an over-the-counter brace available directly from Must online or at our showroom.

Unlike a standard wrist brace that only supports the wrist, the OTC 2387 also immobilizes the thumb through its spica design and removable thumb splint. This makes it specifically suited for thumb concerns like repetitive-use strain and thumb ligament injuries.

Wear time depends on your situation and your care provider's guidance. Many users wear it throughout the day during activity and remove it during rest. Consult your care professional for personalized guidance.
