Left and Right Hand Variants; Open-Palm Design; Adjustable Velcro Strap; Plate Reinforcement; Breathable Construction; and Free Size for Most Adults

Left Hand and Right Hand Variants — Select the Correct Hand Before Adding to Cart: This splint is available in Left Hand and Right Hand variants — please select the hand that corresponds to your affected thumb before ordering. The splint is shaped and positioned specifically for the thumb joint of the selected hand. If you need support for both thumbs, please order one of each variant. Ordering the wrong hand is the most common purchase error for thumb splints — double-check your selection before checkout.

Open-Palm Design — Full Hand and Finger Mobility During Wear: The open-palm construction leaves your palm and four fingers completely free — allowing you to type, grip, carry, and perform daily tasks without removing the splint. This makes it suitable for continuous daytime wear during work, activity, and recovery without sacrificing hand function. Compatible with keyboard use, mouse use, gripping tools, playing instruments, and most everyday hand activities.

Trigger Thumb Support — Stabilization for the Thumb Flexor Tendon: Trigger thumb (stenosing tenosynovitis) occurs when the thumb flexor tendon becomes inflamed and catches or locks when bending the thumb. This splint is designed to support the thumb in a stable, comfortable position that reduces the repetitive flexion and extension movements that can aggravate the tendon. Always consult your physician or physiotherapist for a diagnosis and treatment plan before using a splint for trigger thumb symptoms.

Thumb Arthritis and Tendonitis — Compression Support for Joint and Tendon Comfort: Thumb arthritis (including CMC/basal joint arthritis) and thumb tendonitis are the two most common diagnosed conditions driving thumb brace purchases. This splint provides targeted compression and mild stabilization at the thumb joint — designed to support a comfortable thumb position during daily use and activity that may help manage pain and discomfort associated with these conditions. Consult your healthcare provider before using a brace for diagnosed arthritis or tendonitis.

Sport, Gaming, and Instrument Use — Thumb Protection During Gripping Activities: Suitable for individuals who need thumb joint protection during activities that place repeated stress on the thumb — including sports with gripping (golf, tennis, climbing, skiing), video gaming (controller or mouse use), and playing musical instruments (guitar, piano, string instruments). The open-palm design is fully compatible with gripping, picking, and pressing hand movements. Protects the thumb joint without restricting the rest of the hand.

Adjustable Velcro Strap — Custom Compression for Your Thumb Size: The adjustable hook-and-loop Velcro strap allows you to set the exact compression level for your thumb joint — from light daytime support to firmer activity or recovery compression. Secure fit prevents the splint from shifting during wear. Easy to apply and remove with one hand. Free adjustable size accommodates most adult thumb sizes without requiring a specific size selection.

Please note: This product is sold as a single splint (1 piece), not a pair. If you need support for both thumbs, please order one Left Hand and one Right Hand.
