The Tynor Thumb Spica Splint holds the thumb still in its natural, slightly open position and steadies the base of the thumb and the wrist. A trident-shaped aluminium stay slides into a pocket in the foam-padded body, and a wrist strap with a reverse buckle lets you set how firmly it holds. Your fingers are left free, so you can still use the hand for everyday tasks. One size fits either hand.

Key benefits
- A malleable, trident-shaped aluminium stay holds the thumb and its joints still at three points.
- A foam-padded, stitchless body with a thumb loop is soft on the skin and easy to put on yourself.
- A reverse-buckle wrist strap gives adjustable compression and a secure, snug hold at the wrist.
- Fits the left or right hand and leaves the fingers free for daily tasks.
Features
- Aluminium splint: A rigid but malleable stay shaped like a trident gives three-point support and keeps the IP, MCP and CMC joints of the thumb steady.
- Splint pocket: The stay sits in its own pocket so it does not shift as you move, and it can be slid out.
- Foam-padded body: Laminated fabric lined with PU foam cushions the hand and wrist for comfortable longer wear.
- Stitchless design and thumb loop: A smooth inner surface with no seams to rub, and a thumb loop that makes the splint easy to wear on your own.
- Reverse-buckle wrist strap: The strap pulls back on itself for controlled compression and a firm grip around the wrist.
- Ambidextrous: The same splint suits either hand.
