AS-303 Wrist Brace with Thumb Splint
A medical brace designed to stabilize the thumb and support the wrist. The AS-303 limits unwanted thumb motion using an internal aluminum stay, while its design supports the wrist. The perforated Neoprene/Airprene construction promotes breathability, and the adjustable closure helps achieve a secure, comfortable fit.
Key features
- Thumb motion restriction to help stabilize thumb joints.
- Wrist support in the same brace for combined stabilization.
- Integrated aluminum splint for firm support.
- Perforated Neoprene/Airprene material for ventilation.
- Adjustable fit around the wrist.
Intended use
For supporting and limiting movement of the thumb and wrist in cases where reduced mobility is recommended by a clinician.
- Selected ligament injuries and sprains.
- Thumb or wrist overuse and joint strain.
- Protection during recovery when motion reduction is advised.
Not a substitute for medical diagnosis. AS-303 is primarily designed to stabilize the thumb and wrist; for conditions such as carpal tunnel syndrome, a clinician should determine the appropriate brace type.
Sizing and selection
Measure wrist circumference and select the size accordingly:
- S/M: 13–17 cm
- L/XL: 17–21 cm
- XXL: 21–23 cm
Choose the size that matches the measurement. Hand orientation (right/left) depends on the version supplied; verify orientation before use.
