Rigid splint supports the CMC joint and reduces the affects of thumb hyperextension. Useful for UCL injuries associated with ball sports, skiing and work related repetitive strain problems.
Wrap the velcro around the thumb and secure. Slide the thumb in the thumb portion of the support. Secure the wrist section with the shorter/wider velcro. Then wrap the thin velcro locking strap around the splint and secure. Splint can be removed when not required.
