The development of the formfit thumb spica has greatly assisted many individuals suffering from wrist and thumb pain in the recovery after an injury. Most designs are customizable in their available levels of padding, and it's this effect that creates a comfortable, yet still sturdy ability, ultimately allowing recovery and healing to take place. This kind of thumb spica is often used after a cast has been removed from the arm, because it allows the very beginnings of movement, allowing the tendons and muscles to start redeveloping after atrophy, but still restrains from too much movement that could be bad.
