Abstract: A wrist support band for use in the treatment of wrist ailments. The wrist support band provides support to the wrist while at the same time allows mobility of the wrist. The wrist support band includes an elastic sleeve that contains a flexible mold support. The mold support incorporates two elongated protuberances and a central recess intermediate the protuberances. The sleeve is slid over the hand and wrist until the elongated protuberances are proximate the wrist's proximal carpal row. At least one strap is wrapped about the sleeve to hold the sleeve and mold support in position firmly against the wrist. The interior of the sleeve may also be equipped with an anti-slip patch to prevent the sleeve from sliding up and down the wrist or forearm.
