Abstract: A wrist/hand/finger orthosis comprises a pliable splint member elongated in a direction from forearm to fingertips, a cover enclosing the splint member, and a plurality of releasable straps connected to the cover. Proximal to distal, the splint member includes forearm, wrist, hand, and finger portions. A thumb peninsula extends from the hand portion of the splint member, and a circular cut out region is provided adjacent thereto for increasing pivotal freedom of the thumb peninsula. The straps have free ends which attach to respective attachment locations on the cover such that the straps cross over the patient's limb in diagonal or oblique orientation, and the strap attachment locations are preferably color-coded with the straps for ease of use.
