Abstract: The present invention relates to an othosis or splint which can contain multiple features. All splints contain a moldable thermoplastic insert surrounded by padding material. The insert has slits between the digits of the hand so that the insert can be molded for the individual digits. This padded splint goes underneath the hand, wrist, and forearm. A separate moldable thermoplastic insert, again surrounded by padding can form a dorsal portion to go opposite the splint on the back of the hand, wrist, and forearm creating a “bi-valve” type of splint to address wrist hyperextension, extensor tone or other needs to control this area of the extremity. A plurality of straps attach to the padding of the underneath splint. Cylindrical shaped rolls can be attached to the insert of the splint just proximal to a patient's hyperextended joint(s).
