Abstract

An apparatus and method for providing an orthopaedic support having a flexible inner member and an exoskeleton that is molded directly onto the flexible inner member. One embodiment is a wrist support having a separate, attachable thumb spica, and may include a molded plastic exostructure supplying support for resisting motion of said wrist. An inner fabric support is attached to said molded exostructure for providing cushioning to the wrist area. Other embodiments include to said molded exostructure for providing an attachable stay; a web bridge that extends across and supports the web of the hand; an adjustable wrist support having an adjustable forearm portion that can accommodate various sizes of forearms; a wrist brace having a space to accommodate the web of the hand; and a support having an interior padding member, with the padding member itself having a support structure molded onto the padding.

Claims

1. A wrist support comprising:

a molded plastic exostructure main body arranged for supplying support for resisting motion of a wrist, the main body having a wrist portion, first and second opposed end portions extending from the wrist portion, and an arcuate web portion bridge connecting to the first and second side portions so as to extend across a web area between the thumb and forefinger of a wearer, the wrist portion, first and second opposed end portions and the web portion bridge continuously forming an inner periphery of a thumbhole for extension of a thumb therethrough, the web portion bridge forming an indentation; and

an overmold portion molded onto and formed over the web portion bridge so as to surround the indentation, such that the overmold portion is integrally and adjacently secured to the web portion bridge following a contour of the web portion bridge and being flush with contours of the first and second side portions, the overmold portion having a predetermined molded shape arranged not to become misshapen from use;

wherein the overmold portion is formed from a softer and more resilient material than the plastic material forming the exostructure such that the web bridge portion retains the shape of the web area while the overmold provide cushioning to the wearer when in use.
