Abstract:
An orthopedic protective assembly is disclosed. The orthopedic protective apparatus includes a foam shaped collar to conform to a user's neck area. The foam shaped collar comprises a multi-layer polymer material having a pliable outermost protective layer to absorb initial impact energy and additional layer(s). The additional layer(s) require(s) greater impact energy to deform than those of the pliable outermost protective layer. In one embodiment, shim extension(s) customize(s) impact energy absorption properties of the foam shaped collar by filling a gap between an underside of the foam shaped collar and a shoulder region of a user.
