A minimally-thick orthopedic prosthesis is described which closely matches the end of a bone of a joint after that bone end has been minimally reshaped and resurfaced by an orbital or lineally oscillating orthopedic resurfacing tool in the minimally invasive orthopedic surgical repair or reconstruction of hip, knee, ankle, shoulder, elbow, wrist, and other joints. The original ligament tensions and the varus and valgus alignments of the joint are preserved and the marrow cavities of bones are not invaded avoiding the dangers of blood clots, heart attacks, and other complications.

A wrist prosthesis has first, second, and third components that in one form are a radial component, a metacarpal component, and a bearing component. The bearing component is non-fixed or non-stationary relative to one of the radial component and the metacarpal component when the wrist prosthesis is assembled such as when implanted into a patient. As such, in one form a rotational joint or union is provided on the radial component and the bearing component. The bearing component is thus free to rotationally ride on the radial component, preferably 360° thereabout. Distal the radial component, the bearing component includes an articulation surface. The metacarpal component includes an articulation surface that is complementary to the articulation surface of the bearing component. In this manner, the metacarpal component correspondingly moves relative to the bearing component. The bearing component is preferably made of a polymer such as polyethylene.

A wrist splint assembly for being custom-fitted to a hand and wrist to be supported. The wrist splint assembly includes a first splint for being positioned against and formed to the volar aspect of the hand and wrist, and a second splint for being positioned against and formed to the dorsal aspect of the hand and wrist. Each of the first and second splints defines a concave side edge extending inwardly toward the longitudinal axis of the splint for permitting ease of movement of the thumb and associated carpometacarpal joint of the hand against which the splint is positioned. Each splint also includes an inner cushion layer, an initially flexible intermediate layer overlying the inner cushion layer, and a flexible outer layer. The intermediate layer is a substrate impregnated with a moisture-curable resin that hardens upon curing to form a rigid structure of the substrate that retains a shape into which it is molded during curing for maintaining the flexible inner cushion layer in a conforming shape against the hand and wrist. A support retains the first and second splints in position on the hand and wrist during use of the splint assembly.

The forearm handle for the disabled is a device that allows a user to do many tasks with one arm that normally require two arms, such as raking, sweeping, or shoveling, while at the same time greatly reducing the stress placed on the wrist. The forearm handle is a frame that fits over either the right or left forearm of a user. The frame has two brackets extending along the sides of a user's forearm. At the elbow end of the frame the brackets are connected by a first pivoting U-shaped member. At the hand end of the frame the brackets are connected by a D-shaped handle having a grip and a socket. A second pivoting U-shaped member, an elastic strap, and a hook and loop fastener strap are further placed between the brackets to provide additional support. The socket on the D-shaped handle is adapted for the attachment of brooms, sporting accessories, a crutch, or the like.

Features for a prosthetic wrist and associated methods of rotation are described. The prosthetic wrist attaches to a prosthetic hand. Rotation of the prosthetic wrist is performed in combination with grip formation of the prosthetic hand. An IMU provides data associated with the orientation of the prosthetic hand. A desired grip for the prosthetic hand is selected, for example by gesture control. A rotation for the prosthetic wrist is determined based on the orientation of the prosthetic hand from the IMU data and on the selected desired grip. The prosthetic wrist techniques can also be used in combination with prosthetic arms, elbows and/or shoulders. Example structural configurations for the prosthetic wrist and hand are also provided.

A protective sports glove including a vent opening and an arched panel extending upward and over the vent opening. The glove can include a breathable material that extends across the vent opening to provide improved air flow to and from the interior of the glove. The arched panel can arch above the vent opening, and optional breathable material, so as to form a void under the panel, thereby providing impact protection to the wearer's hand while still enabling air to circulate through the vent opening to the wearer's hand. The arched panel can be configured to flex or bend when the hand is brought back toward the wearer's wrist or forearm, yet provide resistance to that backward movement to eliminate and/or reduce the overextension of the hand and wrist.
