Apparel worn for the aid and protection of the body and for the support and assistance of impaired joint function

A protective orthopedic prosthetic device comprises:

• a means for attaching the device to the limb or body of the wearer,
• a base member being generally flat having an attaching end which attaches or is inserted into the means for attaching the device to the body of the wearer, and the base member having a convex semi-circular end whose edge has a T-shaped groove,
• a plurality identical of crescent shaped discs having a convex edge whose cross-section is a T-shaped groove identical to the T-shaped groove of the base member, and each crescent shaped disc having a concave edge whose cross section is a T-shaped tongue which is sized to slideably fit the T-shaped groove of the base member and other crescent shaped discs;
• the concave edge and the convex edge of the crescent shaped discs being circular arcs whose radii are both approximately equal to the radius of the semi-circular end of the base member;
• and an end piece being generally flat having an attaching end which attaches or is inserted into the means for attaching the device to the limb or body of the wearer, and having a concave semi-circular end whose cross section is a T-shaped tongue which is sized to slideably mate and fit the T-shaped groove in the crescent shaped disc and the T-shaped groove in the base member, the radius of the concave semi-circular end of the end piece being approximately equal to the radius of the semi-circular end of the base member,
• and a plurality of stop blocks, being two for each T-shaped groove, each step-block having a threaded tap at its approximate center said threaded tap passing clear through the stop-block, the stop-block being sized to loosely slideably fit the T-shaped groove in the base member and crescent shaped discs,
• and a plurality of threaded set screws to screw into and through the threaded taps,
• and an optional means for aiding joint dysfunction.
