Abstract

A system and method for fabricating a cosmetic cover for a prosthetic limb comprises the steps of: fitting and aligning a prosthetic limb to a wearer's residual limb; collecting orientational and positional data from adjustment points between the various endoskeletal and/or socket components of the residual limb; transmitting the orientational data to a CAD system that has access to the socket and endoskeletal component dimensions; using the CAD system to calculate inner surface dimensions for a cosmetic cover to be worn over the prosthetic limb according to the socket and endoskeletal component dimensions and according to the orientational and positional data; and downloading the inner surface dimensions from the CAD system to a CNC milling machine, which is adapted to carve the inner surface of a cosmetic cover from a carving blank using the calculated inner surface dimensions. Preferably, the system and method also includes the steps of gathering sound-side dimensions of the opposing sound limb and transmitting the sound side dimensions to the CAD system; using the CAD system to calculate outer surface dimensions for the cosmetic cover that is a 'mirror image' of the sound limb; and downloading the outer surface dimensions from the CAD system to the milling machine, which is adapted to carve the outer surface of the cosmetic cover from the carving blank using the outer surface dimensions. the data gathering and calculating steps are 4512 performed using the a digitizing tool integrated into the CAD tool.
