Prosthesis and method therefor

Abstract

Improved prosthetic components and a method for assembly therefor are described wherein the prosthesis comprises prefabricated modular components including a socket adapter, shank or pylon, a keel, and a foot. The method for preparation of the improved prosthesis reduces the time required for prosthesis preparation over that of the prior art, and includes the steps of making a cast of the remaining leg stump and forming a socket therefor; placing the socket in an alignment jig; assembling modular pieces including a prefabricated keel, pylon, and socket adapter; attaching the socket adapter to the socket; draping a final coating of copolymer on the prosthesis; and removing the pylon and socket adapter from the interior of the prosthesis.

What is claimed is:  
     
         1 . A method for constructing a prosthesis for placement on a remaining stump of a human limb, comprising the steps of: 
 making a cast of the remaining stump and forming a socket therefor;    selecting appropriate prefabricated modular components including at least a keel, a pylon, and a socket adapter;    assembling said prefabricated components;    adjusting a relative angle between said socket and said keel;    attaching said socket adapter to said socket;    draping a coating of copolymer over said assembled keel, pylon, socket adapter, and socket; and    removing substantially all of said pylon and socket adapter from an interior of said coating of copolymer.
