Abstract
A prosthetic joint for replacement of bone joints having a one-piece body of flexible physiologically inert material. The body has an enlarged central portion with two stem portions extending oppositely from the central portion for insertion into the medullary canal of bone. The central portion of the body has a height equal to or greater than its width and a slot extending substantially through the enlarged central portion from the distal end of the dorsal surface of the central portion toward the proximal end of the volar surface of the central portion forming a hinge at the volar surface. The hinge is offset from the center of said central portion toward the proximal end of the central portion.
