Abstract
A prosthesis for reconstructing a multibone joint such as a wrist. A patient's scaphoid is removed to create a void. The scaphoid has a plurality of adjacent bones, each of the adjacent bones comprising a surface generally facing the void. The surface of at least two of the adjacent bones is prepared by affixing a magnetic element thereto and a magnetic scaphoid implant is inserted into the void. A magnetic relationship exists between the magnetic elements and the magnetic scaphoid implant.
