Abstract
A method of reconstructing a wrist includes removing a patient's scaphoid 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.

A method of reconstructing a wrist joint, comprising:
- removing a bone comprising part of a multi-bone joint to be reconstructed to create a void, bones in the multi-bone joint comprises cooperating surfaces and connecting ligaments, the removed bone having a plurality of adjacent bones, each of the adjacent bones comprising a surface generally facing the void;
- replacing the surfaces of the adjacent bones with a magnetic element;
- and
- inserting a magnetic implant into the void,
- wherein at least one of the magnetic implant and the magnetic element includes a magnet;
- wherein the removed bone is the scaphoid and wherein the at least two adjacent bones having surfaces replaced with a magnetic element are selected from the trapezium, the trapezoid, the lunate, the capitate and the radius.
