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
Claims27
A method of reconstructing a joint, comprising:
- removing a bone comprising part of a multi-bone joint to be reconstructed to create a void, hones 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 at least two 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.
A prosthesis comprising:
- a magnetic implant approximating the size of a bone to be replaced;
- a first magnetic bone implant securable to a first bone adjacent the bone to be replaced;
- and
- a second magnetic hone implant securable to a second bone adjacent the one to be replaced,
- wherein each of the first and second magnetic bone implants have a magnetic relationship with the magnetic implant.
A method of repairing an injured multi-bone joint, the joint including a plurality of bones, interfaces between the bones, at least one of those interfaces being damaged, and ligament connections at the interfaces, the method comprising:
- removing at least one bone having an injured interface, but less than all of the bones, and all of the ligaments attached to the removed bone;
- replacing the removed hone;
- and
- replacing the ligaments with a magnetic connection.
