Abstract
A method is provided for implanting a joint prosthesis for a damaged joint, wherein the steps include removing the damaged joint and initially anchoring two stem members into adjacent bones and inserting a temporary occupier at the joint location between the two stem members. The occupier is configured to allow only limited movement of the bones having the stem members. After the area around the occupier has healed, the occupier is removed and a specially configured ball and socket is installed as the joint to allow for incremental adjustments of the ball and socket relative to the two stem members during the installation procedure to simulate the natural bending motion of the joint once healed.
