Abstract
A method of performing an arthroplasty of a ball and socket joint with a surgical navigation system includes the step of digitizing landmarks to provide geometrical parameters of the joint and a limb depending there from, including digitizing aspects of a socket region of the ball and socket joint. A range of motion parameter is determined. A soft tissue tension parameter is determined. A functional goal is computed based on landmark data, the range of motion parameter, the soft tissue tension parameter, and a database of potential implants. An optimal socket position is solved for to minimize impingement of potential implants. An implant is chosen based on the optimal socket position and the functional goal. The joint is prepared to receive the chosen implant. The chosen implant is installed into the joint.
