Method of implanting joint prosthesis with infinitely positionable head

A method for a surgical procedure, comprising:

• accessing an implanted joint prosthesis having an implant engaged within a bone of the joint and a first articulating component mounted by a first mating component to a first insert component removably mounted to the implant;
• partially disassembling the accessed implanted joint prosthesis by removing the first insert component with the first articulating component fixed thereto from the implant while the implant is engaged with the bone;
• determining an angular position of the first mating component with respect to the first insert component after partially disassembling the accessed implanted joint prosthesis using a replication instrument;
• replicating the determined angular position with a second insert component and a second mating component;
• fixing the second insert component and the second mating component at the replicated angle;
• mounting the fixed second insert component and second mating component to the implant engaged within the bone;
• and
• mounting a second articulating component to the second mating component.
