Abstract: System, including methods and apparatus, for replacing an end of a bone, such as a radial bone, with a prosthesis. In exemplary embodiments, the prosthesis is a radial head prosthesis having a stem portion and a head portion. The head portion may be configured to be (a) placed onto the stem portion by movement of the head and stem portions relative to one another transverse to a longitudinal axis of the stem portion, and then (b) rotated with respect to the stem portion to produce friction that firmly attaches the head portion to the stem portion.

Abstract: An operating room connector is used in conjunction with a multiple electrode SCS system which can easily detach and connect to an external trial stimulator (ETS). By connecting the electrode SCS system to a stylet handle, and then locking the stylet handle within a slot of the connector platform, a user is able to minimize the required steps in connecting the ETS to the implanted SCS lead system. The ETS can then be used to readjust the position of the electrode array(s) previously implanted to deliver an optimal stimulation therapy.
