Claim:
1. An intraoperative system for rotating a misrotated prosthetic cup inserted into a pelvic bone of a patient to within a first predetermined threshold of a desired rotation relative to a reference frame of the pelvic bone, the system using a rotation determining system establishing an intraoperative rotation of the misrotated prosthetic cup, comprising: a rotating device including a set of actuators, said set of actuators having one or more actuators, said positioning device responsive to the intraoperative rotation to identify a group of actuators from said set of actuators, said group of actuators including at least one actuator configured to predictably rotate the prosthetic cup within the pelvic bone without translation responsive to a strike coupled to a peripheral rim of the prosthetic cup by said group of actuators, said rotating device further including a selector activating said group of actuators and configured to initiate said strike at a location on said peripheral rim of the prosthetic cup predetermined to rotate the prosthetic cup within the reference frame by predefined relative rotation amounts of abduction and anteversion.
