Claim 0:
1. A system for performing a hip joint replacement, comprising:
an orientation sensing device, wherein the orientation sensing device comprises at least one inertial sensor, wherein the at least one inertial sensor is sensitive to the direction of gravity;
two pins configured to be driven into the pelvis in a spaced apart configuration;
a support platform configured to receive the two pins to couple the support platform to the patient positioned relative to a surgical table, the patient having a hip joint comprising an acetabulum and a femoral head, wherein the support platform comprises a locking device for securing the platform to the pins,
wherein the orientation sensing device is configured to couple to the support platform, wherein, in use, an orientation of the inertial sensor is recorded as an indication of the orientation of a reference frame comprising a first plane and a second plane when the orientation sensing device is coupled to the support platform coupled to the patient;
an impactor docking device, wherein the orientation sensing device is configured to be decoupled from the support platform coupled to the patient and then coupled to the impactor docking device,
wherein the orientation sensing device provides an indication of the orientation of an impactor relative to the reference frame comprising the first plane and the second plane based upon an orientation of the inertial sensor of the orientation sensing device when the orientation sensing device is coupled to the impactor docking device, wherein the support platform is configured to remain coupled to the patient while the orientation sensing device is coupled to the impactor device and provides the indication of the orientation of the impactor.
