  • a guide for a hip joint surface of a patient, the guide configured to engage the hip joint surface of the joint and having a guiding element oriented along an alignment axis;

    a guiding tool having a shaft couplable to the guiding element of the guide such that the shaft of the guiding tool is oriented along the alignment axis; and

    a three-dimensional orientation device having a transparent outer surface and an inner bubble viewable through the outer surface, the orientation device removably couplable to the shaft of the guiding tool and intra-operatively calibrated by marking with a mark on the outer surface a position of the bubble to indicate an orientation of the alignment axis, such that, after calibration, the orientation device can be removably coupled to a shaft of a surgical instrument to align the shaft along the alignment axis by changing the orientation of the shaft of the surgical instrument to center the bubble around the mark.
