1. A hip procedure navigation system, comprising:
a first pin configured to be driven into a pelvic bone of a patient,
a second pin configured to be driven into the pelvic bone of the patient,
a fixation base comprising a first channel configured to receive the first pin and a second channel configured to receive the second pin, wherein the fixation base is configured to slide along the first pin received within the first channel and the second pin received within the second channel,
a threaded fixation device configured to be rotated to secure the fixation base to the first pin and the second pin, wherein the first channel and the second channel extend in a direction traverse to the direction of the threaded fixation device,
a navigation device configured to be removably coupled to the fixation base, wherein the navigation device comprises at least one inertial sensor,
wherein the at least one inertial sensor is configured to determine cup inclination and anteversion angles, wherein a display provides an indication of the cup inclination and anteversion angles.
