1. A method for preparing a patient'"'"'s hip for receiving an implant, comprising:
- providing a first orthopedic system comprising a reference post comprising an orientation sensor, an impactor coupled with the reference post, a first angle assessment guide, and a portable surgical orientation device attached to the angle assessment guide;
attaching the reference post to a hip bone of the patient;
measuring and recording a reference distance from the reference post to an anatomical landmark using the portable surgical orientation device;
removing the angle assessment guide, impactor, and portable surgical orientation device from the reference post;
providing a second orthopedic system comprising an alignment guide, a second angle assessment guide attached to the alignment guide, and the portable surgical orientation device attached to the alignment guide;
measuring an orientation of an anatomical plane using the second angle assessment guide;
orienting an implant relative to the anatomical plane and inserting the implant into the acetabulum using the second orthopedic system;
attaching a femoral broach to the patient'"'"'s femur, the femoral broach including a head;
positioning the head in the implant;
providing the first orthopedic system a second time; and
measuring changes in the reference distance.

14. A method for positioning a patient in a hip procedure, comprising:
-
advancing a reference device into a patient'"'"'s pelvic bone; coupling a surgical orientation device with the reference device such that the orientation device is not moveable relative to the pelvic bone; measuring at least one of the position or orientation of at least a portion of the patient'"'"'s hip joint using the surgical orientation device; and moving the patient'"'"'s hip joint to selected position the patient relative to a fixed reference frame based on the measurement on the surgical orientation device. - View Dependent Claims (15, 16, 17, 18)
