Plain film radiographs revealed bilateral hip osteoarthritis with the presence of osteophytes, joint space narrowing, sclerosis, and cam-type femoroacetabular impingement (Figure 1).
The Intellijoint HIP  navigation camera (A) is enclosed in a
sterile drape and magnetically attaches to the pelvic platform (B). The
pelvic platform is installed on the ipsilateral iliac crest using two
pelvic screws (C). The tracker (D) is magnetically attached to the
femoral platform (E). The camera captures movements of the tracker and
relays the information to a workstation for review by the surgeon.

THA. While this device has received clearance from the FDA for use in primary and revision THA, it has not been evaluated for use in BHR. The posterior application of the navigation device was followed, which has been described in detail previously (Figure 2).
Post-operative radiograph: a 12-week, AP pelvis radiograph is depicted,
showing BHR that is well aligned with no evidence of loosening and no
femoral neck fracture. TraumaCad overlay (Brainlab, Chicago, IL, USA)
depicts post-operative cup position measured at 46  inclination and 17 
anteversion.

An antero-posterior (AP) pelvis x-ray of the right hip showed BHR that was well aligned with no evidence of loosening and no femoral neck fracture (Figure 3).
