Fig. (1) The Intellijoint HIP surgical smart tool in use. The camera (A) is magnetically attached to a pelvic platform (B) fixed to the iliac crest. The camera captures movements of the tracker (C), magnetically attached to a femoral platform fixed to the greater trochanter. Data is transferred in real-time to a workstation placed outside of the sterile field. The system is self-contained and portable, requiring no system-specific installation of equipment in the OR.
