Introducing the

“The HipXpert is an ingenious tool thatdramatically reduces the chance of acetabular cup malpositioning compared to traditional methods of alignment. I have found it to be very simple and quick to use, in contrast to available computer-assisted methods.”

- Samuel S. Wellman, M.D.,Duke University Medical Center

Four Steps to Success

The HipXpert system provides a patient-specific solution using a mechanical navigation instrument and a software application with details of the surgical plan. The system takes minutes to use and provides accuracy equal to or better than high-end computer-assisted navigation5. Based on patented technology, the HipXpert is reusable, cost-effective, and easily deployed across multiple operating rooms. Simply put, it is the cup-alignment solution surgeons have been waiting for.

So simple, it’s brilliant.

“It gave me tremendous peace of mind knowing my surgeon was using the HipXpert. If your surgeon has it, your surgeon gets it.” - Mark Grant, Patient

The HipXpert vs. Alternative ApproachesThe HipXpert is the only acetabular cup positioning system available today that combines ease-of-use and cost-effectiveness with proven accuracy. When compared to other cup-alignment options, the choice is clear.

STUDY RESULTS: HipXpert More Accurate than CT-based NavigationIn a study comparing inclination and anteversion accuracy in 70 THAs performed using the HipXpert vs. a control group of 146 THAs performed using CT-based hip navigation, the HipXpert was statistically superior. Additionally, incision-to-dressing time using the HipSextant was 20 minutes faster than with the control group5. Following are the key results from the study.
