RI.HIP MODELER

RI.HIP is a non-invasive standalone Total Hip Arthroplasty (THA) planning software application designed to provide preoperative planning for hip implant acetabular cup rotational selection and placement. RI.HIP allows surgeons to visualize and perform analysis of digital images for assessment of spinopelvic mobility of the patient. The app is used to characterize patient conditions, manage patient performance expectations, and help surgeons determine acetabular cup placement based on spinopelvic mobility.
RI.HIP uses imported lateral sitting/standing X-rays to determine patient specific pelvic tilt. In addition to pelvic tilt, the algorithm considers typical patient activities and implants to enable a placement that is individually suited to the patient. The application accesses a simulation database which has been generated by the LifeMOD simulation platform. Hip kinematics and distance to impingement are calculated for each activity, given a set of implant specifications.
The software provides a baseline cup orientation recommendation intended to reduce incidences of impingement based on patient condition and implant specifications. The surgeon is reminded to verify and adjust the parameters based on their clinical judgment.

RI.HIP can be used preoperatively to plan implant placement using standing and sitting X-rays. Certain physiological characteristics may not be seen on a preoperative X-ray, but may be observed in the OR. The surgeon can change the plan intraoperatively upon viewing the hip joint characteristics.
