About

RI.HIP MODELER

This medical application assists surgeons in planning total hip arthroplasty by visualizing patient images and analyzing spinopelvic mobility. It helps determine optimal acetabular cup placement based on patient-specific data and implant specifications, aiming to reduce impingement.

Highlights
  • Total Hip Arthroplasty planning
  • Acetabular cup rotational selection
  • Spinopelvic mobility analysis
  • Patient-specific pelvic tilt determination
  • Simulation database integration
  • Impingement reduction recommendations
Read full description

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 characterise 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.

Verdict

The call

The clearest difference is update cadence: Implant Identifier at every 3 weeks against RI.HIP MODELER's every 9 months. Implant Identifier also leads on ratings volume (271 vs 1) and device support (3 vs 1). RI.HIP MODELER's advantage is monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.7). On price, ads and in-app purchases there is nothing between them.
