Dynamic planning for THA

Summary

MyHip aims at creating a complete solution for the planning and execution of total hip arthroplasty (THA). By considering preoperatively the kinematics of the prosthetic hip and pelvis tilting, accurately modeled from the patient morphology, a dynamic planning for THA can be defined. This novel planning provides operating parameters which aim to minimize the onset of articular conflicts and (sub-)luxations. Furthermore, the creation of intra-operative guidance tools for the faithful reproduction of the surgical planning strengthens this dynamic planning for THA.

In this project, Artanim was responsible for the development of the dynamic simulation module of the prosthetic hip driven by motion capture data.

Summary

Many patients wonder about the risks related to sexual activity after total hip arthroplasty (THA), but this issue remains rarely discussed between patients and surgeons. To date, the relative risk of prosthetic or bony impingement and joint instability during sexual activities after THA is unknown. Hip range of motion necessary to perform sexual positions has also never been quantified.

The goal of this study was to obtain realistic motion data for 12 common sexual positions and to evaluate relative risk of impingement and joint instability during their practice. We therefore conducted an in-vivo study with two volunteers using motion capture and magnetic resonance imaging. The data obtained were then used for computer simulations of prosthetic hip joint 3D models. Our aim was to provide surgeon or other healthcare professionals with scientifically validated information, as well as specific instructions to answer patient’s inquiries.
