Suivi des structures osseuses par échographie : application à l'arthroplastie totale de la hanche

Abstract : The principal aim of a Total Hip Arthroplasty (THA) is to reduce pain by reproducing the hip joint mechanical properties using artificial implants. This work addresses the ultrasound based navigation of THA, with a focus on the femoral implant. Using a calibrated 3D ultrasound probe, the aim is to image and recognize the femur after implant insertion, then to provide quantitative and visual navigation instructions for optimal implant placement. US bone interfaces are estimated per line of sight, then mapped to CT model profiting from the femur symmetry. The inaccuracy of the proposed navigation system is quantified in clinical terms. The obtained runtimes and accuracies make the proposed pipeline worthy to be tested in the OR. Once the proposed pipeline succeeds the intraoperative challenge, navigated bone tumor ablation and total shoulder arthroplasty can profit from our work.
