This seminar presents how an index of wear can be computed from motion analysis data, combining estimated/measured slip velocity and contact forces. Different datasets with bi-pane fluoroscopy or X-ray, instrumented implants, and clinical gait analysis with musculoskeletal modeling are analyzed. This index of wear is used to investigate the effect of the implant design (total hip arthroplasty with single or double mobility, total knee arthroplasty with or without cruciate retaining) and of the activity (gait, sit to stand…).
Raphael Dumas is Visiting Professor under the program of the ISA Visiting Fellowship (https://site.unibo.it/isa/en). Raphael Dumas received his M.Sc. in Mechanics (INSA Lyon, 1998) and Ph.D. in Biomechanics (ENSAM Paris, 2002) and is currently a Research Director at the University Gustave Eiffel. He is team leader in the Laboratory of Biomechanics and Impact Mechanics and in the International (French-Canadian) Joint Laboratory – EVASYM. His research interest is in 3D multi-body modeling of the human musculoskeletal system applied to joint pathologies, postural and gait impairments. Raphael Dumas currently serves on the board of 3D Analysis of Human Movement (Technical Group of the International Society of Biomechanics) and has served on the boards of the Francophone Societies of Biomechanics and of Motion Analysis for Children and Adults. He has coordinated several international (e.g., French-Taiwanese, French-Australian, French-Italian) and nationally funded projects and contracts with orthopedic and motion analysis companies. He has supervised 20 doctorates and 6 post-doctorates. He has authored or co-authored more than 140 archival journal full papers, 10 book chapters, 200 congress proceedings, and 2 patents.
