Projet 16 – B-Lab: Advanced Robotic Testing of Surgical Devices - Pilot project Auteurs Dr Nicolas Holzer, Division of Orthopedic Sugery and Muskuloskeletal Traumatology, Department of Surgery, Geneva University Hospitals; Dr Florent Moissenet, Kinesiology Laboratory, Faculty of Medicine, University of Geneva, Geneva University Hospitals Partenaire HEPIA HES-SO, Genève, Suisse Résumé du projet The present B-Lab project is a new research facility developed as a collaboration between 1) the Division of Orthopedic Surgery and Muskuloskeletal Traumatology of the Department of Surgery of the Geneva University Hospitals (Dr Holzer) 2) the Unit of Teaching in Anatomy of the Geneva Faculty of Medicine (Dr Beaulieu) and 3) the Kinesiology Laboratory of the University of Geneva (Dr Armand).

The scope of the research program is the creation of a unique platform for biomechanical evaluation of safety and efficacy of surgical devices using advances in the fields of a) robotised biomechanical testing, b) motion capture and c) imaging and three-dimensional image reconstruction.

The goal is the development of an in vitro models of human joints closely reproducing in vivo conditions and complexity of motion. The proof of concept study is focused on acromioclavicular traumatic injuries. The primary objective is the validation of a first model of the complete shoulder girdle by comparison with unique data acquired in vivo.

Secondary objective is the assessment of safety and efficacy of a new surgical procedures for acromioclavicular stabilization of traumatic injuries.

Introduction Evaluation of safety and efficacy of surgical devices relies on biomechanical testing in standardized conditions in vitro. Frequent limitations of biomechanical studies include the necessity to artificially isolate parts of complex articular systems and to analyze simple trajectories. Data acquisition furthermore often requires to constrain study specimens in non-physiologic ways. Those limitations introduce potentially important bias when extrapolating results to predict behavior of surgical devices in vivo.

Advances of robotics allow to reproduce complex motion in vitro, overcoming limitations of previous equipment and emerges as a new gold standard. Association with advances in the fields of motion capture and image three dimensional reconstructions potentially opens new fields of investigation. Creation of a facilities giving access to those technologies represent a unique opportunity to attain a leading position in the field of surgical devices research and development.

Innovation The innovation of the whole research program is to establish a unique platform for multimodal biomechanical evaluation of orthopaedic surgical devices using advances in 41
