Biotribology in arthroplasty: In-silico wear prediction in lubricated total hip replacements

Nowadays, the patient group undergoing total arthroplasty includes younger and more active people who require a broad range of motion and a longer service lifetime for the replaced joints. Wear is still one of the main issues affecting joint prostheses endurance, causing loosening and, eventually, implants failure. Actual in-vitro wear tests (simulators) have a long duration, are very expensive and does not take into account all the possible daily activities of the patients. In this scenario the possibility to use accurate in-silico tribological and dynamical models of the (bio) tribo-systems under investigation allows to overcome the actual testing procedures and could contribute as tool for a more and more accurate tribological design of human prostheses.

The talk is devoted to give an overview of the last research results on total hip replacements, underlining some open problems in contact mechanics, numerical stress-strain analysis, musculoskeletal multibody modelling, synovial lubrication modelling (boundary/mixed, hydro-dynamic and EHD), with the aim to establish future research cooperation with the Colleagues attending Biomodlore 2021.

Alessandro Ruggiero since 1999 to 2005 was Assistant Professor of Applied Mechanics with the Department of Mechanical Engineering, University of Salerno, where he has been an Associate Professor with the Department of Industrial Engineering since 2005 till today. In 2017 he received the National qualification to Full Professor in Applied Mechanics. He authored more than 200 scientific papers on indexed international journals and national and international proceedings. He serves as Editor, member of the Editorial Board and reviewer for many prestigious international scientific journals and as evaluator of national and international research projects. He cooperates with numerous international Universities and prestigious Research Centers; he is member of the IFToMM Technical Committee for Tribology. Recently was elected national coordinator of the Italian AIMETA association -Tribology Group-. His current research interests are focused on (bio) tribology, mechanical measurements, dynamics of mechanical systems and biomechanics.

Artificial intelligence solutions for health and wellness

The recent advances in Artificial Intelligence (AI) including the use of data science and techniques such as deep learning are having a great impact on Healthcare and understanding of wellness. The use of AI as related to Healthcare will be discussed in the context of Health 4.0. Examples include applications to predictive analytics for patient care, medical image analysis and annotation, document and social media text analysis.  This work is part of a larger project which integrates a variety of information sources from clinical data, social media, and professional literature to better guide our understanding of health and wellness. The AI techniques used include Deep Learning, NLP and ANN, and applied to doctors’ annotation and public sentiment combined with medical literature. Imaging work has significantly reduced the effort of medical professionals to allow them to focus on the patient. We shall also discuss emerging topics as they relate to e-health, such as Industry 4.0, Precision Medicine, Mobile Health, 5G, Big Data, and Cyber-Physical Systems.
