This monograph explains the prototype of the biomimetic Multi-Spiked Connecting Scaffold (MSC-Scaffold) fixing in the periarticular bone, and the components of a new generation of entirely non-cemented resurfacing arthroplasty (RA) endoprostheses. It presents the design, rapid prototyping, and manufacturing of the prototype biomimetic MSC-Scaffold, including bioengineering CAD design and modelling, methods, and effects of the electro-erosion machining of the needle palisade and so forth.

Features:

• Presents the prototype of a new generation resurfacing endoprosthesis of the hip joint.
• Explains prototype endoprosthesis as the first worldwide biomimetic design.
• Insights into the entire process of bioengineering design and research on this prototype endoprosthesis.
• Proposes a novel way of fixation of the endoprosthesis components.
• Reviews structural and osteoconductive functionalisation of the interspike space of the prototype MSC-Scaffold.

This book is aimed at professionals and graduate students in biomedical engineering, endoprosthesis engineering and surgery, and biomaterials.
About the Author:

Ryszard Uklejewski, Ph.D., Eng, PhD, MD is a Professor of Biomedical Engineering. He received an MSc from Poznan University of Technology, Poland (1974), and a Ph.D. at the Technical University of Lodz (in Electromechanics, 1979), and studied mathematics (1976-1980) at the University of Lodz, Poland. He is also a qualified medical doctor (1996, Karol Marcinkowski University of Medical Sciences in Poznan, Poland), and received the PhD in Medicine (in Endocrinology) at the University of Medical Sciences in Poznan (2010). He worked (1974-1996) in the Department of Mechanics and Acoustics of Porous Materials at the Institute of Fundamental Technological Research, Polish Academy of Sciences. In 1995 he received the Habilitation in Biomedical Engineering from the Institute of Biocybernetics and Biomedical Engineering, Polish Academy of Sciences with a thesis on bioelectromechanics of porous bone filled with physiological viscous ionic fluid. He works (1997 til now) at the Kazimierz Wielki University in Bydgoszcz (Poland) as the Head of the Department of Medical Bioengineering Fundamentals in the Institute of Technology, currently in Chair of Constructional Materials and Biomaterials at the Faculty of Materials Engineering. His main research areas are structural-biomechanical biocompatibility of bone-implant interface on the basis of the modern two-phase poroelastic biomechanical model of bone tissue and of the theory of poroelastic materials, bone tissue biomechatronics, and the endocrinology of growing human skeleton. He is the author of more than 180 research publications, the inventor of the patent on the non-invasive method of determination of density and poroelastic parameters of osteoporotic long bones, and the head of two research projects of the Polish Ministry of Science and the National Science Centre Poland on the development of prototypes of non-cemented RA endoprostheses (invented by Professor P. Rogala), realized in Poznan University of Technology. He is a member of the American Biographical Institute Research Association, the European Federation for Research in Rehabilitation, Polish Society for Biomaterials, a former member of AAAS and NYAS (for at least 10 years); is included in "2000 Outstanding Scientists of the 20th Century" by International Biographical Centre of Cambridge, UK.

Piotr Rogala, MD, Ph.D. is an Associate Professor of Orthopaedic Surgery in the Department of Spine Surgery, Oncologic Orthopaedics and Traumatology of Karol Marcinkowski University of Medical Sciences in Poznan (Poland) and in the Institute of Health Sciences, State School of Higher Education in Gniezno (Poland) with more than 30 years of international clinical experience (France, Tunisia, Republic of South Africa), and the orthopaedic biomechanics Consultant in the Department of Medical Bioengineering Fundamentals, Kazimierz Wielki University in Bydgoszcz (Poland). He is the inventor and patent owner of the new model of resurfacing arthroplasty endoprostheses and the author of the original concept of the multi-spiked connecting scaffold (MSC-Scaffold) for fixation of resurfacing arthroplasty components in surrounding bone with minimally invasive operating procedures. He is a member of several international scientific associations (European Federation of National Associations of Orthopaedics and Traumatology, European Orthopaedic Research Society, European Federation for Research in Rehabilitation, etc.). He is particularly interested in orthopaedic biomechanics, the etiopathology of adolescent idiopathic scoliosis, and clinical genetics of bone diseases; The author of more than 170 research publications, the head of two research projects of the Polish Ministry of Science in the field of clinical orthopaedics and genetics; is included in Encyclopaedia Britannica, USA.

Mariusz Winiecki, PhD-Eng, is an Assistant Professor in the Chair of Constructional Materials and Biomaterials at the Faculty of Materials Engineering at the Kazimierz Wielki University in Bydgoszcz, Poland. In 2001 he received the MSc in Mechanical Engineering (specialization in Mechatronics) at Poznan University of Technology, Poland, and in 2006 he received PhD in Mechanical Engineering at Poznan University of Technology, Poland, for the PhD thesis on the investigation of the micro-geometrical constructional properties of porous endosseous implants and the influence of these properties on the strength of the bone-implant model fixation (PhD supervisor: Prof. R. Uklejewski). In 2007 he finished Postgraduate Studies in the field of Biomaterials Engineering at AGH University of Science and Technology in Cracow, Poland and since 2007 he is a member of the Polish Society for Biomaterials. His main research areas in the field of biomaterials engineering are the engineering of bone-implant interfacing, design and implant surface functionalization towards improving the conditions for osseointegration. He has achievements in works of the interdisciplinary research group that has designed, prototyped and manufactured in the selective laser melting technology, and developed through bioengineering research, the essential innovation in fixation of components of a new generation of entirely cementless resurfacing hip arthroplasty endoprostheses in the subchondral trabecular bone by means of the biomimetic multi-spiked connecting scaffold - he was a key investigator in two research projects of the Polish Ministry of Science and the National Science Centre Poland, concerning on the development of prototypes of non-cemented resurfacing arthroplasty endoprosthesis, realized at Poznan University of Technology. He is the author of more than 90 scientific papers.
