Prosthetic Devices

Course objectives

Course Objectives The course of study aims to train students of the Master's Degree course in Biomedical Engineering and to provide the fundamental knowledge, skills and methodologies relating to the design of a prosthetic medical device, with particular reference to endoprostheses. The course will provide the theoretical and computational tools necessary to address the 3D modeling and biomechanical analysis of an endoprosthesis model, in particular osteoarticular and osteosynthesis. The objectives of the course intend to develop in the students the ability to identify the design specifications of an endoprosthesis, the approach to design, the identification of technological solutions compliant with clinical specifications, verifying that the proposed solution guarantees the functionality of the prosthesis. Learning Outcomes At the end of the educational path the student must be able to acquire professional, decision-making and operational autonomy aimed at dealing with, identifying and managing relationships with medical staff by proposing solutions, where possible immediate, or short and medium-term alternatives. The learning ability is stimulated by a training course that alternates methodological principles, application examples and in-depth exercises. In particular, the student will know: • critically know the fundamental principles for the design and virtual prototyping of elementary prosthetic structures; • draw up the technical project specifications from the morphological, structural, functional analysis taking into account the interaction with biological tissues for the setting of a virtual pre-operative plan; • formulate and interpret the results from the biomechanical analysis of the 3D models for the validation of the identified design solution.

Prerequisites
The topics relating to the Solid and Structural Mechanics and Fundamentals of Biomechanics exam are essential in order to understand the contents and achieve the learning objectives of the course.
Books
TEXTBOOK and SCIENTIFIC PUBLICATIONS • Lecture notes by the Teacher. • Lisa A. Pruitt, Ayyana M. Chakravartula, Mechanics of Biomaterials: Fundamental Principles for Implant Design, Editore: Cambridge University Press
Frequency
frequency modality is optional.
Exam mode
For the formative evaluation, the presentation of the progress of the 3D model aimed at pre-operative surgical planning is expected in the classroom. While for the summative evaluation, the exam is conducted orally and involves both the discussion of the results obtained from the analysis of the 3D model and the topics covered in the classroom.
Lesson mode
The activities are organized in frontal lessons and classroom exercises through group activities supported by seminars held by expert professionals in the sector also relating to the development of experimental tests, certification and technology transfer.
