SESM3033 Orthopaedic Biomechanics
This module will provide an insight into the engineering based problems faced in orthopaedic biomechanics, through a detailed study of intact lower limb and the lower limb pre- and post- total joint replacement. You will gain an understanding of the structure of bone from the micro scale through to the full construct level, the major bones and tissues in the lower limb, their structure property relationships, and their kinematics. This knowledge will underpin your understanding of the replaced joint and its function, from an engineering perspective and from a surgical perspective. Finally, you will learn about the modes of failure of the replaced joint, and what can be done to prevent failure based on clinical experience, materials selection and design.
Aims and Objectives
To provide an insight into the engineering based problems faced in orthopaedic biomechanics, through detailed study of lower limb total joint replacement
Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- Material properties of bone and soft tissues from the micro level to the macroscopic level
- Mechanics of the lower limb
- Factors related to the design of hip and knee joint replacement
- Techniques used to assess the performance of joint replacement
- Apply engineering analysis techniques to orthopaedic biomechanics problems
- Evaluate the strengths and weaknesses of total joint replacement designs
- Make informed decisions as to the best method to assess the performance of total joint replacements
- To use standard software packages in problem solving situations
- Prepare brief technical reports
