Biomechanics of internal fixation methods for ankle fusion

Ankle fusion is a common treatment for advanced ankle arthritis to relieve pain and improve functional outcomes. However, there is a reported non-union rate of 5-37%, requiring further surgery or an ankle replacement. Moreover, there are several options for internal fixation, with no consensus on the number of screws, orientations, and placement in ankle fusion surgery.

This project aims to develop validated computational models of the foot and ankle, and investigate the biomechanical parameters impacting successful bone healing while reducing the risk of fixation failure.

The project will involve parametric analysis of participants’ data, finite element analysis and mechanical testing. Hence, the candidate will be consulting with collaborators in orthopaedic surgery, bioengineering, mechanical engineering and the Insigneo Institute. The candidate will gain a unique opportunity to carry out research in an exciting interdisciplinary project to answer important clinical questions.

Requirements

We are looking for applicants who are eager to develop new skills and apply their existing knowledge. You should be excited to learn and develop new technology, be passionate about the subject and look to be creative in your work. In addition, you should:

– Hold (or will receive this year) a master’s degree (or equivalent, e.g. MEng) at merit/distinction level, or a first class/ upper second (2:1) class honours degree in biomedical engineering, mechanical engineering, applied maths or a related field.

 – Proficiency in finite element analysis software (e.g., Abaqus, Ansys etc) and programming languages such as Python, MATLAB etc.

– Strong analytical and problem-solving skills.

– Good interpersonal and organisational skills, and the ability to work as a team player.

Interested candidates are strongly encouraged to contact Dr Vee San Cheong (v.cheong@sheffield.ac.uk), to discuss your interest in and suitability for the project prior to submitting your application.
