Biomechanical analysis of additively manufactured interbody fusion devices (spinal cages)

Interbody fusion devices, or spinal cages, are implants inserted between two or more vertebrae and designed to encourage bone growth, or fusion, between them. Cage subsidence, when the implant migrates into the vertebral bodies, is one of the most common complications of interbody fusion surgeries (34% after three years). Patient specific spinal cages (PSSC) holds the potential to reduce cage subsidence by matching the exact geometry of the implant to the geometry of the endplate. Using a combined computational and experimental approach, we will assess the biomechanical performance of PSSC. In particular, via the finite element method, we will assess the effect of various lattices on stress-shielding, bone formation and risk of cage subsidence. The developed finite element model will be validated via a quasi-physiological experimental validation.

Applications are sought from excellent candidates and must hold a Bachelors or Masters in Mechanical Engineering, Biomedical Engineering or equivalent. Strong knowledge in finite element analysis and mechanical characterisation techniques is considered a plus. The candidate should be able to display a strong aptitude and enthusiasm for Engineering Research at undergraduate or postgraduate level.
