Biography Dónal is the newest member to the BTC research group. In 2005 Dónal McDonagh obtained a Bachelor Degree with first class honours in Manufacturing Engineering at ITT Dublin, subsequently he continued his studies in University Limerick, completing a taught master in Computer Aided Engineering Product Design in 2007 with distinction. After his studies Dónal entered the medical device industry working in product development for Trulife healthcare spanning 3+ years in the Pressure Care department. In this role Dónal was heavily involved in development of Class I medical devices. Dónal continued to work in product development in subsequent roles, gaining experience working with heavy engineering in ESIDock Ltd, a start-up based in Dublin’s city centre and also Innalabs Ltd, a start up originally based in Kyiv Ukraine but now operating in Blanchardstown Dublin. Innalabs build inertial sensors and Dónal was heavily involved in the transfer of knowledge from the old facility in Kyiv to the new operation in Dublin. In both these roles Dónal was seen as a key contributor to product design and development, as well as setting up a functional R&D department and product development framework. In Nov 2013 he was awarded a Postgraduate Scholarship by the ITTD to study towards a MEng at the Bioengineering Technology Centre in ITT Dublin. 
Project Summary Adolescent idiopathic scoliosis (AIS) is a deformity of the spine, which may require surgical correction by attaching a rod to the patient’s spine using screws implanted in the vertebral bodies. This form of spinal surgery is termed Posterior Dynamic Stabilization and effectively fuses vertebra of the spine together using rods and screws. Originally the goal was to achieve a rigid construct along the vertebra, now the goal is to have a degree of flexibility. These devices are designed with the intent of providing stabilisation of the spine, eliminating pain and preserving the integrity of the facet joints and the inter-vertebral disc. Surgeons achieve an intra-operative reduction in the deformity by applying both compressive forces and corrective moments across the inter-vertebral disc spaces while they secure the rod to the vertebra
Donal aims to build on the significant body of research completed by Nor Amalina. The aim of his study will take a three pronged approach to contrast the biomechanics of a normal spine to that of a surgically corrected scoliosis spine. The three approaches are to; quantify the surgical forces applied by the surgeon during the corrective procedure, physically investigate mechanical effects using the MTS Bionix Spine Simulatorand to simulate the effects using finite element models using Ansys. Correlating the results of both these methods will help to predict the stresses on the vertebral body and the implants post surgery
