About the Project

Background

Scoliosis is a 3-dimensional deformity of the spine that develops in child/adolescent life and can deteriorate during skeletal growth and especially in periods of rapid skeletal development such as around puberty. The overall prevalence has been has been reported to be between 0.5-5%. Scoliosis can severely affect the quality of life of many patients; it may lead to multiple impairments and creates a heath inequality, requiring treatment. Females are 8 times more likely to progress to a curve that requires treatment in comparison to males. There is no consensus among spinal surgeons on the use of correction techniques in the treatment of scoliosis. For example, some many surgeons prefer approaches which are thought to provide good scoliosis correction though they may pose long-term risks in comparison to low risk approaches that may provide comparable results (e.g. all pedicle screw correction rather than hybrid instrumentation)(Tsirikos and Subramanian 2012). Similarly there are many other questions related to treatment and instrumentation (Tsirikos 2019) that remain debated and can be answered using computational modelling (Pankaj 2013; Scott et al. 2020)

Aims

-Develop computational models using the imaging data (CT and MRI) to simulate the anatomy of an adolescent scoliotic spine across the different types of curves which represent the common patterns seen in clinical practice.

-Undertake a modelling studies to evaluate intra-operative corrective forces required in scoliosis correction of the spine to answer a range of clinical questions.

-Compare the computational results with patient reported outcomes using the Scoliosis Research Society (SRS)-22 validated questionnaire for adolescent idiopathic scoliosis.

-Develop software to recommend an optimum correction approach for a given clinical scenario.

Training Outcomes

-Present and critique the state-of-art with respect to scoliosis and its treatment approaches.

-Develop complex geometry of the scoliotic spines from 3D scan data.

-Describe the mathematical constitutive models of components involved in modelling.

-Describe loadings experienced by the spine due to different correction approaches and instrumentations.

-Learn to generate, curate and analyse large datasets.

-Master techniques for data analysis obtained from computational modelling, imaging and patient reported outcomes.

-Work in a team and become self reliant for acquiring resources required for research.

-Present research in international conferences and write journal papers.
