Uncover the form-function relationship of paediatric hip joint deformities using personalised FEA models

To accelerate the generation of patient-specific bone and joint modelling, our team have developed statistical shape and density models of children lower limbs pelvis, femur and tibia. These paediatric population-based models are capable of predicting the form-function relationships of the musculoskeletal system in children. It bridges the gap between inaccurate generic models and subject specific models by predicting children’s bone automatically and accurately in a matter of seconds. These paediatric population-based models of bone shape and bone mineral density prediction can be used for mechanical analyses. FEA models have been used extensively in adults but only few have been developed on children and young adults. An understanding of bone morphology and mechanics during childhood and adolescence will inform mechanisms of bony deformation in musculoskeletal disorders and predict future complications from orthopaedic surgical intervention.

As a student you will develop a paediatric hip joint FE model based on a previously developed statistical shape and density model of the pelvis and femur which will inform bone geometry and material properties. Pre and simulated post-surgery bone stress, strain and joint contact forces distribution will be calculated from this customised shape-density hip FE model. The pre-surgery FE model will inform the surgeon on the abnormal joint contact forces and bone stress distribution within the hip joint of a patient. Using this model, the surgeon can perform ‘virtual surgeries’ to aid their treatment decision-making.
