Abstract
This thesis investigates the mechanical behaviour of immature porcine bone to enhance our understanding of paediatric skeletal injuries, particularly in the context of child abuse. Due to the limitations of using human paediatric bone, this research uses immature porcine bone as a model. The study includes a comprehensive analysis of immature porcine bone, examining its intrinsic and extrinsic properties under various loading conditions and characterising certain resultant fracture patterns. The findings reveal age-related trends in immature porcine bone's mechanical behaviour, although direct comparisons to human infant bone were limited. Furthermore, a large scatter of the data suggests caution in interpreting the results. Despite so, the research does indicate certain non-statistical trends that immature porcine cortical bone does exhibit age-related trends in strength (flexural strength) and stiffness (flexural modulus). Bone type (femur and humerus) was identified to not predominantly be a determining factor. Loading rate did influence the mechanical response but again, the scattered data suggest caution in interpretation. Additionally, different loading types generated distinct fracture patterns in immature porcine long bones. These results contribute to a deeper understanding of immature bone biomechanics and fracture characteristics. While acknowledging limitations in directly translating the findings to the larger arena of immature bone research, this work provides valuable insights for future studies and has the potential to aid in the development of more accurate assessments of paediatric skeletal trauma.
