Biomechanics
A registrar is revising basic science concepts for the FRACS Part I examination. During a tutorial on biomechanics, the consultant asks about the mechanical properties of bone and how these relate to fracture patterns and implant design. The discussion covers stress-strain relationships, material properties, and how bone responds to loading. Regarding bone biomechanics:
