Core Tip

Core tip: The bones of streptozotocin-induced diabetic Wistar rats are more fragile with reduced toughness, characterized by a reduction in the capacity to absorb energy and with lower forces required to induce fracture in comparison to those in the control group. Our findings confirm previous studies and lend weight to the literature describing the detrimental relationship between the mechanical properties of bone subjected to diabetes mellitus. Further research needs to be conducted to ascertain whether uncontrolled diabetes in a human population affects the structural and biomechanical properties of bone.
