Impact Of Diabetes On Fall Related Lower Limb Fractures, Bryce M. Bellon, Daniel Salinas, Patrick De La Torre Shutz, Hunter Butler, Sean Corcoran, Kelsey Baker

Research Symposium

Background: Diabetes is a disorder that affects many Americans, characterized primarily by hyperglycemia due to either insulin resistance or lack of insulin secretion. This condition not only impacts blood sugar levels but also has significant effects on bone health. In diabetes, bone density is often decreased due to reduced osteoblast activity, which is responsible for bone formation, and increased osteoclast activity, which leads to bone resorption. This imbalance accelerates the breakdown of bone. Additionally, diabetics frequently suffer from lower extremity arterial disease (LEAD), which results in poor vascularization of the lower limbs. These factors contribute to an increased risk of …
