Study on the Intervention Effect of Denosumab on High-Risk Patients With Osteoporotic Fractures in Type 2 Diabetes

Обзор

This study will conduct a randomized controlled trial targeting patients with type 2 diabetes and a high risk of fractures. The aim is to evaluate the intervention effect of denosumab combined with edilossobulin on patients with a high risk of osteoporotic fractures due to type 2 diabetes, as well as its impact on bone density, bone turnover indicators, the risk of new fractures, and the risk of hypocalcemia. This will provide scientific evidence for clinical diagnosis and treatment, and offer important clinical research evidence for formulating national health policies.
