Through the method of a clinical randomized controlled trial, patients meeting the study criteria are randomly assigned to either the Denosumab treatment group or a placebo group. After a treatment period of 12 months, the differences in osteoporosis and sarcopenia-related baseline assessment changes between the two groups are compared. This is to explore the effect of Denosumab in treating osteoporosis and its impact on sarcopenia. The goal is to evaluate the efficacy of Denosumab in treating osteoporosis in the domestic population and its related impact on sarcopenia, with the aim of providing an effective treatment option for the domestic population suffering from 'osteoporosis-sarcopenia syndrome.
