The document summarizes a seminar presentation on the utility of bone markers in the diagnosis and management of osteoporosis. It defines bone and describes its structure, formation, and resorption processes. It then discusses osteoporosis, its risk factors and impact. The document outlines diagnostic tools for osteoporosis including bone mineral density scans and bone markers. It describes markers of bone formation like bone alkaline phosphatase and osteocalcin, and markers of bone resorption like CTX and NTX. It concludes that bone markers are helpful complementary tools to static bone scans in detecting treatment effects and monitoring patients.
