The S3guidelines on the prophylaxis, diagnostics and treatment of osteoporosis 2023 were completely revised and updated between 2021 and 2023 in accordance with the Association of the Scientific Medical Societies of Germany (AWMF) regulations. The guideline committee consisted of delegates from the 20specialist societies of the Umbrella Organization Osteology (Dachverband Osteologie, DVO) as well as delegates from the German Society of General Medicine and Family Medicine (DEGAM), the German Society for Nephrology (DGfN) and the Federal Self-help Association for Osteoporosis (BfO).The guidelines focus on preventive measures, diagnostic procedures and treatment approaches for osteoporosis in men aged50 years and over and postmenopausal women. The main aim is the optimization of care processes, reduction of fracture incidences and maintenance or improvement of the quality of life and functional capacity of patients affected by fractures. Amajor update to the guidelines includes the introduction of anew risk calculator that can take more risk factors (n = 33) into account and that can estimate the risk of vertebral body and proximal femoral fractures for a3-year period (previously 10years). This results in new thresholds for diagnostics and treatment. The programmed app is currently not yet certified as a medical product and apaper version is therefore currently available for patient care with the planned integration of aweb-based version of the risk calculator. From the perspective of trauma surgery, the recommendations and innovations for manifest osteoporosis are of particular clinical importance. The focus of the DVO guidelines update is therefore on the implementation of secondary fracture prevention in trauma surgery, orthopedic and geriatric traumatology in the clinical and practical daily routine.
