Osteoporosis is the most common reason for a broken bone among people who are old.Bones that commonly break include the back bones, the bones of the forearm, and the hip.Until a broken bone occurs there are typically no symptoms. Bones may weaken to such a degree that a break may occur with minor stress or spontaneously. Chronic pain and a decreased ability to carry out normal activities may occur following a broken bone. It was estimated that approximately 74,000 new fragility fractures were sustained in Switzerland in 2010, comprising 14,000 hip fractures, 11,000 vertebral fractures, 13,000 forearm fractures and 36,000 other fractures (i.e. fractures of the pelvis, rib, humerus, tibia, fibula, clavicle, scapula, sternum and other femoral fractures).
The burden of fractures in terms of costs (excluding value of QALYs lost) in Switzerland in 2025 was estimated to increase by 29 % to CHF 2,642 million. Though the uptake of osteoporosis treatments increased from 2001, the proportion of patients aged 50 or above who received treatment remained at low levels in the past few years. The majority of women at high fracture risk do not receive active treatment.
