Risk of Bone Fracture due to Spaceflight-induced Changes to Bone - NASA

Exposure to altered gravity causes skeletal changes, which can result in compromised bone strength during and after spaceflight, increasing the risk of fracture. Bone fracture in-mission depends on expected loads and degree of skeletal fragility. Countermeasures such as exercise, adequate nutrition, and medications are needed in order to prevent demineralization, especially during long-duration missions such […]
