Bone bending prevents fractures

the Royal College of Veterinary Medicine, in collaboration with researchers from institutions such as the Institute of Collomes and Interfaces of the German Magpies, have revealed how bones, as an organ, regulate their shape and number to protect themselves from fractures.
in a lifetime, bones can change shape by regulating bone formation and re-absorption, which is usually a response to the compression, stretching, and distortion of bone strength during daily exercise and exercise. The purpose of this shape is to reduce the risk of fractures.
have known that the bone's fold resistance is based on the engineering principle that a completely straight shape is the ideal shape. But if the purpose of changing shape is to prevent fractures, why do most people's bones bend?
researchers used high-resolution microcomputer fault scans to monitor changes in the shape of the entire bone over time when it was highly exposed to known forces. The team also quantified three-dimensional bone formation and bone absorption, and their relationship to local stresses in bone tissue caused by physiological forces.
results show that the bone's response to these forces changes along its length, making most of the bone more curved, and that these shape changes are very long-term. The researchers found that the bending process needed to be highly targeted, and that some short-term changes could be rapidly lost through re-absorption. The paper was published recently in Scientific Progress.
using precise mapping over time, the researchers found that reversible and preservable bone changes could be distinguished based on whether their initial goal was local re-absorption or formation. But to the team's surprise, the increase in bone bending was not related to local stress levels.
some of the bone improvements associated with exercise will gradually disappear, the increase in curvature creates an inne within warning mechanism that predicts how future bones will respond optimally to physiological forces, the researchers said. In addition, the study suggests that "intelligent" bone therapy, which interacts with physiological forces to selectively keep the whole bending to resist fractures, would be preferable. For example, existing osteoporosis treatments do not target the bone regions that contribute the most to bending strength, but rather have a general anti-resorbentment/promote formation effect.
