Hello, bone spur, the academic term is called bone spur, which is not a proper term in medicine, because it is neither completely composed of bones nor as sharp as a thorn. The correct medical name should be osteophyte. Bone spur is a natural aging phenomenon, which causes the wear and destruction of cartilage in joints for various reasons and promotes the repair, hardening and proliferation of bones themselves. Generally speaking, a long bone spur means that a person's spine has entered an aging stage. However, bone spurs are not the patent of the elderly. Many people have to sit and stand for a long time because of the change of working methods. If the posture is not correct, it is easy to make the young spine degenerate prematurely, thus inducing the occurrence of bone spurs.
