Detailed explanation-1: -Broken bones usually heal and get strong again, but not always. When broken bones don’t heal back together it is call non-union, and that can cause a lot of problems.

Detailed explanation-2: -If you’ve ever seen a real skeleton or fossil in a museum, you might think that all bones are dead. Although bones in museums are dry, hard, or crumbly, the bones in your body are different. The bones that make up your skeleton are all very much alive, growing and changing all the time like other parts of your body.

Detailed explanation-3: -Low levels of vitamin C, vitamin D, and calcium may prevent a bone from healing. An infection in the bone, which is called osteomyelitis, may also delay or prevent healing. A bone can become infected if bacteria from a wound on the surface of the skin travel through the bloodstream to the bone.
