$Natural healing process of fractured bones. (A) Healing begins with a collection of blood and inflammation at the fracture site. (B) Soft callus (purple) is formed, which develops into the bidirectional growth plate at the concave side of the fracture site. (C) The growth plate drives bone growth in opposite directions. The result is a jack-like mechanical effect that moves the fragments toward straightening (red arrows). (D) New bone tissue is formed (orange). (E) The shape of the bone is fine-tuned by rem$
