How a Broken Bone Heals Itself

The recovery process for a broken bone involves four distinct biological stages that transform a fresh injury into a fully restored structure. The initial phase is inflammation, where the body triggers an emergency immune response and forms a protective blood clot around the break. This is followed by the creation of a soft callus, a flexible bridge of cartilage that stabilizes the bone ends. During the third stage, this bridge mineralizes into a hard callus, providing a firmer connection that is visible on medical imaging. Finally, bone remodeling occurs as the body reshapes the area and replaces temporary tissue with permanent, high-strength bone. Successful rehabilitation requires patience and adherence to medical advice, as these overlapping phases can take months to complete.
