The Correct Answer and Explanation is:
Correct Answer: True
Explanation
Bones naturally begin to heal immediately after a fracture. When a bone breaks, the body quickly initiates a complex healing process to repair the damage. This process begins almost instantly, typically within a few hours of the injury.
The first stage of bone healing is the inflammatory phase, which begins within minutes to hours after the fracture. Blood vessels that are torn during the injury bleed into the surrounding tissues, forming a hematoma (a localized collection of blood). This hematoma serves two important purposes: it helps to stabilize the fracture temporarily and provides a rich supply of inflammatory cells, nutrients, and growth factors necessary for healing.
Next, the body activates osteoclasts (cells that remove damaged bone tissue) and osteoblasts (cells that build new bone). The hematoma is gradually replaced by a soft callus made of cartilage and fibrous tissue within the first week or two. This is the reparative phase. During this time, new blood vessels grow into the area (a process called angiogenesis), and cells begin producing collagen and other materials to create a scaffold for new bone.
Over the following weeks, this soft callus is replaced by a hard bony callus as minerals like calcium and phosphate are deposited. Finally, in the remodeling phase, which can last for months or even years, the bone is reshaped and strengthened. The newly formed bone is remodeled to restore the bone’s original structure and function, often becoming just as strong or even stronger than it was before.
Therefore, it is true that bones naturally begin to heal immediately after a fracture. However, proper alignment, stabilization, and medical care are crucial to ensure complete and effective healing.
