Bone healing is the process by which damaged or broken bones are repaired and restored to their original strength and function. This process involves several stages, including inflammation, soft callus formation, hard callus formation, and remodeling. Various factors can affect the rate and success of bone healing, such as the individual's age, overall health, nutrition, and the severity of the injury. Researchers are studying ways to improve bone healing, such as using bioactive materials, growth factors, and stem cells to enhance the regeneration of bone tissue. Understanding the mechanisms of bone healing is essential for developing effective treatments for fractures, osteoporosis, and other bone-related conditions.
