Assessment of Bone Healing Using Ultrasound
Human bone has the remarkable capacity of remodeling and self repair through a complex regenerative healing process resulting in the gradual restoration of its mechanical properties and load bearing capacity . Fracture healing goes through three distinct stages: reactive phase which includes inflammatory phase and granulation tissue formation, reparation phase which includes callus formation and lamellar bone deposition, and remodeling phase in which woven bone is replaced by mature bone. Although surgical intervention and fracture immobilization facilitate healing, fracture healing is known to be a physiological process. The connective tissue membrane covering the bone determines the healing process of a fractured bone. This connective tissue is the primary source of bone cells responsible for generating new bone during growth and repair. The length of the healing process depends on the extent of the fracture. It takes up to three weeks for the majority of upper bodily fractures and it takes up to four weeks for lower body fractures.
