The basic science, in brief: Primary bone healing is lead by the formation of a so-called cutting cone (consisting of osteoclasts at the front of the cone to remove bone and trailing osteoblasts to lay down new bone) across the gaps to form a secondary osteon.escribe the differences between primary and secondary bone healing. escribe the differences between primary and secondary bone healing. The two mechanisms of bone healing are primary bone healing and secondary bone healing. (THIS IS JUST LIKE SKIN: you can sew it up or it can scab.).
All broken bones go through the same healing process. This is true whether a bone has been cut as part of a surgical procedure or fractured through an injury. The bone healing process has three overlapping stages: inflammation, bone production and bone remodeling. Inflammation starts immediately after the bone is fractured and lasts for several days. When the bone is fractured, there is bleeding into the area, leading to inflammation and clotting of blood at the fracture site. This provides the initial structural stability and framework for producing new bone.
