Pros and cons of fracture intramedullary nailing, The disadvantage of fracture intramedullary nailing is that intramedullary nails do not completely anatomically reset the fracture and there may be mild displacement while the fracture is being fixed. The advantages of intramedullary nail fixation of fractures are that it is a biological fixation with less disruption of the blood supply to the fracture site and less trauma from the surgical incision. Although the fracture cannot be anatomically repositioned, a good blood supply to the fracture can promote healing. At the same time during intramedullary nailing fixation there may be micro-movement of the fracture broken end, this micro-movement is beneficial to the healing of the fracture, which is equivalent to mechanical stimulation within the physiological range, which can promote the activity of osteoblasts, accelerate the formation of bone scabs around the fracture and fracture, and accelerate the healing of the fracture.
