The pros and cons of intramedullary nailing of fractures, the cons of intramedullary nailing of fractures are that the intramedullary nail does not completely dissect and reset the fracture, and there may be mild displacement of the fracture while it is being fixed. The advantages of intramedullary nailing of fractures are that the nail is biologically fixed, disrupts the blood supply to the fracture end less, and causes less trauma from the surgical incision. Although anatomic repositioning of the fracture cannot be achieved, a good blood supply to the broken end of the fracture can facilitate healing. Also, during intramedullary nailing, there may be micro-movement at the fracture end, which is beneficial to fracture healing and is equivalent to mechanical stimulation within the physiological range, which promotes osteoblast activity, accelerates fracture and peri-fracture bone scab formation, and speeds up fracture healing.
