Both open fractures and closed fractures are not easy to perform internal fracture fixation surgery as early as possible, so why? Open fracture is a rupture of the skin or mucosa of the bone part, the fracture is connected with the outside world, the wound contamination is serious, plus the local soft tissue contusion is not easy to heal, in addition, the fracture internal fixation are foreign body implantation brings the risk of infection, so the pathological changes are more complex, the treatment is more difficult, if the surgery is cut to reset will increase the soft tissue damage, resulting in local resistance is reduced, further increasing the chance of infection, often constantly fracture can not be healed, making the condition more difficult. The fracture will not heal, which will aggravate the soft tissue damage and make the condition worse. The correct method is to change an open fracture into a closed fracture, and then treat the fracture after the local soft tissue has healed. The closed fracture itself has severe soft tissue edema, and in serious cases, osteofascial compartment syndrome may occur, resulting in limb necrosis, plus the trauma of surgical incision and repositioning will make the soft tissue congestion and edema more serious, and the incision will not heal for a long time after surgery (several months to a year), and in serious cases, the compression of blood vessels and nerves will lead to blood circulation disorders, resulting in tissue ischemia, hypoxia and necrosis. The correct treatment is to elevate the affected limb and wait for the swelling to subside before performing internal fixation of the fracture.
