The risks of open fracture surgery are usually the following: First, the risk of anesthesia, if some people are sensitive to anesthetic drugs, there will be anaphylactic reactions, serious anaphylactic shock, if very sensitive to anesthetic drugs, may also lead to acute respiratory and cardiac arrest, resulting in life-threatening. Second, damage to the limbs or nerves near the fracture, especially fractures of the spine, or fractures of the middle and lower humerus, can easily damage the local nerves, and in serious cases, may lead to the sequelae of limb paralysis. Third, damage to blood vessels, such as pelvic fractures or knee fractures, can easily damage the large blood vessels of the limb, leading to the possibility of local hemorrhage.
