Fractures are classified as closed fractures or open fractures according to whether the fracture is connected to the outside world after the injury. The abnormal healing of fractures and some serious complications of fractures can have a significant impact on a person’s life. Complications of fractures include early complications and late complications. Early complications include: first, traumatic shock: due to more serious trauma induced fracture, there will be traumatic shock and life-threatening at the same time; second, infection: some open fractures are not cleared in time or not completely cleared, septic or some other anaerobic infection may occur, and even induce osteomyelitis, etc.; third, visceral injury: fracture can be combined with visceral injury, such as lung injury, The fracture can be combined with internal organ injuries, such as lung injury, liver and spleen rupture, bladder, rectum, urethra, etc.; fourth, important vascular injury: some serious open fractures or displaced closed fractures can combine with important vascular injuries, causing life-threatening conditions such as vascular shock; fifth, ischemic muscle contracture: it is a serious consequence of fascial septal area syndrome, such as supracondylar fracture of humerus and forearm double fracture, which can develop ischemic muscle contracture and Sixth, spinal cord injury: spinal fractures can be combined with spinal cord injury, resulting in impaired movement of the lower limbs or paraplegia; seventh, peripheral nerve injury: some fractures may also cause peripheral nerve injury, affecting nerve function; eighth, fat embolism: it is a rare and serious fracture complication that can be life-threatening. Late complications of fractures include: crushing pneumonia, decubitus ulcers, injurious ossification, traumatic arthritis, joint stiffness, and ischemic osteonecrosis, which can have a significant impact on a person’s life. Deformed healing of fractures is also very common in clinical practice. Due to less than ideal fracture management, poor alignment and alignment, deformed healing of fractures can occur, which can affect the function of the limb and have a certain impact on a person’s life.
