DR, CT, ultrasound, and angiography can be done after a left lower tibia fracture. A full-length DR film of the lower leg is needed after a left tibia fracture to prevent a lower tibia combined with a fracture of the upper fibula, which can be missed. CT examination of the lower leg is also needed, which can clearly show the position of the bone block after the fracture as well as the fracture line that is not shown clearly in the DR film. Lower limb vascular ultrasound can also be done to observe whether there is any damage to the blood vessels and whether there is any venous thrombosis in the lower limbs. If there is severe soft tissue contusion after calf fracture, weakened or disappeared dorsalis pedis and posterior tibial artery pulsation, and coldness of the foot, it is possible that there is vascular injury, and lower limb angiography can be done to observe the site of vascular injury and to provide a basis for subsequent treatment. If the left lower tibia fracture occurs inadvertently, it is recommended that the patient go to the hospital for medical examination, and regular treatment under the guidance of that doctor.
