How to determine the severity of the condition after a fall to the waist needs to be determined by a medical professional. Usually, the doctor can determine and confirm the diagnosis from several aspects, such as medical history, symptoms, physical examination, and imaging tests. 1. Medical history: By asking about the medical history and the course of the injury, a preliminary judgment of the severity is made. 2. Symptoms and signs: Determine the exact location of the injury through the patient’s complaints, and find out whether the patient’s vital signs are stable and potentially dangerous by measuring temperature, pulse, respiration and blood pressure. 3. Physical examination: Through physical examination, check the wound site, understand the severity of the patient’s loss, and determine whether it is a soft tissue injury or a possible fracture. If there are symptoms such as severe pain in the waist, numbness and weakness, paraplegia, etc., it should be suspected that there are lumbar vertebrae fracture and spinal cord injury. 4. Imaging examination: Based on questioning and palpation, combined with auxiliary examinations such as X-ray, CT, MRI and other imaging examinations, the severity of the fracture or spinal cord injury can be accurately determined and diagnosed. After falling on the waist, if the pain is severe, or the limbs appear numbness and weakness and other symptoms, you should immediately lie down to avoid secondary injury, go to the emergency room of the hospital in a timely manner, cooperate with the doctor to carry out all kinds of examinations, and give standardized treatment.
