The sequelae of sacral fracture are generally related to the degree of displacement of the fracture, which is different. 1. Mild displacement: if the sacral fracture is mildly displaced or not obviously displaced, it will not leave obvious sequelae, and only need to take strict bed rest and oral medication to promote fracture healing in the early stage, and there will be no obvious sequelae after recovery. 2. Moderately displaced: If the sacral fracture is moderately displaced and the sacral plexus nerve is damaged, it will cause numbness, pain, weakness and atrophy of the lower limbs, and in severe cases, it will lead to the activity of the lower limbs in the later stage. 3. Severe displacement: If there is severe displacement and the blood vessels of the sacral plexus are damaged, hemorrhage or even shock will occur. If the displacement is not corrected, it will also lead to asymmetry of the pelvis, which will lead to the short and long legs during activities. If there is a sacral fracture, it is recommended to go to the hospital in time to improve the sacral plexus CT, MRI and other tests, to clarify the diagnosis, and follow the doctor’s instructions for treatment.
