The sciatic fracture is a relatively simple type of pelvic fracture, which is a stable fracture, and the pelvic ring is stable when it is not combined with other fractures. A simple sciatic fracture is characterized by pain at the fracture site, significant pressure pain, local edema, hemorrhage, palpable bone rubbing, and pain from sitting up and moving. Hemorrhagic shock and a huge pelvic hematoma will occur in combination with vascular injury, requiring timely blood and fluid anti-shock treatment, as well as further hemostatic treatment to recover. If this cannot be corrected in time, the broken vessel needs to be ligated by emergency exploration. When combined with nerve injury, the most common is combined with sciatic nerve injury, which can cause sensory-motor abnormalities in the lower extremities. If the fracture is not completely broken, it can be recovered, and further exploration of the nerve is needed if necessary. A simple sciatic fracture without other symptoms of vascular or nerve injury does not require surgical treatment, and can be allowed to heal on its own, avoiding sitting and lying flat.
