What are the complications of sacral fracture?

If the sacral fracture is only a minor fracture or the sacral fracture is located in the sacral ala, there is no damage to the sacral foramen and sacral canal, and there is no neurologic impairment, the patient has no obvious complications after the sacral fracture has healed, or only mild sacrococcygeal discomfort can be obtained after conservative treatment. If the sacral fracture is located in the sacral foramen and sacral canal, causing nerve root or dural sac injury, showing cauda equina nerve injury, it may cause nerve dysfunction of the patient's lower limbs, sensory dysfunction of the perineum and defecation dysfunction, etc. Even after surgical treatment, nerve function may not be completely restored, and some nerve dysfunction will remain.
