The decision for operative or nonoperative treatment of pelvic ring injuries is based on:
Pelvic ring stability is assessed by the type and location of fractures and joint injuries involving the pelvic ring.
Local pain and tenderness can be significant and interfere with sitting. Walking and standing as well as bed bound activities will soon become tolerable.
Displaced lower sacral fractures may compromise sacral plexus neurologic function which should be assessed to exclude the need for surgery. If the patient is neurologically normal and deformity is acceptable, activities can be allowed as tolerated with cushions for sitting.
