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.
Undisplaced lower sacral fractures will not require reduction but a donut cushion will relieve pain during sitting.
