Sacral rods offer a proven method of fixation for posterior instability of the pelvic ring, especially in sacral fractures and SI joint fusions. Their stability has been proven in numerous studies and is often considered the "gold standard" in treatment.

For type C injuries, ventral plate osteosynthesis is performed first, followed by posterior stabilisation, which can be performed in the same session or as a second procedure.

New, sophisticated instrumentation allows for a standardised and simplified application technique.
