X-rays of the lower spine, hip and pelvis to rule out fractures. Prolonged healing time if usual activities are resumed too soon. Proneness to repeated sacroiliac injury. Unstable or arthritic sacroiliac joint following repeated injury. If this is a first-time injury, proper care and sufficient healing time before resuming activity should prevent permanent disability.
Ligaments have a poor blood supply, and torn ligaments require as much healing time as fractures.
Follow your doctor's instructions. These instructions are supplemental. See Appendix 1 for details. Don't move the person until a litter or spineboard can be obtained for safe transport. Don't allow the person to walk until the diagnosis is confirmed.
