mandatory as post-traumatic ligamentous insufficiency would lead to abnormal motion. Operative treatment managed to
produce a solid arthrodesis and restore stability of the lumbosacral junction. Follow-up revealed excellent results. This
study reports a rare injury of the lumbosacral junction, and the literature concerning this unusual condition is extensively
