Case: We presented a case of extension-distraction spine injury at lumbosacral junction in a patient with fused spine concomitant with a lumbosacral transitional vertebra. Detail of an exceedingly rare case of traumatic lumbosacral hyperextension-distraction fracture in the individual was described and reviewed.

Conclusion: Although the occurrence of extension-distraction spine injury at lumbosacral junction is extremely rare, it can occur in some circumstances. Application of damage control spine concept including early definitive stabilization of spine fractures and minimally invasive spine surgery can give satisfactory outcomes in the polytraumatized patient.
