Abstract

Traumatic lumbosacral dissociation is a unique, but well-documented, phenomenon that generally stems from high-energy impact injuries to the lower lumbar spine. Patients typically present with complicated and multisystem injuries with wide-ranging neurological deficits below the level of trauma. This presents stark challenges regarding the diagnosis, management, and surgical correction technique utilized. In this study, we present the case of a 21-year-old, morbidly obese, male patient that presented after a traumatic motor vehicle accident with L5-S1 lumbosacroiliac dissociation, cauda equina syndrome, and left lower extremity monoplegia. The degree of disruption warranted a 360° approach, we opted for an anterior lumbar interbody fusion followed by a posterior, lumbar interbody, short segment fusion. We review the case and relevant literature of similar lumbosacral dissociation studies with their management options and outcomes. Due to the rare nature of these devastating injuries, there remains wide variability in their management, with a combination of open anterior and posterior approaches resulting in variable long-term outcomes. The management of these rare injuries will require appropriate consideration of the patient’s unique etiology, coexisting injuries, and radiological imaging in deciding surgical stabilization techniques.
