Abstract

Background: Spinopelvic dissociation is considered a very complex orthopedic injury. The presence of intrapelvic displacement and L5 traumatic sacralization makes our report a very rare presentation.

The case: A 60-year-old gentleman presented with a rare traumatic fracture dislocation of the lumbosacral complex with intrapelvic displacement and L5 sacralization; treated with two surgical stages: 1) pelvic external fixation and posterior pelvic tension band plate, and 2) T10 to pelvis posterior fixation.

Conclusion: Intrapelvic displacement of S1 in the presence of spinopelvic dissociation is very rare injury that requires high mechanism of injury, surgical management is important to improve functional outcome.

Keywords: Sacral fractures; Spinopelvic dissociation; Spinopelvic fixation; Traumatic L5 sacralization.
