Traumatic sacralization of L5 vertebra with severe extension type spinopelvic dissociation: A case report

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.

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.

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.
