Four patients with lumbosacral fracture-dislocation are presented. The common mechanism of injury was hyperflexion with compression. A rotational element may be implicated in single facet dislocation. Although lumbosacral fracture-dislocations can be managed conservatively, the best method of treatment is open reduction and bone grafting as soon after injury as possible. Only this will ensure complete correction of the deformity and prevent later deterioration.
