Complex Lumbosacral Fracture-Dislocation with Sacral Fracture: Report of a Case and Review of the Literature
Abstract Purpose: Traumatic lumbosacral fracture-dislocation is a very rare pattern of injury. We report a patient who has been suffered from a traffic accident and resulted in concomitant severe injuries: complex lumbosacral fracture-dislocation with pelvic ring disruption and vertical shear sacral fracture; Pneumothorax. Methods: She was transferred to the emergency department at the local provincial hospital and treated with the pelvic external fixation and closed drainage of thoracic cavity. For the further therapy, she was transferred to our hospital. The neurological examination revealed incomplete S1 paraplegia in the right lower extremity, the left lower extremity was normal, and rectal tone was existed. Standard x-rays and computed tomography revealed L5-S1 fracture-dislocation and fractures of the L5 transverse processes. Results: She was treated with S1 laminectomy and L5-S1 interbody fusion using lumbo-iliac internal fixation. Conclusions: Available literatures on lumbosacral fracture-dislocation were also reviewed which illustrate the pathogenic, clinical, radiological and therapeutic aspects of lumbosacral fracture dislocation.
