Abstract
Dislocation fracture of the lumbosacral spine is a relatively rare lesion. Here we report two cases of this injury in patients with multiple trauma. Case 1 : A 38-year-old man who was injured when a heavy load fell onto his back. Radiographs demonstrated anterior displacement of the fifth vertebra with bilateral facet dislocation and left inferior facet fracture. Four days after the injury, the patient underwent posterior lumbar interbody fusion (PLIF). At the five-month follow-up, the patient was able to walk with a crutch, but right coxalgia persisted. Case 2 : A 39-year-old man who fell from a height of about 8 m. Radiographs showed bilateral-facet fracture dislocation. A posterior lumbar interbody fusion was performed on the day after injury. At the one-year follow-up point, the patient was able to walk alone and had returned to work at a construction site. For dislocation fracture of the lumbosacral spine, surgical treatment for reduction, stabilization, and interbody fusion has been recommended by several authors. We performed PLIF for two such cases, and obtained good short-term results.
