Thoracic fracture-dislocations without spinal cord injury: a case report and literature review.

Severe fracture-dislocation of the thoracic spine without neurological deficit is rare. Both translational and rotational deformity of the midthoracic spine makes transection of the cord almost inevitable due to the confined dimensions of the cord and spinal canal. Even though associated fractures of posterior elements are frequently seen, they seldom result in neural sparing. The case of a 24-year-old man who sustained a severe rotational fracture-dislocation of T9/T10 with considerable anterolateral displacement is reported. Due to a fractured left pedicle and a right-sided vertical fracture through the posterior aspect of the vertebral body, alignment of the posterior elements in the spinal canal was maintained and there was no neurological deficit. The patient was operatively treated with posterior segmental instrumentation, and was completely asymptomatic at follow-up 5 years later.
