Abstract

A case of cauda equina entrapment in the vertical lamina burst fracture of the second lumbar vertebra is reported. The patient was a 48-year-old male. He was involved in a motor vehicle accident and sustained a Denis Type B burst fracture of the second lumbar vertebra. CT scan demonstrated a vertical lamina fracture. The patient underwent posterior spinal canal exploration and spinal instrumentation. At operation, a dural tear was found, and cauda equina rootlets were entrapped between the lamina fracture fragments. Neural elements were extracted and replaced within the dural sac, and the dural tear was repaired. The fracture was stabilized in the posterior direction with a pedicle screw and rod system. Ten months postoperatively, the patient experienced a slight bowel-bladder dysfunction. Motor examination showed improvement in the strength of the right leg.
