摘要
Between 1990 and 1996, 15 patients with thoracolumbar spine fracture complicated by simple conusmedullaris injury were admitted. All patients were Injured by falling from height (mean, o meters). Clinical symp-toms indicated hypoesthesia or anesthesia of S3-5 sensory region,dysporia and urinary dysfunction. but normal sensation and motion of the bilateral lower extremities. Waston-Jones classified the spinal cord and nerve root injury following thoracolumbar spine fracture into three types. According to our observations, it should be classfied into five types: 1) concussion of the conus medullaris; 2) simple incomplete injury of the conus medullaris; 3) simplecomplete injury of the conus medullaris; 4) spinal cord transection and partial nerve root injury; 5) spinal cordtransection and entire nerve root injury.
