Measurement of the spinal canal by diagnostic ultrasound.

A method is described of measuring the lumbar spinal canal by pulsed echo ultrasound. It is simple, safe and has a high degree of accuracy. The lumbar canal has been measured in over 800 subjects including 100 mining recruits and fifty nurses between the ages of fifteen and eighteen years. Ultrasound can demonstrate the degree and extent of bony stenosis. It may have value in preventive medicine, identifying the subject at risk.
