title: [Study on the needling depth of lumbar Jiaji (Ex-B2) points with CT imaging location].
abstract: OBJECTIVE
  To study on safe depth and angle of needling lumbar Jiaji (Ex-B2) for treatment of prolapse of lumbar intervertebral disc.
  
  
  METHODS
  CT technique was used for scanning investigation on the depth and angle of needling lumbar Jiaji (Ex-B2).
  
  
  RESULTS
  When the acupuncture needle or puncture needle was inserted at an angle of 20-30 degrees to the sagittal plane of the human body, the tip of needle could reached to extradural posterior space of the depth of lumbar Jiaji points (being the best inserting depth), in which catgut or medicine could be placed.
  
  
  CONCLUSIONS
  Acupuncture or catgut stimulating the extradural posterior space at the depth of lumbar Jiaji is superior to the traditional needling method in treatment of prolapse of lumbar intervertebral disc.
