Animal Models of Disc Degeneration Based on Transgenic and Stress Methods

Dura puncture is one of the most frequent complications even if many attentions are given during the procedure. Particularly in the prone position, the CSF will not dribble due to gravity so it is difficult to notice the dura puncture by CSF leakage. We could not recognize the dura puncture in this case because of doing a blind epidural block in the prone position. When dura puncture occurs, the risk of PDPH is approximately 50% [4].
