"Group with scan prior to infiltration "
Scan will be conducted by the operator performing the gesture. He will examine the lumbar spine from L3 to S1, in longitudinal and cross sections and determine the best surgical approach. This will be defined by the largest interspinous space or better visibility of the epidural space. The depth of the epidural space will be noted. The selected stage will be marked with a skin pen to facilitate its location thereafter
