Lead through needle technique for placing spinal cord stimulator leads: a novel alternative to the loss of resistance technique

The loss of resistance (LOR) technique has been the traditional technique used to place the percutaneous spinal cord stimulator (SCS) leads into the epidural space under fluoroscopic guidance. The LOR technique was developed long before the use of fluoroscopy in guiding the placement. The technique depends on sudden LOR once the needle tip passes through the ligamentum flavum [1,2].
