Tuohy needle is then percutaneously placed in the lumbar subdural space, similar to a standard lumbar drain catheter insertion. An Ad-Tech lead is then passed and advanced under fluoroscopic guidance. The lead is tested for stimulation and degree of pain relief. The lead is anchored in place for post-operative percutaneous SCS trial (≤14 days). Figure of eight suture using 2.0 Silk is used to close the skin.
