The epidural needles used for spinal cord stimulation (SCS) leads are typically 14 gauge. This specific gauge is chosen for a few important reasons. First, a 14-gauge needle provides a balance between being large enough to facilitate the insertion of SCS leads while still being narrow enough to minimize trauma to the surrounding tissues during the procedure. This helps in achieving a successful placement of the leads into the epidural space with less risk of complications.

Using a needle that is too large can increase the likelihood of causing significant skin or tissue trauma, potentially leading to a higher risk of infection or other complications. Conversely, using a needle that is too small may make it challenging to adequately insert the leads and could result in procedural difficulties. Thus, the 14-gauge selection serves a crucial role in the effectiveness and safety of the SCS lead placement procedure.
