IntroductionThe field of neuromodulation continues to grow, especially in the area of pain management. Percutaneous nerve field stimulation continues to gain significant popularity for chronic, focal, and intractable neuropathic pain.Materials And MethodsTuohy needles have been traditionally used as the instrument of choice for subcutaneous implantation of peripheral field stimulators. The ON-Q® Tunneling System (Braun Melsungen AG, Melsungen, Germany) provides an adaptable option for subcutaneous implantation of electrodes, with a variety of lengths and gauges available. This system uses a disposable blunt needle and a peel-away sheath and is firm but malleable. Gentle curves can be applied to the stylet prior to implantation. The blunt, malleable nature of the needle and the soft Silastic sheath allow for applications in areas with greater curvature, such as the face, and ensure a subcutaneous placement.ConclusionsThe great adaptability of this system allows for implantation of electrodes subcutaneously with efficacy and ease. Here we present a technical note on the use of this system for subcutaneous implantation of peripheral nerve field stimulators.© 2014 International Neuromodulation Society.
