How do we target specific nerves?


How do we target specific nerves?

Answer:
When managing chronic pain, the clinician must identify the associated sensory nerve. Then the clinician must place the radiofrequency nerve ablation probe close enough to the nerve to create sufficient thermal damage to stop conduction. Current devices provide the clinician with a mechanism to assess the position of the probe relative to the nerve by measuring impedance. Impedance is the resistance of the tissues between the tip of the probe and the target nerve. The greater the distance between the nerve and the probe, the greater the impedance will be. The ability to measure impedance between the probe and the nerve represents a significant advance in the treatment of plantar fasciitis with radiofrequency nerve ablation and allows the clinician to move the procedure from the operating room to the pain clinic.
