Peripheral Nerve Stimulation for the Management of Chronic Pain Syndrome: A Case Study of Complex Regional Pain Syndrome Posttrauma and After Surgery in the Leg.

BACKGROUND: Complex regional pain syndrome (CRPS) is a very challenging condition to treat. We present a case resistant to conservative management that was treated by peripheral nerve stimulation (PNS). CASE REPORT: Our case study highlights the efficacy of PNS in the management of chronic pain syndromes, specifically CRPS, following major trauma and surgical intervention. Our case report involves a patient experiencing debilitating postoperative pain who underwent PNS treatment targeting the right infrapatellar branch of the saphenous nerve and posterior tibial nerve. Remarkably, the patient demonstrated a significant improvement in subjective pain levels with a reduction of approximately 75%, as well as enhanced functional capacity, compared to before the intervention. CONCLUSIONS: Our case underscores the potential of PNS as a viable therapeutic option for individuals suffering from CRPS and other postsurgical chronic pain syndromes.
