Bipolar Radiofrequency Ablation for Neuropathic Pain in a Patient with a Morton Neuroma of Atypical Location

Abstract

Introduction: Morton's Neuroma is a common cause of forefoot pain, often resulting from excessive force and compressive footwear, especially in highly active patients. The treatment typically begins with physical therapy and modifications in activity or footwear, progresses to corticosteroid and alcohol injections, and ultimately may involve surgical management. Bipolar radiofrequency ablation (RFA) is an emerging treatment that might delay or prevent surgery and may be more effective than its monopolar counterpart. The aim of this case report is to highlight bipolar radiofrequency ablation as a potential treatment option for Morton's neuroma (MN). Case Presentation: The author’s present a 70-year-old male with a clinical diagnosis of Morton's neuroma in an unusual location who underwent bipolar RFA on the medial side of the left great toe after conservative therapy proved unsuccessful. Following the procedure, the patient showed substantial improvement both functionally and symptomatically, with a notable reduction in pain by 70% at his 3-week check-up. Conclusion: Radiofrequency ablation is increasingly being recognized as a valuable option in the pain management toolkit for Morton's Neuroma. The benefits of delaying or avoiding surgery are particularly significant for athletes and dancers. Compared to monopolar RFA, bipolar RFA may provide a more effective treatment.
