| Summary: | Morton's neuroma is a compressive neuropathy resulting in perineural fibrosis rather than a neuroma of the plantar digital nerve. Surgical treatment is indicated for patients with a clear diagnosis of Morton's neuroma and no improvement with nonsurgical treatment. The surgical options include isolated intermetatarsal ligament division, isolated interdigital nerve excision, and interdigital nerve excision with intermetatarsal ligament division, with or without submuscular transposition. This can be performed via dorsal or plantar approach. The open approaches require long incisions and extensive soft-tissue dissection. The purpose of this Technical Note is to describe the surgical details of endoscopic interdigital neurectomy. This is an endoscopic approach involving interdigital nerve excision with intermetatarsal ligament division and submuscular transposition.
