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.
莫顿神经瘤是一种压迫性神经病变，会导致神经周围纤维化，而非足底趾神经的神经瘤。对于明确诊断为莫顿神经瘤且非手术治疗无效的患者，建议进行手术治疗。手术选择包括单纯跖间韧带切断术、单纯趾间神经切除术、趾间神经切除术联合跖间韧带切断术，可伴或不伴肌下转位。可通过背侧或足底入路进行。开放手术需要较长切口和广泛的软组织分离。本技术说明的目的是描述内镜下趾间神经切除术的手术细节。这是一种内镜手术方法，包括趾间神经切除术、跖间韧带切断术和肌下转位。
