Abstract:
Morton's neuroma is a prevalent cause of forefoot pain, predominantly affecting middle-aged women and typically occurring in the third intermetatarsal space. The precise pathological mechanism remains unclear, with the chronic trauma theory being the most widely accepted explanation. Patients commonly present with localized pain, paresthesia, or tingling at the level of the metatarsophalangeal joint. Clinical diagnosis is generally accurate, although no definitive gold standard for treatment exists. Non-surgical management includes both non-invasive and invasive options, such as ultrasound-guided radiofrequency ablation and type I collagen injections. Neurotomy represents the traditional surgical intervention. Recent advancements in treatment include ultrasound-assisted ethanol and steroid injections, the utilization of fluorescence microscopy, electroneurography, percutaneous electrode stimulation techniques, and neurolysis, with or without dorsal nerve displacement. Additional procedures such as the release of the deep transverse metatarsal ligament, metatarsal osteotomy, and targeted muscle nerve reinnervation following nerve transection or neurectomy are aimed at enhancing diagnostic precision and therapeutic efficacy, thereby improving the overall clinical outcomes for patients with this condition.
