[Thomas George Morton metatarsalgia].
Plantar interdigital neuroma, also called Morton neuroma, neuralgia, or metatarsalgia, is a perineural fibrosis that induces severe intermittent pain and paresthesia, most frequently between the third and fourth metatarsal heads. This compression syndrome or entrapment neuropathy involves one branch of the common plantar digital nerves. Diagnosis is based essentially on clinical examination. Imaging techniques may be useful in the diagnosis of atypical cases and postoperative recurrences. In most case, conservative treatment (such as orthotic shoes or devices or injections) is successful. When they do not succeed, surgery (neurolysis, neurectomy) may be considered.
