|
Morton's neuroma, also known as interdigital neuroma, is a common cause of forefoot pain. It is a compressive neuropathy of the interdigital nerve, which is compressed by the overlying transverse metatarsal ligament. It is not a true tumor. The symptoms are forefoot pain that radiates into the toes, according to the involved nerve branches. Its histological findings are fibrosis around the nerve, demyelination. The clinical diagnosis can be obtained from a detailed history and physical examination, such as the compressive test. Moreover, ultrasonography and magnetic resonance imaging can also be used. Conservative treatment is the common initial treatment modality for interdigital neuroma. Surgical excision or decompression is indicated after a failure of conservative treatments.
