Diagnosis and treatment of forefoot disorders. Section 3. Morton's intermetatarsal neuroma.

Nerve pathologies are a common cause of forefoot pain and include diverse conditions with similar symptoms. The symptoms are characteristic of sensory nerve disorders and differ from other musculoskeletal conditions. Morton’s intermetatarsal neuroma is a compression neuropathy of the common digital nerve (Fig. 1). It is most commonly seen in the third intermetatarsal space, but it also can be seen in other intermetatarsal spaces (Fig. 2). A neuroma may occur in more than one intermetatarsal space and may be bilateral. Neuromas are more prevalent in adults beginning in the third decade of life, and are more common in females than males (1-7).
