This contributes to metatarsophalangeal joint capsulitis syndrome which further debilitates the patient because of pain. Non-operative measures of periodic paring of the lesions and accomodative padding is frequently effective. Surgical intervention is often needed and is aimed at reducing the pathologic forces causing the lesions. This may include elevation of the metatarsal head, reduction of metatarsal length, reduction of retrograde forces from a contracted digit, or a combination of the above. Interdigital lesions are usually secondary to frictional forces from hypertrophic condyles on the medial and lateral surfaces of the joints of neighboring digits.
Medical care is frequently adequate in relieving a patients symptoms.
Surgical intervention is aimed at resecting the appropriate hypertrophic condyles and may be perfomed in the podiatric surgical suite. Interdigital Neuroma's T.G. Morton is credited with the misnomer used to describe this painful pedal neuropathy 18 . The lesion is a benign enlargement of the third common digital branch of the medial plantar nerve located between, and often distal to, the third and fouth metatarsal heads. The region is usually supplied by a communicating branch from the lateral plantar nerve as well 19 . The second interspace is the next most common site for intermetatarsal neuromas, though they may present in any interspace.
