Persistent or recurrent interdigital neuromas.

Abstract

Recurrent or persistent symptoms following surgical neurectomy for an interdigital neuroma are quite common, because of incorrect initial diagnosis, true neuroma formation, nerve stump adhesions, accessory nerve branches, or an adjacent web space neuroma. The clinical presentation of a recurrent neuroma is similar to the initial presentation. Recurrent symptoms usually occur within the first 12 months after surgery. The physical examination coupled with diagnostic nerve blocks is critical for diagnosis. Conservative therapy, although not particularly effective in treating true recurrent neuromas, may help to alleviate pain. With proper isolation of the instigating neuroma, revision surgical excision can be effective.
