ETIOLOGY OF SYMPTOMATIC RECURRENT INTERDIGITAL NEUROMAS

Morton's neuroma is a common disease entity of the foot that is often treated with surgical resection. A complication of neuroma resection i s recurrence of symptoms as a result of the formation of an amputation neuroma. The authors offer an anatomical and biomechanical explanatio n for the location of symptomatic amputation neuromas. The neuromas ar e found on the plantar surface proximal to the condyles of the metatar sal and medial to the interspace where the nerve is resected. The theo ry is based on intraoperative observations during surgery for recurren t neuromas and on cadaver dissections and offers a method based on thi s theory to reduce the number of recurrences.
