We studied 366 feet in 313 patients who underwent surgical treatment for a primary interdigital neuroma through a dorsal web-splitting incision. Three hundred five feet in 259 patients were available for follow up, which averaged 5.9 years (range: 2.8 to 13); 45.2% of these patients were completely satisfied, 33.8% were satisfied with minor reservations, 9.2% were satisfied with major reservations, and 11.8% were dissatisfied after the surgical procedure. Patient satisfaction was directly related to the size of the neuroma found at the time of operation. Bilateral procedures were associated with a higher rate of dissatisfaction. The third web space accounted for 91% of the neuromas.
