The outcome after using two different approaches for excision of Morton＇s neuroma

Background The choice for the surgical approach of interdigital neuroma in the foot is controversial.Plantar approach can leave a painful scar on weight bearing area; hence, some prefer dorsal approach.The aim of the current study was to measure the outcome of interdigital （Morton＇s） neurectomy performed by a single surgeon using dorsal and plantar approaches.Methods A retrospective review of the patient records of one orthopaedic foot and ankle surgeon identified thirty-six patients （42 feet） who had been treated operatively for a primary, persistently painful interdigital neuroma.The mean follow-up was 18 months.Pain, weight bearing, wound problems and rehabilitation period were studied.Results The duration to full weight bearing, return to work, driving and recreational activities were at least one week shorter in the dorsal group.The overall satisfaction for surgery was rated as excellent or good in 85% of the thirty six patients.Scar problems were more troublesome and common in the plantar group.There was residual numbness noticed in twenty feet, the pattern of numbness was quite variable and it was bothersome in only seven feet.There was one recurrence in the plantar group.Conclusions Resection of a symptomatic interdigital neuroma through a dorsal or a plantar approach can result in a good outcome.Dorsal approach, however, is associated with better rehabilitation and less scar problems.
