Interdigital neuroma: intermuscular neuroma transposition compared with resection.
This prospective, randomized study compares the treatment of an interdigital neuroma (IDN) by the standard resection operation with a technique in which the IDN is transposed into the inter-muscular space between the adductor hallucis and the interossei muscles after division of the digital nerves distal to the IDN. The resection group contained 22 patients and 22 neuromas and the transposition group contained 22 patients and 23 neuromas. An interviewer, blinded as to the operative technique used, telephoned each patient preoperatively, and at 1 month, 3 months, 6 months, 12 months, and 36-48 months postoperatively. The interviewer recorded the patient's reported pain level on a numerical rating scale of 0 to 100. In the resection group the average pain level was slightly lower through the first 6 month period, but at the 12 month review the resection group had a slightly higher average pain level . At the 36-48 month survey the resection group again reported a greater average pain level and fewer asymptomatic patients. It was concluded that it is unnecessary to excise the IDN to obtain excellent relief of pain. It was also concluded that transposition of the IDN into an intermuscular position between the adductor hallucis and the interossei muscles produced significantly better long term results than did the standard resection operation.
