Endocsopic Decompression of Intermetatarsal Nerve (EDIN) for the Treatment of Morton’s Entrapment— Multicenter Retrospective Review

Background: The authors present the results of a four surgeon, multicenter study of endoscopic decompression for the treatment of Civinini-Morton's entrapment of 193 interspaces.Methods: A retrospective review of 193 interspaces, which were decompressed by four different surgeons.Results: The overall success rate was high, with 92% of patients reporting a good or fair outcome.Higher success rates were reported in the 3rd interspace decompression group (95%) compared to the 2nd interspace decompression group (85%).Complications reported were minimal, with only seven cases requiring a revision with traditional neurectomy.No revisions were required in the 3rd interspace decompression group.Five of the revisions were in the 2nd interspace decompression group, with the remaining two revisions in the combined 2nd/3rd interspace decompression group.Conclusions: Endoscopic decompression for the treatment of Civinnini-Morton's entrapment is a safe and efficacious method of treatment of this nerve entrapment, with very low complication rates and rapid return to normal activity.
