title: Local phenol injection in the treatment of interdigital neuritis of the foot (Morton's neuroma).
abstract: The symptomatic treatment of Civinini-Morton syndrome (interdigital neuritis: IDN) may be performed directly on the nervous trunk involved using orthotic, local pharmacological or surgical methods. Alcoholization with phenol in the percutaneous treatment of IDN has the purpose of provoking a permanent chemical neurolysis, obtaining remission of the neuritic pain symptoms. A total of 71 cases were treated by a dorsal approach to the intermetatarsal space using a needle-electrode connected to the electro-stimulator. Once the nervous trunk with a reproduction of the paresthesia to the fingers was localized, 2.5 ml of phenol at 5% water solution was injected, immediately followed by local anesthetic with a postsurgical analgesic purpose. Mean follow-up was 36 +/- 8 months. The patients were evaluated by visual analogue scale for pain (VAS). Alcoholization of the common interdigital nerve proved to be effective in treating pain in 80.3% of cases (57/71). Treatment must be considered a percutaneous mini-invasive surgical procedure. The results are better than those reported in the literature with conservative and infiltrative treatment and they appear to be comparable today with those obtained when surgical treatment was used, with no complications occurring.
