Corrective Osteotomy of Metatarsal Bone for Surgical Treatment of Morton's Neuroma.

Purpose: The purpose of this report is to investigate the clinical and radiological results of corrective osteotomy of the 3rd metatarsal bone for shortening and dorsal displacement without exposure around neuroma. Materials and Methods: Twelve cases of patients who underwent corrective osteotomy of metatarsal bone for a Morton's neuroma from November 2013 to September 2014 were retrospectively reviewed. Corrective osteotomy was performed through a dorsal approach at the 3rd metatarsal bone base and distal metatarsal bone was displaced dorsally and proximally. Preoperative and postoperative pain assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and radiographs were evaluated. Results: The mean age of patients was 41.4 years, and the mean follow-up period was 10.7 months. AOFAS score improved from 52 preoperatively to 90 postoperatively. The 3rd metatarsal bone was shortened by an average of 3.39 mm and elevated by 2.38 mm. Conclusion: Corrective osteotomy of metatarsal bone can be regarded as a new surgical option for Morton's neuroma without exposure around neuroma. [ABSTRACT FROM AUTHOR]
