Abstract

This article discusses the modern method of treatment of transverse flat feet using carbon nanostructured implants. The characteristic features of the installation, recovery period, features of consolidation, cosmetic and functional results are analyzed. Based on the research, the disadvantages of the method, its characteristics and features were identified, and the results were compared with the data stated by the implant manufacturer
