Wukich DK, Raspovic KM, Liu GT, et al. - This study was undertaken to investigate the intra- and inter-reader reliability of the 2 Charcot neuroarthropathy classifications (Sanders/Frykberg and Brodsky/Trepman), as well as Eichenholtz staging. Researchers assumed that the inter-reader reliability, with respect to these 3 classification systems, would be moderate at best. Among physicians, the classification systems of Charcot neuroarthropathy are an important tool for communication. The results of this study demonstrated that the Sanders/Frykberg classification showed the best inter-reader performance. As per the findings, the Trepman/Brodsky classification showed good to excellent reliability as well. It was shown that the intraclass correlation coefficient of the Eichenholtz classification was moderate to good.
