Recently, a new prognostic classification for foot and ankle Charcot arthropathy (Mansoura Classification) was published. The aim of this study was to evaluate the interobserver and intraobserver reliability of Mansoura classification for foot and ankle Charcot arthropathy.
Mansoura classification for foot and ankle Charcot arthropathy was presented to orthopedic surgeons (raters) who participated at Mansoura International Foot and Ankle Course. Thereafter, twenty cases of foot and ankle Charcot were presented to the raters who were asked to rate each case according to the classification. Three weeks after the initial evaluation, six raters from a single institution repeated the rating of the cases. Both interobserver and intraobserver reliability were assessed using Kappa statistics.
Sixty-one raters completed the evaluation of the twenty cases of foot and ankle Charcot. Their interobserver reliability was moderate (Kappa = 0.5). Intraobserver reliability was excellent for six raters (range, 0.81-0.93). Further analysis of the interobserver reliability of the former six raters who were specialized in foot and ankle surgery showed substantial reliability; Kappa = 0.67.
Mansoura classification for foot and ankle Charcot has acceptable reliability which is comparable to other classifications. It could be promising in evaluating the severity and guiding the management of such cases.

最近，一种针对足踝夏科氏关节病的新的预后分类（曼苏拉分类）已发表。本研究的目的是评估曼苏拉分类在足踝夏科氏关节病中的观察者间和观察者内可靠性。
向参加曼苏拉国际足踝课程的骨科医生（评估者）介绍足踝夏科氏关节病的曼苏拉分类。此后，向评估者展示20例足踝夏科氏病例，要求他们根据该分类对每个病例进行评分。在初次评估三周后，来自单一机构的6名评估者重复对病例进行评分。使用Kappa统计量评估观察者间和观察者内的可靠性。
61名评估者完成了对20例足踝夏科氏病例的评估。他们的观察者间可靠性为中等（Kappa = 0.5）。6名评估者的观察者内可靠性极佳（范围为0.81 - 0.93）。对前6名专门从事足踝外科手术的评估者的观察者间可靠性进行进一步分析，显示出较高的可靠性；Kappa = 0.67。
足踝夏科氏关节病的曼苏拉分类具有可接受的可靠性，与其他分类相当。在评估此类病例的严重程度和指导治疗方面可能很有前景。
