《2020 AOFAS进行性塌陷足畸形分类与命名共识》的解读

Interpretation of classification and nomenclature for progressive collapsing foot deformity by AOFAS in 2020

近来,基于胫后肌腱功能不全(posterior tibial tendon dysfunction,PTTD)对成人获得性平足畸形(adult acquired flatfoot deformity,AAFD)的传统分类方式受到了质疑。2020年发布的专家共识提出一种新的分类方式,并建议使用进行性塌陷足畸形(progressive collapsing foot deformity,PCFD)这一命名取代之前的PTTD。新版分类系统基于柔韧性、畸形的位置和类型对PCFD分类,能够更全面地阐明这类畸形状态。本文将对新版分类共识进行解读。

Recently,the traditional classification of adult acquired flatfoot deformity(AAFD)based on posterior tibial tendon dysfunction(PTTD)has been questioned.The expert consensus published in 2020 proposed a new classification and recommended that the progressive collapsing foot deformity(PCFD)be used instead of the previous PTTD.The new classification system classifies PCFD based on flexibility,location and type of deformity,which can more comprehensively elucidate the status of such deformity.This paper will interpret the newclassification consensus.
