《2020AOFAS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

摘要:

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 flat-foot 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。

Abstract:

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