摘要/Abstract

摘要： 目的对Karger脂肪垫(Karger fat pad, KFP)的影像形态特征进行分类，并探讨其与后踝撞击综合征(posterior ankle impingement syndrome, PAIS)的关系。方法对2018年8月至2021年8月间的194例中国人的踝关节磁共振成像(MRI)扫描进行观察。在T1加权MRI上测量与KFP相关的FHL长度、KFP高度、与KFP相关的跟腱长度、距后三角骨长度、胫骨后下突长度、KFP与胫骨的最短水平距离、KFP矢状面面积、三角骨-跟骨-胫骨角等解剖参数。结果本研究共纳入194例三角籽骨综合征患者，其中对照106例(无PAIS)， PAIS患者88例。根据KFP的形状、长度、高度和矢状面积将其分为3种类型：Ⅰ型（三角形）、Ⅱ型（长梯形）、Ⅲ型（短梯形）。3种KFP类型中，PAIS中Ⅲ型(72, 81.8%)最多，对照组中Ⅰ型(43, 40.6%)和Ⅱ型(55, 51.9%)所占比例较大。结论 PAIS患者与非PAIS患者的KFP形态存在显著差异。KFP的变化在PAIS的进展中是至关重要的，正确理解不同类型的KFP有助于研究PAIS的特点，可以为临床诊断早期PAIS提供一定依据。

Abstract: Objective To classify the imaging morphologic features of the Karger fat pad (KFP) and to investigate its relationship with posterior ankle impingement syndrome (PAIS). Methods A total of 194 Chinese patients with ankle magnetic resonance imaging (MRI) scans between August 2018 and August 2021 were observed. Anatomical parameters included flexor hallucis longus-related length of KFP, KFP height, achilles-related length of KFP, the length of os trigonum, length of posterior inferior tibial process, the shortest distance between KFP and tibia, KFP sagittal area, and os trigonum-calcaneus-tibia angle were measured in T1-weighted MRI. Results A total of 194 subjects with os trigonum syndrome were enrolled in this study and there were 106 patients without PAIS (control group) and 88 patients with PAIS. KFP was categorized into 3 types based on its shape, length, height and sagittal area: type I (triangular), type II (long trapezoidal), type III (short trapezoidal). Among the three KFP types, Type Ⅲ (72, 81.8%) accounted for the greatest number in PAIS group, while Type Ⅰ (43, 40.6%) and Type Ⅱ (55, 51.9%) accounted for the larger proportion in the control group. Conclusion There is significant difference in the morphology of the KFP between individuals with and without PAIS. It is assumed that the change of KFP is crucial in the progression of PAIS, and a better understanding of different types of KFP is helpful to study the characteristics of PAIS, which can provide certain basis for clinical diagnosis of PAIS in the early stage.
