进行性塌陷足畸形（PCFD）的特征是趾周骨和关节进行性半脱位。二维传统 X 光片无法以足够的细节可视化趾周骨骼和关节来描述复杂的三维 (3D) 形态。本研究的目的是使用负重计算机断层扫描 (WBCT) 扫描分析距小腿、距下关节和 Chopart 关节内六个关节关系的关节覆盖范围。将 10 名具有柔性 PCFD 的个体和 10 名具有刚性 PCFD 的个体与 27 名无症状健康个体进行比较。三个最相关的发现是：I) 距下关节的前内侧小面对于刚性畸形患者的覆盖范围减少最大，II) 距舟重叠的增加与胫距、前内侧距下关节、距舟关节的覆盖范围的减少中度相关，以及 III) 跟骰关节缺乏影像学值来充分量化对准和覆盖范围。总之，当 PCFD 患者与健康个体进行比较时，整个后足和中足各个关节区域的覆盖面积存在显着差异。确定了与临床感兴趣的关节覆盖区域相关的相关放射学测量，可能有助于在临床实践中更好地量化 PCFD。
Progressive collapsing foot deformity (PCFD) is characterized by a progressive subluxation of the peritalar bones and joints. Two-dimensional conventional radiographs are limited in their ability to visualize the peritalar bones and joints with adequate detail to describe the complex three-dimensional (3D) morphology. The aim of this study was to analyze the joint coverage of the six articular relationships within the talocrural, subtalar, and Chopart joints using weightbearing computed tomography (WBCT) scans. Ten individuals with flexible and ten individuals with rigid PCFD were compared to twenty-seven asymptomatic healthy individuals. The three most relevant findings are: I) the anterior-medial facet of the subtalar joint contains the greatest reduction in coverage for patients with a rigid deformity, II) an increase in talonavicular overlap moderately correlated with a decreased coverage in the: tibiotalar, anterior-medial subtalar, talonavicular joints, and III) the calcaneocuboid joint lacks radiographic values to adequately quantify alignment and coverage. To conclude, there were significant differences in coverage area of various articulating regions throughout the hind- and midfoot when comparing PCFD patients to healthy individuals. Relevant radiographic measures correlating to articular coverage areas of clinical interest were identified, possibly helping to better quantify PCFD in clinical practice.
