Abstract

Background: Progressive collapsing foot deformity (PCFD) represents a multifaceted three-dimensional condition. However, there has been limited discussion regarding how the morphology of each bone affects PCFD.

Purpose: To determine morphological differences within each bone of the foot and ankle in females affected by PCFD compared to asymptomatic controls.

Study design: Comparative cross-sectional study.

Methods: We hypothesized the medial column bones would exhibit the most substantial shape differences between groups. We developed multiple statistical shape models (SSMs) to analyze the 3D shape of the distal tibia, distal fibula, talus, calcaneus, navicular, cuboid, cuneiforms, and metatarsals. We quantified and compared results between 23 female PCFD patients and 23 asymptomatic females.

Results: SSM analyses revealed significant modes of variation across several bones. Notably, the fibula showed reduced fibular tip height in PCFD patients. The talus exhibited decreased lateral and posterior processes and an inferior, adducted talar head shift. The calcaneus had a narrowed posterior facet and anteriorly shifted anterior-medial facet. In PCFD patients, the navicular tuberosity was displaced toward the body with medial-inferior articular defects. The cuboid showed increased prominence of the tuberosity and beak.

Conclusion: These SSM results provide novel characterization of the 3D shape of bones from tibia to metatarsals in PCFD and asymptomatic females. Patients with PCFD exhibited distinct 3D shape differences in the distal fibula, talus, calcaneus, navicular, and cuboid, suggesting that PCFD is primarily characterized by deformities of the hindfoot bones.

描述女性进行性塌陷足畸形和无症状对照之间的三维骨形态解剖差异。
背景:进行性塌陷足畸形(PCFD)是一种多面三维疾病。然而,关于各骨形态如何影响PCFD的讨论有限。目的:确定与无症状对照组相比,女性PCFD患者足部和踝关节各骨的形态学差异。研究设计:比较横断面研究。方法:我们假设两组之间的内侧柱骨表现出最显著的形状差异。我们开发了多个统计形状模型(SSMs)来分析胫骨远端、腓骨远端、距骨、跟骨、舟骨、长方体、楔形骨和跖骨的三维形状。我们量化并比较了23名女性PCFD患者和23名无症状女性的结果。结果:SSM分析揭示了几块骨头的显著变异模式。值得注意的是,PCFD患者的腓骨显示腓骨尖端高度降低。距骨表现为外侧和后侧突减少,距骨下内收头移位。跟骨后侧关节面狭窄,前内侧关节面前移位。在PCFD患者中,舟状结节向身体移位并伴有中-下关节缺损。长方体显示结节和喙的突出。结论:这些SSM结果提供了PCFD和无症状女性从胫骨到跖骨的三维形状的新特征。PCFD患者在腓骨远端、距骨、跟骨、舟骨和长方体表现出明显的三维形状差异,表明PCFD主要以后足骨畸形为特征。
