An Exploratory Statistical Shape Modeling Analysis of Three-Dimensional Foot Alignment in Female Patients With Progressive Collapsing Foot Deformity.

Puntos clave

The central aim is to analyze three-dimensional foot alignment variations in female patients with progressive collapsing foot deformity (PCFD).
Utilized multi-domain statistical shape modeling (SSM) from SW-CT imaging.
Assessed alignment deformities specifically in foot joints.
Evaluated coordinated changes in multiple foot joints.
Subtalar and Chopart joints exhibited coordinated changes in alignment.
Lisfranc joint showed opposing alignment variations.
Talonavicular joint displayed a medial spreading pattern.

Resumen

The application of a multi-domain SSM from SW-CT to evaluate alignment deformities in patients with PCFD represents a new and novel approach to understanding the pathophysiology of this condition. In PCFD, the subtalar and Chopart joints showed coordinated changes, whereas the Lisfranc joint demonstrated variation in the opposite direction. Also, the talonavicular joint spreads out medially in a fan-like direction in PCFD.
