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

Key Points

• 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.
