MRI Evaluation of Cervical, Spring, and Interosseous Talocalcaneal Ligament Orientation in Progressive Collapsing Foot Deformity.

ABSTRACT:

Background

Progressive collapsing foot deformity (PCFD) is a complex condition characterized by progressive ligamentous and osseous changes in the hindfoot, midfoot, and forefoot. Although osseous changes at the subtalar and transverse tarsal joints have been well studied, ligamentous anatomy in PCFD is less understood. This study evaluates the cervical, interosseous talocalcaneal, and superomedial fibers of the spring ligament in patients with PCFD vs controls using magnetic resonance imaging (MRI) analysis.

Methods

Nonweightbearing MRI and weightbearing radiographs of 39 patients (23 PCFD, 16 controls) were retrospectively reviewed. MRIs measured the coronal plane orientation of the interosseous talocalcaneal, cervical, and superomedial spring ligaments relative to the sub
