Summary

Progressive Collapsing Foot Deformity (PCFD) is a complex, multiplanar condition characterized by hindfoot valgus, peritalar subluxation, midfoot abduction, and collapse of the medial arch, which may progress to rigid deformity with pain and functional impairment. In advanced stages, subtalar arthrodesis is a well-established surgical option to restore hindfoot alignment and stability.

Subtalar Arthrodesis with Mini/Medial Bone Block (SAMBB) is an evolution of the Grice-Green technique, using an autologous bone graft to achieve stable correction of talocalcaneal alignment and improve joint congruency, with favorable clinical and radiographic outcomes.

This study aims to evaluate the three-dimensional corrective effect of SAMBB using weight-bearing CT (WBCT), focusing on hindfoot alignment and talocalcaneal and talonavicular relationships.
