Hindfoot Alignment of Adult Acquired Flatfoot Deformity: A Comparison of Clinical Assessment and Weightbearing Cone Beam CT Examinations

Adult-acquired flatfoot deformity (AFFD) represents a progressive and complex structural deformity of foot [1]. Although Posterior Tibial Tendon (PTT) dysfunction has historically been recognized as the principal culprit leading to collapse of the medial longitudinal arch (MLA) [2], further soft tissue insufficiency and underlying bony deformities have been implicated in the development of AFFD [3,4]. Equinus contracture, spring ligament, interosseous and deltoid ligament attenuation as well as an increased innate valgus angulation of the subtalar joint can predispose to and eventually lead to subtalar joint eversion and subsequent hindfoot valgus [3,5] .
