Pes Planus / Flat Foot

– Discussion: – loss of normal medial longitudinal arch leads to pes planus, which can be flexible or rigid; – may arise as a consequence of hyper-pronation or from increased eversion of the subtalar joint; – hence, the calcaneus lies in valgus and external rotation relative to the talus; – associated midfoot sag may be … Read more
