Abstract
Pes planus is the flattening or lack of the medial longitudinal arch of the foot, resulting in an abnormal gait pattern. The flexible flatfoot may present with pain, tightness of the Achilles tendon, swelling over the posterior tibial tendon, and difficulty ambulating or performing a single heel rise. The “too many toes sign,” where 3+ toes are visible laterally when viewing the patient posteriorly, may be observed. The rigid flatfoot is a spastic deformity with restricted ROM of the subtler joint and is associated with tarsal coalition. When symptomatic, workup should include weight-bearing x-rays. Treatment ranges from conservative to surgical with the latter saved only for those that have intractable pain, have interference in their activities of daily living, and have failed all other treatments.
