Flatfoot

Flatfoot is a description of foot position using the medial arch as a reference point.

Causes

• Inherited structural flatfoot
  • May be an insufficiency of ligaments or ligamentous strength
  • May be an articulation genetic mal-placement
  • May be abnormal placement or weakness of the posterior tibial tendon or insertion
• Posterior tibial tendon dysfunction
  • The tendon normally inserts into the medial navicular supporting the talar head and thus supporting the medial arch of the foot
• Tarsal coalition
