A flat foot, or pes planus, is a deformity that involves the arch of the foot. Patients will often present with a flattening and collapsing of the arch. This can occur in children and adults. Pes Planus can be caused by overuse of the Posterior Tibialis Tendon, or due to a flexible foot type, obesity or hereditary. Over time arthritis in joints can develop due to the excessive motions and strain through the foot and ankle. Not all patients with flat feet have pain and this problem can be treated conservatively. Not all patients with flat feet need surgery.
There are many ways to surgically correct the flat foot, this depends on where the center of the deformity is located. In most surgical cases, there will be a need to do both tendon work and bone work. In some cases the heel bone needs to be cut and moved or the heel bone may need to be lengthened. In severe cases joints maybe fused.
