Flatfoot Deformities

Pes planus is also known as flat foot

  • Loss of the medial longitudinal arch of the foot
  • Heel valgus deformity
  • Medial talar prominence

The deformity is usually asymptomatic and resolves spontaneously in the first decade of life, or occasionally progresses into a painful rigid form which causes significant disability.

It has 2 forms. When the arch of the foot is intact on heel elevation and non-bearing but disappears on full standing on the foot, it is termed FLEXIBLE FLATFOOT while RIGID FLATFOOT is when the arch is not present in both heel elevation and weight bearing.

The most common etiology of the adult acquitted flatfoot is Posterior Tibial Tendon Dysfunction (PTTD)

Surgical Procedures:

Flatfoot correction (flexible deformity): osteotomy with tendon transfer

A flatfoot deformity that remains flexible can be corrected through a series of bony osteotomies and tendon transfers to centre the heel, return the Achilles tendon to it’s normal line of pull of the Achilles tendon, relieve impingement and inflammatory pain, as well as restore the medial arch.

Flatfoot correction(rigid deformity):

Triple Fusion
