flat foot


A common–20-30% of the population–complaint, which affects many age groups, but true flat feet (as defined by orthopaedists) are uncommon. Parents may incorrectly perceive flattening of the foot when a child first walks. True flat foot is characterised by laxity of the ligaments resulting in collapse of the foot with valgus on the hindfoot, and eversion or pronation of the forefoot.

flat foot

A valgus deformity of > 10% requires therapy; often a shoe will suffice as therapy. Flat foot grading is based on disability, ranging from mere strain or tenderness to osseous rigidity. The peroneal spastic flat feet variant is commonly due to abnormal coalescence between 2 or more tarsal bones, often at the calcaneocuboid, calcaneonavicular, and talocalcaneal bars

Flat foot—acquired types

Ligamentous Due to tendino-ligamentous trauma

Muscular Due to poor control or incoordination–poliomyelitis or cerebral palsy

Osseous Due to trauma or degeneration

Postural Due to internal tibial torsion as occurs in obesity, muscle fatigue, faulty footwear and less than facile footwork, and arthritis

Synonyms Fallen arches, pes planus
