The arch of the foot usually develops between the age of 3 and 5 years. Flatfoot, also known as fallen arches or pesplanus, is a deformity in which the arch that runs along the sole of the foot is not formed (in children) or collapses to the ground (in adults due to various foot problems). Flatfoot can be rigid or flexible. Flexible flatfoot usually resolves without any treatment unless pain is involved, while rigid flatfoot usually requires intervention.
Pediatric flat foot is a common condition that can run in families. It is often caused by abnormalities between joints while your baby is developing in your womb. A rare condition called tarsal coalition can also cause flatfoot, where two or more bones of the foot join together abnormally causing stiff and painful flat feet. In adults, flat foot can develop from stretched, damaged, torn or inflamed tendons, fracture or dislocation, rheumatoid arthritis or nerve problems.
Flatfoot deformity may have one or more of the following signs and symptoms:
The doctor will perform a physical examination of the affected foot and observe it while standing, on tip-toe and sitting positions. The wearing on the shoes may also be observed. X-rays, computed tomography (CT) scan and magnetic resonance imaging (MRI) may be ordered.
If there is no pain, apart from regular monitoring, no treatment is required. To relieve symptoms, the following non-surgical treatments may be suggested:
If conservative treatment options fail to relieve flatfoot symptoms, surgery may be necessary. Various procedures may be performed including cutting and realigning of bone, tendon transfers, tendon lengthening and bone fusion.
