Postural Deformities

Flat feet

Flat feet (also called pes planus or fallen arches) is a postural deformity in which thearches of the foot collapse, with the entiresole of the foot coming into complete or near-complete contact with the ground. Some individuals (an estimated 20–30% of the general population) have an arch that simply never develops in one foot (unilaterally) or both feet (bilaterally).

There is a functional relationship between the structure of the arch of the foot and the biomechanics of the lower leg. The arch provides an elastic, springy connection between the forefoot and the hind foot. This association safeguards so that a majority of the forces incurred during weight bearing of the foot can be dissipated before the force reaches the long bones of the leg and thigh.

Bow legs

Genu varum (also called bow-leggedness,bandiness, bandy-leg, and tibia vara), is a physical deformity marked by (outward) bowing of the lower leg in relation to the thigh, giving the appearance of an archer's bow. Usually medial angulation of both femur andtibia is involved.
