Varus is a medical term used to denote to the inward angulation of the distal segment of a bone or a joint. It is used as opposed to valgus, which denotes outward angulation. Varus is a Latin term meaning bent inward whereas valgus is a Latin that denotes being bent outward.
Pes varus is an example of a varus deformity. It is characterized by the inward turning of the heel or the inversion of the foot. In contrast, pes valgus is a deformity characterized by the outward turning of the heel or the inversion of the foot.
Another example is the coxa vara, which is a varus deformity involving the hip. The angle between the head and the shaft of the femur is reduced, resulting in a limp.1
Another is genu varum. From the Latin genu meaning knee, this deformity results when the tibia is turned inward with respect to the femur and the result is a bowlegged appearance.
