Supplement


Valgus is a medical term used to refer to the outward angulation of the distal segment of a bone or joint. It comes from the Latin term meaning bent outward. It should not be confused with the other related term varus which pertains to the inward deviation of the distal bone towards the midline.

An example of valgus deformities is pes valgus, which involves the foot. Pes valgus (from Latin pes meaning foot) is an eversion of the foot at the talocalcaneal or subtalar joint. It is usually combined with a breaking down of the plantar arch. Another is the talipes valgus (from Latin talus meaning ankle and pes meaning foot), which is the outward turning of the heel. This deformity of the ankle results in a clubfoot wherein the person walks on the inner part. Another form of vagus deformity is the cubitus valgus. Cubitus valgus (from Latin cubitus pertaining to elbow) is the medical term for a turned-in elbow. Coxa valga (from Latin coxa pertaining to hip) is the term used to refer to deformity involving the hip as the shaft of the femur is bent outward. Genu valgum (from Latin genu pertaining to knee) is a deformity of the knee resulting in knock-kneed legs where the knees are abnormally close together.1
