Valgus
Pronunciation: VAL-gus
A positional term describing an outward (lateral) deviation of a distal body segment relative to the proximal segment, frequently encountered in orthotic documentation of the knee, ankle, and foot.
Full Definition
Valgus describes an angulation in which the distal part of a limb or joint is deviated away from the midline of the body. In orthotic services, it is most commonly applied to the knee (genu valgum, or 'knock-knee'), ankle, and subtalar joint (hindfoot valgus). It is the functional opposite of varus. Editors must ensure that valgus and varus are used consistently and anatomically correctly within a document, as misuse can significantly alter clinical meaning. The terms are Latin in origin and are not typically italicised in modern clinical English.
Usage
Usage note: Do not italicise. Valgus and varus are among the most commonly transposed clinical terms; editors should flag any usage that appears anatomically inconsistent with the surrounding text.
