Definition of Cubitus valgus

Cubitus valgus: A deformity of the elbow resulting in an increased carrying angle (so that, with the arm extended at the side and the palm facing forward, the forearm and hand are held at greater than 15 degrees). Cubitus valgus can be due to a congenital malformation, as in Turner syndrome and Noonan syndrome, or be due to a fracture. Cubitus is the Latin word for elbow and valgus means angled outward.
