The opposite of varus is called valgus. EX: Varus deformity results in a decreased Q angle of the knee joint. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For example, in a valgus deformity of the knee, the distal part of the leg below the knee is deviated outward, in relation to the femur, resulting in a knock-kneed appearance. Conversely, a varus deformity at the knee results in a bowlegged appearance, with the distal part of the leg deviated inward, in relation to the femur. However, in relation to the mid-line of the body, the knee joint is deviated towards the mid-line. EX: Valgus deformity results in an increased Q angle of the knee joint. TerminologyThe terminology is made confusing by the etymology of these words.
When the terminology refers to a bone rather than a joint, the distal segment of the bone is being described. Thus, a varus deformity of the tibia (i.e. a mid-shaft tibial fracture with varus deformity) refers to the distal segment in a varus alignment compared to the proximal segment. Examples
