A varus deformity is an excessive inward angulation (medial angulation, that is, towards the body's midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points.
A chihuahua with a valgus deformity in the left forelimb. Valgus is a term for outward angulation of the distal segment of a bone or joint. The opposite condition is called varus, which is a medial deviation of the distal bone. The terms "varus" and "valgus" always refer to the direction in which the distal segment of the joint points.
Hip-knee-ankle angle. On projectional radiography, the degree of varus or valgus deformity can be quantified by the hip-knee-ankle angle, [7] which is an angle between the femoral mechanical axis and the center of the ankle joint. [8] It is normally between 1.0° and 1.5° of varus in adults. [9] Normal ranges are different in children. [10]
The valgus stress test or medial stress test is a test for damage to the medial collateral ligament of the knee. It involves placing the leg into extension, with one hand placed as a pivot on the knee. With the other hand placed upon the foot applying an abducting force, an attempt is then made to force the leg at the knee into valgus. If the ...

Varus stress test at 0° and 30° - Varus stress testing is accomplished while the patient is lying supine on an examination table. The physician supports the thigh against the side of the exam table and applies a varus force to the knee joint while holding the ankle or foot , first at 0°of flexion and then at 30°.
Most commonly, varus and valgus stress to the knee is added. These variations constitute different tests with different statistical performance and should not be confused with the original. According to some sources, the sensitivity of the McMurray test for medial meniscus tears is 53% and the specificity is 59%.
An angle of less than 84 degrees is regarded as talipes varus, and an angle of more than 94 degrees is regarded as talipes valgus. [ 25 ] For ligamentous injury, there are three main landmarks on X-rays: The first is the tibiofibular clear space , the horizontal distance from the lateral border of the posterior tibial malleolus to the medial ...
