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.
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]
Varus: the heel is inverted, or turned in, forcing one to walk on the outside of the foot. This is a natural motion but in clubfoot the foot is fixed in this position. 4 Equinus: the foot is pointed downward, forcing one to walk on tiptoe. This motion occurs naturally, but in clubfoot the foot is fixed in this position.
Valgus stress at 0° and 20°- This test puts direct stress on the medial knee structures, reproducing the mechanism of injury. Valgus stress testing is done with the patient supine on the exam table. The lower extremity, supported by the examiner, is abducted. The examiner's fingers monitor the medial joint space for gapping while placing the ...
For example, a stroke can result in unilateral weakness, meaning weakness on one side of the body. Varus (from Latin 'bow-legged') and valgus (from Latin 'knock-kneed' ) are terms used to describe a state in which a part further away is abnormally placed towards (varus) or away from (valgus) the midline.

X-ray showing measurements of HV and IM angles of hallux valgus. Bunions can be diagnosed and analyzed with a simple x-ray , which should be taken with the weight on the foot. [ 10 ] The hallux valgus angle (HVA) is the angle between the long axes of the proximal phalanx and the first metatarsal bone of the big toe.
Bunion (hallux valgus) deformity is actually part of a complex of anatomical derangements of protruding mass (bunion), buckling of big toe (hallux valgus) and the bone behind it (metatarsus primus varus), displaced sesamoid bones (detrimental to the important walking function of big toe), collapsed metatarsal arch and several other secondary changes that are the domino effects of metatarsal ...
