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.
If the calcaneal axis between these two bones is turned medially the foot is in an everted position (pes valgus), and if it is turned laterally the foot is in an inverted position (pes varus). [5] Calcaneal fracture, also known as lover's fracture and Don Juan fracture
Pes cavus commonly features a varus (inverted) hindfoot, a plantarflexed position of the first metatarsal, an adducted forefoot, and dorsal contracture of the toes. Despite numerous anecdotal reports and hypothetical descriptions, very little rigorous scientific data exist on the assessment or treatment of pes cavus.
Weight-bearing lateral X-ray showing the measurement of calcaneal pitch, which is an angle of the calcaneus and the inferior aspect of the foot, with different sources giving different reference points. [13] A calcaneal pitch of less than 17° or 18° indicates flat feet. [11]
Surgical correction may be used to treat significant angular limb deformity, usually carpal valgus, that is causing discomfort and impaired limb use. [6] For younger patients with significant growth potential to the affected area remaining, a surgery involving cutting the ulna to release its hold on the radius is possible; this allows the ...
The degree of varus or valgus deformity can be quantified by the hip-knee-ankle angle, [36] which is an angle between the femoral mechanical axis and the center of the ankle joint. [37] It is normally between 1.0° and 1.5° of varus in adults. [38] Normal ranges are different in children. [39]
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]
