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.
Genu varum (also called bow-leggedness, bandiness, bandy-leg, and tibia vara) is a varus deformity marked by (outward) bowing at the knee, which means that the lower leg is angled inward in relation to the thigh's axis, giving the limb overall the appearance of an archer's bow.
Varus may refer to: Var River or Varus, a river in France; Stura di Lanzo or Varus, a river in Italy; Varus deformity, a medical term for the inward angulation of the distal segment of a bone or joint Coxa vara, affecting the hip; Genu varum, affecting the knee; Hallux varus, affecting the big toe; Cubitus varus, affecting the elbow
The terms "varus" and "valgus" always refer to the direction in which the distal segment of the joint points. The original Latin definitions for varus and valgus were the opposite of their current usage. [2] For a discussion of the etymology of these words, see the entry under varus. A mnemonic to remember the two deformities is that valgus ...
Hallux varus is a clinical condition characterized by medial deviation of the great toe at the metatarsophalangeal joint. [ 2 ] This condition, when acquired by adults, is usually caused by sports injury, surgical overcorrection of hallux valgus , or underlying causes such as arthritides .
Cubitus varus is a varus deformity in which the extended forearm is deviated towards midline of the body. Cubitus varus is often referred to as "Gunstock deformity", due to the crooked nature of the healing.
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%.
Pes cavus can occur from four primary causes: neurological conditions, trauma, undertreated clubfoot, or idiopathic with other underlining conditions. [9]Bilateral presentation (i.e., in both feet) often occurs due to a hereditary or congenital source, whereas a unilateral presentation (i.e., in one foot) is often the result of trauma.
