Valgus deformity

As valgus (from Latin valgus - wrong ) is referred to in connection with a limb deformity in which the body part has more distant beyond the industry standard of the midline, while the varus means a deviation inside. This causes the affected joint (or bone ) is bent inwards and inside often above.

At the knee joint, this is a deviation of the lower leg to the outside, which corresponds to an X- leg when the normal X -position (physiological valgus ) is exceeded by 7 degrees; thus the inner parts of the joint are often prominent. The technical term is the Genu valgum.

In principle, a valgus possible at all joints and bones of the extremities and can cause a unilateral biomechanical overload to premature osteoarthritis of the affected joint or nearest.

In a knock-knee ( genu valgum ) this can lead by an increased load on the outer joint space to an externally stressed valgus gonarthrosis.

Other examples of a valgus are:

  • Coxa valga ( Hüftfehlstellung ): The femoral neck is too steep relative to the femoral shaft, the real CCD angle (the angle between the femoral head, femoral neck and femoral shaft ) is above 130 degrees, normally between 120-130 °. The print collection zone of the femoral head is smaller, the joint is then also arthrosis at risk, the stronger, the higher the CCD angle. The coxa valga is therefore considered Präarthrose and is next to the Pfannendysplasie a component of hip dysplasia. In the valgus position, the distal portion of the midline at the standard position, the proximal portion. So far is not the Schenkalhals " steeper " is based on the shaft, but the shaft has, in relation to the neck of the body center path.
  • Hallux valgus: the big toe points outward and often beset the smaller neighboring toes to give the big toe joint emerging as bales on Fußinnenrand. The cause is usually but an opposite varus orientation of the first metatarsal ( metatarsus primus varus ).
  • Pes valgus or valgus calcaneus called the ( especially in children often observed ) Foldable base, is in the heel bone ( calcaneus ) tilted outward.
  • Cubitus valgus is often a plant-specific deformity of the elbow, in which the inner elbow condyles ( medial epicondyle of the humerus ) and the forearm protrudes prominently facing away from the fuselage.
  • Carpus valgus as a result of an Early Ulnafugenschlusses
