Children until the age of 3 to 4 have a degree of genu varum. The child sits with the soles of the feet facing one another; the tibia and femur are curved outwards; and, if the limbs are extended, although the ankles are in contact, there is a distinct space between the knee-joints. During the first year of life, a gradual change takes place.
Rickets, scientific nomenclature: rachitis (from Greek ῥαχίτης rhakhítēs, [6] meaning 'in or of the spine'), is a condition that results in weak or soft bones in children and may have either dietary deficiency or genetic causes. [2]
Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees. This results in the leg being shortened and the development of a limp.
Surgery may be necessary to treat misalignment of the hip (osteotomy of the pelvis or the collum femoris) and, in some cases, malformation (e.g., genu varum or genu valgum). [19] In some cases, total hip replacement may be necessary. However, surgery is not always necessary or appropriate. [20]
Knee: genu varum (from Latin genu = knee) — the tibia is turned inward in relation to the femur, resulting in a bowlegged deformity. Ankle: talipes varus (from Latin talus = ankle and pes = foot). A notable subtype is clubfoot or talipes equinovarus, which is where one or both feet are rotated inwards and downwards. [6] [7]
In some cases, children with type A deformities will also have an externally rotated femur, which could lead to bowing of the legs (genu varum). Type B — The femur bone is shorter on the proximal end (near the hip) and the defect affects both the femoral head (the ball) and the femoral shaft (the long part of the bone).
Divergence from the normal femorotibial angle is called genu varum if the center of the knee joint is lateral to the mechanical axis (intermalleolar distance exceeds 3 cm), and genu valgum if it is medial to the mechanical axis (intercondylar distance exceeds 5 cm). These conditions impose unbalanced loads on the joints and stretching of either ...
Mild genu valgum is diagnosed when a person standing upright with the feet touching also shows the knees touching. It can be seen in children from ages 2 to 5, and is often corrected naturally as children grow. The condition may continue or worsen with age, particularly when it is the result of a disease, such as rickets. [2]
