Genu varum may resolve spontaneously with modification of life style activities or after receiving medical treatment. Rickets usually causes bone deformities in all four extremities. Rickets may also have genetic causes, occasionally called resistant rickets. Insufficient dietary intake of calcium is another contributing factor. Nutritional rickets is due to unhealthy life style habits as insufficient exposure to sun light which is the main source of vitamin D. Nutritional rickets is an important cause of childhood genu varum or bow legs in some parts of the world. By the time a normal child begins to walk, the lower limbs are prepared, both by their general direction and by the rigidity of the bones which form them, to support the weight of the body. While these changes are occurring, the bones, which at first consist principally of cartilage, are gradually becoming ossified.

The knee-joints approach one another the femur slopes downward and inward towards the knee joints the tibia become straight, and the sole of the foot faces almost directly downwards. During the first year of life, a gradual change takes place. 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.

Childhood Ĭhildren until the age of 3 to 4 have a degree of genu varum. The remaining causes are occupational, especially among jockeys, and from physical trauma, the condition being very likely to supervene after accidents involving the condyles of the femur. Skeletal problems, infection, and tumors can also affect the growth of the leg, sometimes giving rise to a one-sided bow-leggedness. Thus the chief cause of this deformity is rickets. If a child is sickly, either with rickets or any other ailment that prevents ossification of the bones or is improperly fed, the bowed condition may persist.
