Definition of bow legs

The term "bow legs" is used to describe a condition in which the legs appear to bend outwards at the knees when standing with the feet together. This temporary outward bowing of the legs in a newborn infant is a natural and normal posture called Genu Varum, as the bones in the thighs and knees are still soft and pliable. As the child grows and begins to walk, the bones harden and straighten naturally, causing the legs to become more vertical. The medical term for bow legs is Genu Varum, and it can be caused by a variety of factors. One common cause is vitamin D deficiency, which can lead to Rickets, a bone disease that results in weak and misshapen bones. Genetic factors can also contribute to the condition, as some individuals may be born with bowed legs due to abnormalities in bone development. More rarely, bow legs can be indicative of underlying diseases such as Cower's syndrome, which affects the growth of bones, or Blount's disease, which is caused by excess weight bearing on the inner knees at an early age. While most cases of bow legs resolve on their own with time and proper nutrition, severe or persistent cases may require medical intervention such as bracing, orthopedic surgery, or physical therapy to correct the alignment of the legs. However, in the majority of cases, the temporary outward bowing of newborn legs will straighten as the child grows and develops. Therefore, it is essential to differentiate between the normal bowing of newborn legs and true cases of Genu Varum, as the course of treatment may differ based on the underlying cause.
