What are Bowlegs?
Bowleg (also known as genu varum or “bow legs”) is a condition that causes both legs to curve outward. It typically can be seen when a child stands with the feet together and a space appears between the lower legs and knees.
Many children are born with bowleg, but bowing of legs usually goes away by the time a child is 2 and has been walking for a while.
What Causes Bowlegs?
Bowleg occurs most frequently in females and in African-American children. Children who are obese, or short, or who began walking early, are also at an increased risk for bowleg.
Bowlegs can be caused by:
- Blount’s disease, a growth disorder of the shin bone (also known as the tibia) possibly caused by effects of weight on the growth plate.
- Abnormal development or malformation of the bones.
- Bone fractures that do not heal properly.
- Lead or fluoride poisoning.
- Rickets, caused by a vitamin D deficiency.
Bowlegs Symptoms and Effects
Depending on the cause of bowleg, symptoms can differ from person to person. The most common signs and symptoms are:
- Knees that don’t touch when the feet are together and ankles are touching.
- Bowlegs that are present well after your child begins walking.
- Problems with the knee joints, when caused by Blount’s disease.
- Bowing that increases with time, when caused by Blount’s disease.
If the bowing is excessive, or if the condition persists into adolescence or adulthood, pain and problems with knee joint function are common long-term effects.
Bowlegs Diagnosis and Treatment
Bowleg can typically be diagnosed during a physical examination by measuring the distance between the knees.
