Bowed Legs in Babies & Toddlers

When babies stand up and walk, it’s a milestone for their parents. However, sometimes, children have bowed legs or knocked knees (the reverse of bowed legs). If your child displays this health condition, here’s everything you need to know about bow-leggedness in babies.

What Does Bowed Legs Mean?

Bowed legs in infants is a situation wherein a child’s feet and ankles touch, but not his knees. It starts becoming noticeable as the child tries to stand.

Are Bowlegs Normal In Babies?

Bowed legs are perfectly normal in children, especially when they’re just learning to walk. But they can become a concern over time. Most children have bowed legs because of the foetal position, but it normally corrects itself over time. As children develop better muscles in their legs and learn how to stand and walk, their legs straighten out.

Symptoms of Bow-Leggedness in Babies

Bowed legs are easily noticeable in children. When your child’s legs don’t straighten out even after toddlerhood, it’s a cause for concern.

The symptoms of bow-leggedness in babies include:

• Awkward walking pattern (i.e. not direct or forward).There may either be either in-toeing or out-toeing. The feet may point inward instead of pointing straight while walking or running or the feet may curve outward instead of pointing straight.
• Lack of coordination in movement
• Moderate pain or discomfort

Causes

As mentioned above, bowed legs are quite normal in children because of the position they’ve been in, in the womb. Their legs haven’t had time to straighten out. Other causes of bowed legs include:

1. Physiological Genu Varum

A variation in normal appearance across children that results in some toddlers appearing more bow-legged than others. There is symmetrical and painless bowing and this problem will resolve spontaneously without treatment, as a result of normal growth.

2. Blount’s Disease

A disease resulting in the abnormal growth of the tibia (shinbone).

3. Rickets

A metabolic disorder that affects growth in children.

4. Bone Dysplasia

An uncommon hereditary condition wherein the growth of joints and bones is abnormal.

5. Deficiency of Vitamin D

A lack of vitamin D can weaken a child’s legs, causing them to become bowed.

6. Bowing Fractures

A result of injury, this happens when the bone bends but doesn’t break and results in swelling or pain.

7. Lead or Fluoride Poisoning

A very rare process where lead or fluoride in the body poisons the tissue of the bone, creating more un-mineralized material in the bone and allowing them to weaken over time, potentially leading to bowing.

What Makes Babies Prone to Developing Bowed Legs?

Bowlegs in toddlers and older children is often due to Blount disease. Blount disease is common in kids who:

• Are overweight
• Have started walking at an early age
• Have a family history of bowed legs

How Long Does This Condition Last?

Bowed legs normally last until 24 months after the baby begins to walk, usually disappearing by 3 years of age. If, however, the curve of your child’s legs appears to be extreme, mention it to your paediatrician at your next appointment.

Diagnosis of Bowed Legs in Infants

Your doctor will conduct a brief examination to see how severe the curve in the legs is. Then, he/she will look at your child’s medical history and conduct tests to determine what the issue may be.

In most of the cases, the diagnosis is as follows:

1. Physical Examination

The doctor will physically examine your child to observe the curve of the bow and determine the severity of the case.

2. Blood Test

Blood tests will be performed to determine if there’s a deficiency of vitamin D.

3. X-Ray

An X-ray may be conducted to rule out Blount’s disease.

4. Other Tests

The doctor may also try to rule out other diseases affecting the legs, such as rickets.

Treatment for Bowed Legs

Bowed legs are rarely treated, especially in children. Severely curved legs may require surgery, but this may only be done when the child is older. While braces and other corrective shoes have been used in the past, they are not recommended.

Non-Surgical Treatment Options

• For most children with bowed legs, they will be seen every six months by the doctor until the problem resolves itself.
• Consult a specialist for regular follow-ups and limit complications that include gait abnormalities, knee joint instability, meniscal tears and degenerative joint disease.

2. Surgical Treatment Options

• Guided Growth Surgery

A unique figure-eight shaped device allows gradual correction of the deformity. There are screws attached to the plate and the bone that help in decreasing the compression on the growth plate and allowing for increased flexibility. The growth plate restricts the bone growth to one side of the deformity. allowing the bone to gradually realign.

• Tibial Osteotomy

In this case, surgery is done on the shinbone via a cut just below the knee, and the shinbone is then reshaped to help correct its alignment. The bone is normally held in place by screws or some sort of plate during the recovery process.

What If the Bowed Legs Are Left Untreated?

Having bowed legs can cause complications later in life. These include:

• Arthritis
• Stress on the knees and hips
• Bone and joint problems
• Difficulty walking

When Should You Worry?

If your child’s legs remain bowed beyond three years of age, you may need to consult a specialist. Also, look for the following symptoms:

• Difficulty walking
• Problems with advanced forms of movement, like running
• Inability to stand upright
• Muscle and bone-related problems
