Bow legs

Bow legs is a condition characterized by an outward curvature of the lower leg in relation to the thigh, giving the appearance of an archer's bow. The medical term for bow legs is genu varum.

Causes

Bow legs can occur as a result of various medical conditions or diseases. Some of the common causes include:

• Rickets: A disease caused by vitamin D deficiency, which affects the development and hardening of the bones.
• Blount's disease: A growth disorder that affects the shin bone, causing the lower leg to turn inward and resemble a bow.
• Paget's disease: A chronic disorder that can result in enlarged and misshapen bones.
• Dwarfism: Certain types of dwarfism can cause bow legs.

Symptoms

The primary symptom of bow legs is a noticeable gap between the feet and ankles when the knees are touching. Other symptoms can include:

• Knee pain
• Difficulty walking
• Reduced range of motion in the legs

Treatment

Treatment for bow legs depends on the underlying cause. In children, bow legs often correct themselves over time. However, in some cases, treatment may be necessary and can include:

• Vitamin D supplements: If rickets is the cause, vitamin D supplements can help.
• Braces or splints: These can help to correct the shape of the leg in children.
• Surgery: In severe cases, surgery may be necessary to correct the shape of the leg.
