Walking (Gait) Abnormalities | Symptoms & Causes
What causes pediatric gait abnormalities?
Tibial torsion
Tibial torsion is the turning of a child’s lower leg (tibia) either inward (internal tibial torsion) or outward (external tibial torsion). The condition often improves without treatment, usually before a child turns 4.
Some children with tibial torsion wear a night brace between 18 to 30 months old, but this is not common. Doctors only consider surgery for tibial torsion if a child still has the condition when they are 8 to 10 years old and having significant walking problems.
Femoral version
Femoral version describes a child’s upper leg bone (femur) that twists inward or outward. Inward twisting of the femur (femoral anteversion) causes the feet to point inward. Signs of femoral anteversion usually first become noticeable when a child is between 2 to 4 years old, a time when inward rotation from the hip tends to increase. The condition usually gets better without treatment.
Outward twisting of the femur is called femoral retroversion and causes the feet to point outward. It is less common than femoral anteversion. In some cases, femoral retroversion may delay a child’s walking, however, the condition often gets better without medical intervention.
Doctors consider surgery for femoral anteversion or femoral retroversion only if a child is older than 9 and has a very severe condition that causes a lot of tripping and an unsightly gait.
Bowlegs and knock knees
Bowlegs is an outward curve of the legs at the knees. Knock knees is an inward curve of the legs at the knees. Both bowlegs and knock knees are common stages of development and usually self-correct as a child grows.
Flatfeet
Flatfeet are normal in infants and young children. Children have flat feet when the arches in their feet have not yet developed and their entire feet press against the floor. The arches develop throughout childhood until about age 10.
Metatarsus adductus
Metatarsus adductus is a common positional deformity that causes a child's feet to bend inward from the middle of the foot to the toes. In severe cases, it may resemble clubfoot. The condition improves on its own most of the time.
Babies with severe metatarsus adductus may need treatment, which usually involves special exercises, casts, or special corrective shoes. These treatments have a high rate of success in babies from 6 to 9 months old.
Limping
Sudden limping is most likely due to pain caused by a minor, easily treated injury. Splinters, blisters, or tired muscles are common culprits. Less often, limping can involve a more serious problem such as a sprain, fracture, dislocation, joint infection, or autoimmune arthritis. In rare cases, a limp may be the first sign of a tumor.
Non-painful chronic limping may be sign of developmental problem, such as a leg length discrepancy or hip dysplasia or a neuromuscular problem, such as cerebral palsy.
Toe walking
Toe walking is a common gait abnormality, particularly in young children who are just starting to walk. In most cases, this will resolve on its own over time without intervention. However, children who walk normally for a period and then later begin to walk on their toes, or children with tightness of their Achilles tendons, should be evaluated by a physician.
Many cases of persistent toe-walking run in families or are caused by tight muscles. Treatment may involve observation, physical therapy, bracing, casting, or surgery. In some cases, toe-walking may indicate a neuromuscular disorder such as cerebral palsy or it could be a sign of developmental dysplasia of the hip or leg length discrepancy.
Walking (Gait) Abnormalities | Diagnosis & Treatments
How are gait abnormalities diagnosed?
Your child’s doctor will perform a physical exam and watch your child as they walk or run. They may look to see whether your child’s legs are shaped the same or differently. They may also ask if your child shows any signs of being in pain when they walk and whether any members of your close family have had long-term walking problems.
Other diagnostic procedures may include:
- X-ray: A diagnostic test that produces images of internal tissues, bones, and organs that can be used to look at bone structure and alignment.
- Magnetic resonance imaging (MRI): A diagnostic procedure that produces detailed images of soft tissues and structures within the body. This test is sometimes used to rule out any associated abnormalities of the spinal cord and nerves.
- Computerized tomography scan (also called a CT or CAT scan): A diagnostic imaging procedure that shows detailed images of the bones and joints.
How are pediatric gait abnormalities treated?
In most cases, a child with an abnormal gait is observed over the course of several years. The doctor will monitor your child’s walking patterns to ensure their legs continue to develop and their walking patterns become more typical over time. Fortunately, most causes of gait abnormalities will resolve without any intervention as a child grows.
If a gait abnormality is caused by an injury or developmental condition, your child’s doctor will treat that condition. Treatment for gait abnormalities that do not resolve may include surgery and is something to discuss with your doctor.
