Congenital Metatarsus (Primus) Varus: Causes, Symptoms, and Treatment

If you have noticed that your baby's foot appears to be turned inward, they may have a condition called congenital metatarsus (primus) varus. This condition, also known as "pigeon toes," is a relatively common foot deformity that affects infants and young children.

Causes:

Congenital metatarsus (primus) varus is caused by abnormal positioning of the bones in the foot during fetal development. While the exact cause is unknown, it is believed to be related to genetics or intrauterine positioning. In some cases, the condition may also be associated with other developmental disorders.

Symptoms:

The primary symptom of congenital metatarsus (primus) varus is the inward turning of the foot. This may be noticeable at birth or become more apparent as the child begins to stand and walk. Other symptoms may include difficulty walking or running, pain or discomfort, and an uneven gait.

Treatment:

The treatment for congenital metatarsus (primus) varus depends on the severity of the condition. In mild cases, the condition may resolve on its own as the child grows and begins to walk. However, more severe cases may require treatment to correct the position of the foot. This may include the use of braces, special shoes, or casting to gradually realign the bones in the foot. In some cases, surgery may be necessary to correct the deformity.

If you suspect that your child may have congenital metatarsus (primus) varus, it is important to consult with a healthcare professional. Early diagnosis and treatment can help to prevent complications and improve your child's quality of life.
