Tarsal Coalition Symptoms and Diagnosis

Symptoms of Tarsal Coalition

Children with tarsal coalition may have foot pain. Usually, you cannot see an arch in their foot or feet when they stand up.

Tarsal Coalition Diagnosis

First, the doctor examines your child's foot. The doctor will look at their feet as they stand up. We may ask your child to stand on tiptoe or dangle their foot in the air as they sit on an exam table.

When children have a form of rigid flatfoot, such as a tarsal coalition, we usually cannot see an arch in the foot when they stand on tiptoe or let their foot hang down. In other types of flatfoot, the arch appears when children stand on tiptoe or let their feet dangle.

We also check the joints in your child's feet and ankles. If your child's ankle does not move much, it could mean that the Achilles tendon is shortened or tight. That may make it more likely they will have pain and disability.

We may take X-rays to see if your child's calcaneus and navicular bones are joined together. To check the talus and calcaneus bones, we use a CT (computed tomography) scan.
