Everyone is different. This couldn’t be more accurate in the case of a tarsal coalition.

When the bones of the foot fuse together, this is known as tarsal coalition. The tarsal bones are the seven larger bones that make up the back of the foot; behind the toes and the attached metatarsal bones.  Bone coalitions are not too common. Tarsal coalition is genetically inherited and can occur in both feet.  Commonly diagnosed during childhood, A tarsal coalition may present as a flat, rigid foot.  This condition restricts the natural movement of the bones in the foot, which is the main cause of pain. Pain is typically felt around the ankle joint, and is normally felt ‘deep’ within the foot.

The calcaneonavicular and talocalcaneal joints are the most common tarsal joins found. A tarsal joining is detected with specific x-ray views and CT scans that are more accurate in identifying the specific area of the joining.  There are a number treatments for this condition.

Sometimes a cortisone injection may be enough to settle a painful joint. Podiatrists routinely use orthotics and appropriate footwear which is designed to minimise unnatural movement of the joint, which will in turn minimise discomfort.  Some coalitions may still remain painful. Surgical intervention is often an option, and will either include a resection (separation) of the bones, or an arthrodesis (fusion) of the surrounding bones to limit painful movement.
