Tarsal (Bone) coalition is a rare but often misdiagnosed cause of flat and painful feet in children and some adults. The main cause of pain is due to the bones of the foot not separating resulting in stiffness and abnormal alignment of the foot. This problem may cause arthritis of the foot and ankle in the future.
Conservative therapy is the initial treatment. Conservative therapy includes: custom orthotics, special brace, physical therapy and stretching. If conservative care fails, surgical correction may be necessary.
Surgery of a tarsal coalition is based on removal of the coalition region. This is usually a very successful surgery in children. Surgery for adults may require fusion if the patient has severe arthritis.
