Tarsal Coalition - Carrollton, TX
Dr. Heier is a Carrollton, TX based board certified foot surgeon providing effective treatment for an array of orthopedic conditions. He specializes in using advanced non-surgical and surgical techniques to treat Tarsal Coalition.

Tarsal Coalition

Tarsal Coalition refers to a condition characterized by an unusual growth of cartilage or fibrous tissue around tarsal bones, causing them to form an unusual connection. The tarsal bones, including the calcaneus, talus, navicular, cuboid and cuneiform, are located in the located in the middle as well as back of the foot. These bones play an important role in the normal functioning of the foot.

Types Of Tarsal Coalition:

  • Calcaneonavicular Coalition: In this condition, calcaneus (largest foot bone) is not separated from the navicular bone (present at the top of midfoot). The tissue that connects the two bones looks like a bar and is composed of cartilages or fibrous tissues.
  • Talocalcaneal Coalition: This defect refers to incomplete differentiation of calcaneus and talus bone (present in the ankle).
  • Calcaneocuboid Coalition: The condition involves partial separation of calcaneus and the cuboid bone (located at the bottom of the foot).
  • Talonavicular Coalition: The deformity occurs when talus and the navicular bones are not distinct.
  • Cubonavicular Coalition: This condition refers to attachment of cuboid and navicular bones.

Causes Of Tarsal Coalition

  • Improper formation of foot bones during fetal development
  • Arthritis
  • Prior injury to the feet
  • Infection

Symptoms Of Tarsal Coalition

  • Fallen arches
  • Pain on the top and outer portion of the foot
  • Stiffness
  • Fatigued or tired legs
  • Muscle spasms in leg that causes changes in gait
  • Limping
  • Reduced range of motion of foot
  • Excessive inward rolling of the ankle

Diagnosis Of Tarsal Coalition

The doctor may conduct a physical test to locate the site of pain. He may inquire about previous injuries, recent involvement in an athletic activity or weight gain.

Imaging tests:

  • X-Ray Test – X-Ray test may be done to visualize the anteroposterior (top), internal (angled side) and lateral (straight side) of the foot.
  • Computed Tomography (CT) Scan – A CT scan may be recommend by the doctor to evaluate the severity of the condition.  
  • Magnetic Resonance Imaging (MRI) - It may reveal any abnormal cartilage or tissue growths in the foot.

Treatment For Tarsal Coalition

Non-Surgical Treatment

  • Medications: Anti-inflammatory drugs may be prescribed to provide relief from pain
  • Orthotics:  Using orthotics like insoles and braces may help to relieve the pressure off the foot while walking. This may further decrease inflammation caused by the condition.
  • Physical Therapy:  Exercises that improve foot’s range of motion may be suggested.

Surgical Treatment

  • Excision surgery: In case of Calcaneonavicular Coalition, the connecting tissue between the bones is replaced with muscles or fat tissue. This forms a physical barrier which prevents the bones from reconnecting.
  • Fusion surgery: When the Tarsal Coalition is severe, surgery may be required to fuse the bones together. In this, the cartilage that covers the joints is removed which allows the bones to grow together. Screws and pins may be used to keep the bones in place.
