Living with Congenital vertical talus

A rare birth difference of the foot (rocker-bottom foot) in which a foot bone sits in the wrong position.

Understanding Congenital vertical talus

Congenital vertical talus, sometimes called rocker-bottom foot, is a rare foot difference in which the talus bone forms in the wrong position.

Other foot bones shift on top of it. The front of the foot points up, and the bottom is stiff and flat with no arch, curving outward like the bottom of a rocker. One or both feet can be affected. It can occur on its own or with a genetic syndrome or a nerve and muscle condition.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Rocker-bottom foot
  • Flat feet
  • Stiff foot with no arch
  • Short Achilles tendon
  • Foot pain
  • Dislocated leg joints

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists and genetic specialists.

  3. Consider genetic testing

    Changes in HOXD10 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
