One of the most common signs observed in children with Rothbarts Foot is Lateral Ankle Instability. They frequently twist their ankles inwardly.  (This lateral ankle instability is the direct result of the excessive foot twist observed in Rothbarts Foot.)

  • Foot twist biomechanically destabilizes the ankle joint, this can lead to frequent, inward twisting of the ankle joint.
  • Inward twisting of the ankle joint places the CalcaneoFibular Ligament (CFL) on a stretch.  
  • Repetitively stretching of the CFL further destabilizes the ankle joint.
  • The ankle joint becomes more and more prone to inversion type injuries.


Ankle Stress Test - heel bone is plantar flexed and inverted, AP Ankle Xray is taken


If the CFL is severely stretched (Grade II ankle sprain), Xrays will demonstrate an angulation between the talar dome and the tibial plafond (e.g., a talar tilt) (See Animation below)
