Clubfoot Outcome & Biomechanics

The JVL Researchers, in close collaboration with OIC orthopaedic surgeons, have published many studies on the treatment, outcome, and biomechanics of idiopathic clubfoot. An IRB approved database of more than 300 infants treated at OIC has been established to study all aspects of clubfoot treatment. Some of thequestions recently addressed:

  • How early should an infant with clubfoot begin treatment?
  • How important is it to apply the brace as recommended?
  • At what age should an infant with clubfoot be expected to walk?
  • Is there a correlation between severity of clubfoot and gender?

Current Research

Working with orthopaedic surgeons, JVL researchers designed a study to compare the corrective potential of among three surgical procedures commonly conducted in clubfoot patients who experience a relapse after 2 ½ years of age. Optical motion tracking was used to measure forefoot and hindfoot motions as a function of tension applied via the anterior tibialis.
