Compensatory Anteversion

  • Note the decrease in left foot pronation (dark shoes) as the child subconsciously rotates his left femur internally. 
  • Note the increase in left foot pronation (white shoes) when the child is instructed to consciously prevent his left femur from rotating externally.

These photos were taken on the same day (12 year old male patient).

​       Anteversion - Internal Femoral Rotation

A frequent subconscious compensation seen in children with Rothbarts Foot is to rotate their femurs internally (e.g., anterversion) in order to diminish or eliminate foot discomfort associated with abnormal pronation.

(3)  Metatarsus Adductus

A transverse plane structural deformity in which the metatarsals are medially deviated in relation to the longitudinal axis of the lesser tarsus, with the apex of the deformity at Lisfranc’s articulation (Yu and Wallace, 1987) - See Photos and Xray Below

Discussion

Frequently in Children with a Rothbarts Foot , the child subconsciously rotates his femurs internally to diminish the discomfort/aching in his feet that frequently occurs with abnormal pronation.
