We talked about forefoot varus, forefoot supinatus and subsequent biomechanics in a recent onlinece.com course. Here is a great commentary on a review article we discussed as well as a great explanation about thew tru differences between at forefoot varus (rare) and the more common forefoot supinatus.
Take home message? FROM THE ARTICLE:
" In summary: both look the same, but they are totally different beasts:
a forefoot varus is bony and a forefoot supinatus is soft tissue
a forefoot varus is a cause of ‘overpronation’ and a forefoot supinatus is the result of ‘overpronation’
a forefoot varus is rare and a forefoot supintus is common
a forefoot varus cannot be corrected and a forefoot supinatus can be corrected"
