Functional versus Osseous Forefoot Varus


Do X-rays show osseous forefoot varus?
Is this how one distinguishes between osseous and functional forefoot varus (also referred to as forefoot supinatus deformity)? I went to a podiatrist who said I had forefoot varus. I went to an orthopedic surgeon who said that he saw no evidence of forefoot varus in the X-Rays.
I see on the web that if you are given orthotics for osseous forefoot varus, which I was, but have functional forefoot varus, damage is done to the first metatarsophalangeal joint.


  1. i have a question.what is a “normal” range of forefoot varus in regard to aligning the leg, foot and pedal stroke on a bicycle. is there an average amount of forefoot varus that has been determined for the average american adult male and adult female?thanks,mk

  2. Generally x-rays do not show this. The reason is an x-ray is a 2 dimensional representation of a 3 dimensional object. Forefoot varus by definition is a relative inversion of the forefoot on the rearfoot.As far as the question of the orthotics goes, I might disagree with your statement since there are many types of orthotics and variations.
