Short first metatarsals create an imbalanced metatarsal parabola. This in turn leads to biomchanical imabalnce and altered gait leading to either disorders of over-pronation such as hallux valgus, hallux rigidus. Compensations for inability to flex the 1st MTPJ on weightbearing include abduction of the foot which can lead to hyperkeratosis overlying the lesser mets.
Could this be more prevalent in indian heritage patients?

Dear Annette Thompson, Thanks for your interest in my research.
I have not traced the metatarsal parabola in my subjects. Will have to try do it. Did you refer to my publication when mentioning the short first metatarsals? I ask this because, none of my subjects had reported any problems with their feet.
Most of my subjects were from a particular state in India, hence it may not be appropriate to project the values to whole of India (which is a very large geographical area with a multitude of races).

Hope this satisfies your queries. Thanks for you correspondence.

Sure none of your subject reported problems with their feet as you excluded those with foot pain. You have a wonderful source of metatarsal parabola data if you could insert the parabola on your images. Your figure 1 for example has a perfect parabola. What is needed is another group of only metatarsal foot pain/plantar metatarsal callused subjects to compare their parabolae of the non symptomatic group - results would be most interesting. See my article in Foot & Ankle Surgery on metatarsal lengths as this raises questions on impact of mismatched post surgical footwear.
Best regards, Anette
Very interesting matter of your discussion - specific of foot forms in different nations depends on anthropology and lifestyle! . For example there are a lot of hypermobile 1st metatarsal in Russia, a lot of pttd in Africa I noted.
