10. Convex Forefoot with Insufficiency of the First Ray
Abstract
There is a group of forefoot syndromes characterised by convexity of the plantar weight-bearing surface associated with insufficiency of action of the first ray. They may be subdivided as follows:
1.
Short first metatarsal
a)
Relative: due to congenital overlengthening of the second metatarsal in a planovalgus foot (Duddley Morton 1924a)
b)
Absolute: congenital shortening of first metatarsal
c)
Acquired: iatrogenic
2.
Short great toe: acquired, usually iatrogenic
3.
Hypermobility of first metatarsal, described by Courriades (1971)
