Metatarsal
Definition:

(3) Considerable spontaneous correction of deformity can be expected in the younger child (under age 10 years), but one should be aware that sagittal plane and rotational malalignment of the metatarsal heads may cause significant problems.
(4) Radiographic manifestations include endosteal sclerosis of the neurocranium with loss of the diploë, osteosclerosis and hyperostosis of the mandible with absence of the normal antegonial notches, endosteal sclerosis of the diaphyses of long bones (including metacarpals and metatarsals), and osteosclerosis of the pelvis.
(5) Therefore, the plantar forces acting under the metatarsal heads of the 1st, 2nd and 5th rays and under the pads of the 1st and 2nd toes were measured during walking, so that with the aid of anthropometric information pertaining to the forefoot, reaction forces in the flexor tendons and in the joints could be estimated.
