Humans usually have five toes on each foot. When more than five toes are present, this is known as polydactyly. Other variants may include syndactyly or arachnodactyly. Forefoot shape, including toe shape, exhibits significant variation among people; these differences can be measured and have been statistically correlated with ethnicity. [3]
Morton's toe is the condition of having a first metatarsal bone that is shorter than the second metatarsal (see diagram). It is a type of brachymetatarsia. [1] This condition is the result of a premature closing of the first metatarsal's growth plate, resulting in a short big toe, giving the second toe the appearance of being long compared to the first toe.
This is the rarest form of brachydactyly. It is most often part of another condition that someone is born with. Type E shortens the bones in the hands and feet along with the bottom bone in the fingers. Instead of making the fingers and toes look shorter, it makes the hands and feet look smaller.

A long bone is one that is cylindrical in shape, being longer than it is wide. However, the term describes the shape of a bone, not its size, which is relative. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges).
In 2010 some football players began testing a new sock that incorporated a rubber silicone pad over the foot to provide protection to the top of the foot. [8] Stress fractures are thought to account for 16% of injuries related to sports participation, and the metatarsals are the bones most often involved.
Ectrodactyly, also known as split-hand malformation, is the congenital absence of one or more central digits of the hands and feet. Consequently, it is a form of oligodactyly. News anchor Bree Walker is probably the best-known person with this condition, which affects about one in 91,000 people.
In the foot—the first metatarsal bone usually has two sesamoid bones at its connection to the big toe (both within the tendon of flexor hallucis brevis). [10] One is found on the lateral side of the first metatarsal while the other is found on the medial side. In some people, only a single sesamoid is found on the first metatarsal bone.
The digit, also known as digitus or digitus transversus (Latin), dactyl (Greek) or dactylus, or finger's breadth – 3 ⁄ 4 of an inch or 1 ⁄ 16 of a foot. [1] [2] (about 2 cm) In medicine and related disciplines (anatomy, radiology, etc.) the fingerbreadth (literally the width of a finger) is an informal but widely used unit of measure. [3] [4]
