Bony Anatomy of the Foot: There’s More Than One Arch? 

The foot is a complex structure consisting of 26 bones.

 

Each has its own individual shape, joint surface and role in providing structure and function to not only your foot and lower limb, but the rest of our body.

 

Your feet when aligned in an optimal position provide a sure foundation for gait (locomotion).

 

Most people are familiar with simple surface anatomy of the foot however it is much more complex beneath the surface.

 

Below is a diagram demonstrating the bony anatomy of the foot.

 

 
Identifiable below is the Medial Longitudinal Arch (MLA) of the foot. This consists of the calcaneus, talus, navicular, medial/intermedial cuneiform and 1st metatarsal. This however, is not the only arch within the foot.

 

The Lateral Longitudinal Arch (LLA) and Transverse Arch (TA) are just as important. The LLA lies on the opposite side to the MLA. It consists of the calcaneus, cuboid and 5th metatarsal. The TA unlike the MLA and LLA, is less obvious to the eye and lies within the ball of the foot. This arch consists of the 1st through to 5th metatarsals.

 

All three arches of the foot play an integral role in adapting the foot to the ground and if compromised, can result in pain and injury.
