The anatomy of the foot and ankle is a complex set of bones, tendons, ligaments and muscles designed for both mobility and stability. The ankle is a hinge joint formed by the tibia and fibula (lower leg bones) and the talus (a bone in the foot). Together, they allow for up-and-down movement of the foot.
The foot itself is composed of 26 bones, organized into three main regions: the hindfoot, midfoot, and forefoot. The hindfoot includes the heel bone (calcaneus) and the talus, which connect to the ankle. The midfoot consists of a series of small bones called the tarsals, forming the arch of the foot.
The forefoot includes the metatarsals and phalanges (toe bones). Ligaments, tendons, and muscles support these bones, providing flexibility for walking, running, and balance, while absorbing impact. Key structures like the Achilles tendon and plantar fascia play critical roles in foot function and movement.
This post seeks to review some of that key anatomy. Compartments of the leg Anterior compartments of the leg Compartments of the Leg The anterior compartment of the leg is located at the front of the lower leg and is the primarily dorsiflexor.
It contains four muscles: the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and fibularis tertius. These muscles are innervated by the deep fibular nerve and supplied by the anterior tibial artery. The lateral compartment of the leg contains two muscles: the fibularis longus and fibularis brevis.
If you are experiencing symptoms that may be related to foot and ankle anatomy, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
