Foot and Ankle

The foot and ankle in the human body work together to provide balance, stability, movement, and Propulsion.

This complex anatomy consists of:

  • 26 bones
  • 33 joints
  • Muscles
  • Tendons
  • Ligaments
  • Blood vessels, nerves, and soft tissue

Ankle Fractures

The ankle joint is composed of three bones: the tibia, fibula, and talus which are articulated together. The ends of the fibula and tibia (lower leg bones) form the inner and outer malleolus, which are the bony protrusions of the ankle joint that you can feel and see on either side of the ankle. The joint is protected by a fibrous membrane called a joint capsule, and filled with synovial fluid to enable smooth movement.

Foot Fracture

The hind foot is separated from the midfoot by the mediotarsal joint and the midfoot is separated from the forefoot by the Lisfranc joint. Muscles, tendons and ligaments support the bones and joints of the feet enabling them to withstand the entire body’s weight while walking, running and jumping. Despite this, trauma and stress can cause fractures in the foot. Extreme force is required to fracture the bones in the hind foot. The most common type of foot fracture is a stress fracture, which occurs when repeated activities produce small cracks in the bones.

Heel Fractures

The calcaneus or heel bone is a large bone found on the rear part of the foot. The calcaneus connects with the talus and cuboid bones to form the subtalar joint of the foot. A fracture is a break in a bone from trauma or various disease conditions. The types of fracture to the calcaneus depend on the severity and include stable fractures, displaced fractures, open fractures, closed fractures and comminuted fractures.

Lisfranc (Midfoot) Fracture

Tarsometatarsal joint refers to the region found in the middle of the foot. It is also called as Lisfranc joints. It is a junction between the tarsal bones (group of seven articulating bones in the foot) and metatarsal bones (a group of five long bones in the foot). A deformity in the tarsometatarsal region can be due to arthritis and traumatic motor accidents.

Stress Fractures of the Foot and Ankle

A stress fracture is described as a small crack in the bone which occurs from an overuse injury of a bone. It commonly develops in the weight bearing bones of the lower leg and foot. When the muscles of the foot are overworked or stressed, they are unable to absorb the stress and when this happens the muscles transfer the stress to the bone which results in stress fracture.

Talus Fractures

The talus is a small bone at the ankle joint that connects the heel bone and the two bones of the lower leg, enabling the up and down movement of the foot. Fractures in the talus bone may occur due to a fall from great heights, motor vehicle accidents or twisting of the ankle. The symptoms include severe ankle pain, inability to walk, swelling and tenderness.

Toe and Forefoot Fractures

The forefoot is the front of the foot that includes the toes. Fractures occurring in this part of the foot are painful but very often not disabling. There are 2 types of fractures namely, traumatic fracture and stress fracture. Traumatic fractures occur when there is a direct impact of your foot on a hard surface.
