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
- Blood vessels, nerves, and soft tissue
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 (medial) and outer (lateral) malleolus,
The foot has 26 bones, and can be divided into 3 parts:
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.
Lisfranc (Midfoot) Fracture and Midfoot Arthritis
The tarsometatarsal joint (Lis Franc Joint) is the region found in the middle of the foot. is a junction between the tarsal bones (group of seven “Hind Foot” articulating bones in the foot underneath the ankle) and the metatarsal bones (a group of five long bones in the “fore foot”).
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.
The talus is the small bone in the ankle joint that connects the heel bone and the bones of the lower leg. The shape of the talus enables the up and down movements of the foot.
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.
