Using medical images (X-rays, ultrasound, etc.) to view the foot and ankle.

Lateral movement of the talus bone, often associated with lateral malleolus or fibula fractures above the inferior tibiofibular joint.

Multiple fractures of the tibia, typically caused by high impact forces, potentially involving the talus or fibula. Requires internal or external fixation.

A joint between the talus and calcaneus bones allowing gliding and rotation, crucial for inversion of the foot.

Combination of the talocalcaneonavicular and calcaneocuboid joints, responsible for inversion and eversion movements of the foot.

Seven bones in the foot that form the ankle and arch. They include the talus, calcaneus, navicular, cuboid, and three cuneiform bones.

Five long bones in the foot connecting the tarsals to the phalanges. They are numbered 1-5 starting from the big toe.

14 small bones in each foot, forming the toes. Each toe (except the big toe) has three phalanges: proximal, middle, and distal.

A synovial joint formed by the talus of the foot and the tibia and fibula of the leg. It allows up-and-down movement of the foot (dorsi- and plantarflexion).

The two long bones in the lower leg. The tibia is thicker and weight-bearing; the fibula is thinner and provides stability.

The tibial nerve splits into two main branches: the medial plantar nerve and the lateral plantar nerve. These nerves supply sensation and movement to the foot.

The medial plantar nerve supplies sensation to the medial three and a half toes, including nail beds and tips. It also controls some muscles in the sole of the foot.

The lateral plantar nerve supplies sensation to the lateral one and a half toes, including nail beds and tips. It also controls some muscles in the sole of the foot.

The posterior tibial artery splits into two branches: the medial plantar artery and the lateral plantar artery. Both arteries supply blood to the foot.

The medial plantar artery, a smaller artery, supplies blood to the medial side of the big toe.

The lateral plantar artery, a larger artery, passes deep into the foot's muscles and forms the deep plantar arch. It joins the dorsalis pedis artery and supplies blood to the toes.

The deep plantar arch is created by the lateral plantar artery and is responsible for blood supply to the toes.

The midinguinal point is a landmark located halfway between the anterior superior iliac spine and the pubic symphysis (hip bones).

The pulse can be felt in the space between the tendons of extensor hallucis longus (EHL) and extensor digitorum longus (EDL) on the top (dorsal) of the foot, near the first metatarsal space.

The pulse can also be felt between the medial malleolus (inner ankle bone) and the heel.

A vein located on the lateral (outer) side of the foot, ascending posterior to the lateral malleolus, towards the popliteal vein.

A vein located on the medial (inner) side of the foot, ascending anterior to the medial malleolus, towards the femoral vein.

A major vein in the thigh that receives blood from the great saphenous vein, deep thigh veins, and perforating veins.

A vein in the back of the knee that receives blood from the deep veins of the leg and the small saphenous vein.

Veins located deep within the leg, accompanying arteries and draining into the popliteal vein. They include perforating veins.

A nerve that branches off from the sciatic nerve and travels along the back of the thigh towards the leg. It divides into the superficial fibular and deep fibular nerves.

A nerve that branches from the common fibular nerve and innervates the muscles that control ankle and foot dorsiflexion.

A nerve that branches from the common fibular nerve and innervates the muscles that control toe extension and foot inversion.

Pulse points in the lower limb that can be felt to check for blood flow. These points are located at the feet, ankles, and knees.

The network of blood vessels that deliver oxygen and nutrients to the foot and remove waste products.

The ability to locate and feel the rhythmic beat of blood in arteries of the lower limb by touch.

Using medical imaging techniques like X-rays, ultrasound, or MRI to visualize the structures of the foot and ankle.

The study of structures visible on the surface of the lower limb.

The ankle joint is formed by the talus of the foot and the distal ends of the tibia and fibula of the leg.

A fracture of the outer ankle bone (lateral malleolus) that occurs above the inferior tibiofibular joint, often associated with lateral talus movement.

The area on the fibula that connects with the talus, covered with hyaline cartilage. The joint is wider anteriorly than posteriorly, leading to greater stability when the foot is dorsiflexed.

Strong bands of tissue that connect the bones of the ankle, providing stability and preventing excessive movement. The lateral side has three main ligaments (anterior, posterior talofibular, and calcaneofibular), while the medial side has the strong deltoid ligament, composed of four parts.

Overstretching or tearing the ligaments on the lateral side of the ankle, usually caused by rolling the foot inwards. The anterior talofibular ligament is typically injured first, followed by the calcaneofibular, and in severe cases, the posterior talofibular ligaments.

A fracture involving both the medial and lateral malleoli (ankle bone projections) usually caused by forced foot eversion (turning outward). This results in avulsion fractures caused by ligament tension.

The bone in the foot that articulates with the fibula and tibia. The talus is essential for ankle movement; it is wider anteriorly than posteriorly.

Smooth and glossy cartilage that covers the ends of bones in joints. It reduces friction and allows for smooth movement.

The bony projection on the inner side of the ankle, formed by the tibia. It helps stabilize the ankle joint.

The bony projection on the outer side of the ankle, formed by the fibula. It helps stabilize the ankle joint.

Divides into the medial and lateral plantar arteries, supplying blood to the foot.

Located halfway between the anterior superior iliac spine and the pubic symphysis.

The pulse can be felt in the space between the tendons of extensor hallucis longus (EHL) and extensor digitorum longus (EDL) on the top (dorsal) of the foot, near the first metatarsal space.

Turning the sole of the foot inward, towards the midline of the body. Involves movement at the subtalar and midtarsal joints in the foot.

Turning the sole of the foot outward, away from the midline of the body. Involves movement at the subtalar and midtarsal joints in the foot.

Strong bands of tissue that hold the tendons of the extensor muscles in the anterior compartment of the leg in place, preventing them from slipping out of position. Located above the ankle.

The tibia and fibula are the two long bones in the lower leg. The tibia is thicker and weight-bearing, while the fibula is thinner and provides stability.

Overstretching or tearing of ligaments on the lateral side of the ankle, usually caused by rolling the foot inwards. The anterior talofibular ligament is typically injured first, followed by the calcaneofibular, and in severe cases, the posterior talofibular ligaments.

Moving the foot's top surface towards the leg, a movement that involves the anterior compartment of the leg and deep fibular nerve.

Moving the plantar surface of the foot away from the leg, a movement that involves the posterior compartment of the leg and tibial nerve.

Curvature along the length of the foot, spanning from heel to toes, supporting the arch. It's comprised of two parts: the medial and lateral parts.

The arch that runs across the foot, supporting the middle part of the foot where the tarsals meet the metatarsals, essentially forming the foot's width.

A thick band of connective tissue on the sole of the foot, responsible for transferring weight, protecting the foot's nerves and blood vessels, and helping maintain the arches.

The heel bone; the largest bone in the foot, serving as the foundation for the arches and bearing significant weight.

Strong ligament connecting the calcaneus to the navicular bone, supporting the medial longitudinal arch and acting as a shock absorber.

A location on the top of your foot where you can feel the pulse of the dorsalis pedis artery.

A location on the inside of your ankle where you can feel the pulse of the posterior tibial artery.
