Tendons Of Leg And Foot

Posted on April 14, 2024 by admin

Tendons are thick bands of tissue that connect muscles to bone. When a muscle contracts, the tendon pulls on the bone causing the joint to move. There are a number of tendons located in the foot and ankle all responsible for different ankle, foot and toe movements. Tendons also help to provide stability around the foot and ankle.

Let’s start by looking at the lateral ankle tendons found on the outer side of the ankle and foot, the peroneal tendons. There are two peroneal tendons, one from the peroneal longus muscle the other from peroneal brevis. The peroneal tendons run down together behind the outer side of the ankle and then split before attaching to different parts of the foot. The peroneal tendons and their respective muscles help to pull the foot down into plantarflexion and outwards into eversion. Functionally, they are very important for providing stability when running, particularly on uneven ground.

There are a number of foot and ankle tendons that pass around the inner side of the ankle producing various foot movements. The tibialis anterior muscle originates from the outer side of the tibia and passes down the front of the shin. The muscle turns into tendon about two thirds of the way down the shin and travels across the front of the ankle joint to the inner side of the foot underneath the medial foot arch. Tibialis anterior is a strong ankle tendon that pulls the foot up into dorsiflexion. Functionally, it is really important when walking as it lifts the foot up to prevent it catching on the ground as the leg swings forwards and controls foot placement once the heel strikes the ground. It also works with other medial ankle tendons to turn the foot inwards into inversion.

Tibialis posterior is the deepest muscle on the back of the leg. The tendon passes behind the inner ankle bone (medial malleolus) and underneath the foot attaching to the tarsal bones. The tibialis posterior tendon is the main invertor of the foot and also helps the calf muscles to plantarflex the foot. It plays an important role in supporting the medial arch and functionally controls the position of the foot during walking and running.

Foot tendonitis is inflammation or irritation of a tendon in your foot. Overuse usually causes foot tendonitis, but it can also be the result of an injury. Your feet contain many tendons. Tendonitis can affect any of them, but the most common include: Achilles tendonitis, Extensor tendonitis, Peroneal tendonitis, Posterior tibial tendonitis. Achilles tendonitis is the most common type of foot tendonitis. Studies suggest it affects anywhere from 1% to 9% of elite and recreational athletes..

Bones Of The Foot And Ankle

Posted on March 28, 2024 by admin

The foot and ankle form a complex system which consists of 28 bones, 33 joints, 112 ligaments, controlled by 13 extrinsic and 21 intrinsic muscles?. The foot is subdivided into the rearfoot, midfoot, and forefoot?.

Ankle Anatomy

The ankle joint, also known as the talocrural joint, allows dorsiflexion and plantar flexion of the foot. It is made up of three joints: upper ankle joint (tibiotarsal), talocalcaneonavicular, and subtalar joints. The last two together are called the lower ankle joint. The upper ankle joint is formed by the inferior surfaces of tibia and fibula, and the superior surface of talus. The lower ankle joint is formed by the talus, calcaneus, and navicular bone.

Bones of the Foot

The foot begins at the lower end of the tibia and fibula, the two bones of the lower leg. At the base of those, a grouping of bones form the tarsals, which make up the ankle and upper portion of the foot. The bones of the foot are organized into the tarsal bones, metatarsal bones, and phalanges.

1. Tarsal Bones: These include the talus and calcaneus, which form the ankle joint and the heel, and the navicular, cuboid, and three cuneiforms, which form the arch of the foot.
2. Metatarsal Bones: These are the long bones that connect the tarsals to the toes.
3. Phalanges: These are the small bones that form the toes. The great toe consists of two phalanges (proximal, distal), while the remaining four toes have three phalanges (proximal, middle, distal).

Joints of the Foot

The foot has several joints, including intertarsal, tarsometatarsal, metatarsophalangeal, and interphalangeal joints. The great toe has one interphalangeal joint, while the other four toes have two (proximal, distal) interphalangeal joints.

Muscles of the Foot

The foot has several muscles that allow movements like foot inversion, foot eversion, toe flexion, toe extension, toe abduction, and toe adduction. These include dorsal muscles (extensor digitorum brevis, extensor hallucis brevis), lateral plantar muscles (abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimi), central plantar muscles (flexor digitorum brevis, quadratus plantae, lumbricals, plantar interossei, dorsal interossei), and medial plantar muscles (abductor hallucis, adductor hallucis, flexor hallucis brevis).

In conclusion, the foot and ankle’s complex structure, consisting of numerous bones, joints, and muscles, allows for a wide range of movements and provides the necessary stability and flexibility for various activities such as walking, running, and jumping..

Muscles In The Foot Image

Posted on December 18, 2022 by admin

The muscles of the foot can be split into two groups, the extrinsic and intrinsic muscles. The extrinsic foot muscles are found in the lower leg and act to dorsiflex, plantarflex, invert and evert the foot. The intrinsic foot muscles are entirely contained within it, and primarily act to move the toes.
The 20-plus muscles in the foot help enable movement, while also giving the foot its shape. Like the fingers, the toes have flexor and extensor muscles that power their movement and play a large role in balance. However, many muscles that power the foot’s movement originate as high up as the back of the knee.

Foot Ligaments Image

Posted on June 7, 2022 by admin

Because there are so many bones in the foot, there are also numerous ligaments connecting them. Some of the main ligaments in the foot are: Plantar fascia ligament: Runs underneath your foot from the heel to the base of your toes.
While the bones in the foot can fracture and the foot’s muscles can experience strains, one of the more common and potentially serious foot injuries are torn ligaments. Ligaments are the strong and flexible tissues that hold the bones throughout your body together; when a ligament tears, the resulting injury is often referred to as a sprain.
