Is the Tibiotalar joint in the ankle?
The ankle joint (also known as the tibiotalar joint or talocrural joint) forms the articulation between the foot and the leg. It is a primary hinge synovial joint lined with hyaline cartilage.
Where is Tibiotalar?
ankleThe anterior inferior ligament and the anterior ligament of the lateral malleolus are also known as the anterior tibiotalar ligament. It is located in the ankle. This ligament is made up of a triangular band of fibers that broadens as it descends.
What motions happen at the Tibiotalar joint?
Motion of the ankle occurs primarily in the sagittal plane, with plantar- and dorsiflexion occurring predominantly at the tibiotalar joint. Several studies have indicated an overall ROM in the sagittal plane of between 65 and 75°, moving from 10 to 20° of dorsiflexion through to 40–55° of plantarflexion.
What are the two joints of the ankle?
The true ankle joint, which is composed of three bones: the tibia, the larger and stronger of the two lower leg bones, which forms the inside part of the of the ankle. the fibula, the smaller bone of the lower leg, which forms the outside part of the ankle.
What is Tibiotalar?

What type of joint is the Tibiotalar?
The tibiotalar joint is a diarthrosis and is covered by a thin capsule attaching superiorly to the tibia, and the malleoli, and inferiorly to the talus. Stability is given to the joint through three groups of ligaments.
What is Tibiotalar osteoarthritis?
Ankle arthritis is a clinical condition in which the joint that connects the foot to the leg, known as the tibiotalar or ankle joint, has damaged or worn out cartilage. There are three bones involved in this joint: the tibia, the fibula and the talus. The arthritis can involve any or all of these bones.
What is a small Tibiotalar joint effusion?
Joint effusion (a swollen joint) happens when extra fluids flood the tissues around your joint. The fluids make your joint look larger and puffier compared to your other joints.
What does it mean when your ankles ache?
The most common causes include injury, arthritis and normal wear and tear. Depending on the cause, you may feel pain or stiffness anywhere around the ankle. Your ankle may also swell, and you may not be able to put any weight on it. Usually, ankle pain gets better with rest, ice and over-the-counter pain medications.
What is the most powerful movement at the ankle joint?
The PTFL is the strongest of the three portions of the lateral ankle. It runs almost horizontally from the fossa in the inner aspect of the tip of the lateral malleolus to the posterior tubercle of the talus. The PTFL inhibits external rotation with the ankle in dorsiflexion.
What is your ankle joint called?
Talocrural jointThe ankle joint, or Talocrural joint, is a large synovial joint. It is a hinge joint that allows plantarflexion and dorsiflexion, moving the foot up and down.
What is the bone under your ankle called?
It is the coming together of three bones: the fibula of the shin on the outside of the ankle; the tibia, also of the shin, on the inside of the ankle and that talus bone underneath them. It is responsible for the up and down movement of the foot. The subtalar joint is the second part of the ankle.
Which ligament is the only direct soft tissue connection between the tibiotalar and subtalar joint?
They are the anterior and posterior talofibular ligaments and the calcaneofibular ligament. The lateral ligaments are frequently injured during inversion injuries. The calcaneofibular ligament is the only direct soft tissue connection between the tibiotalar and subtalar joint. Lateral collateral ligament.
What nerve is the tibial nerve?
tibial nerve, deep peroneal nerve. Vasculature. anterior and posterior tibial arteries, peroneal artery. Range of Motion. 10° to 20° of dorsiflexion, 40° to 55° of plantarflexion. The tibiotalar joint, also known as the ankle joint or talocrural joint, is formed by the junction between the distal tibia and fibula and the talus.
Which ligaments provide stability?
There are three groups of ligaments that provide stability. Tibiofibular syndemosis. This limits motion between the tibia and fibula. There are three parts - the anterior tibiofibular ligament, the posterior tibiofibular ligament, and the interosseous tibiofibular ligament.
Which ligaments protect against inversion of the joint limiting varus stresses and reduce rotation?
It is fan shaped and has anterior and posterior tibiotalar ligaments, the tibionavicular ligament, and the tibiocalcaneal ligament. Lateral collateral ligaments. These protect against inversion of the joint limiting varus stresses and reduce rotation.
What plane is the axis of the sagittal joint?
The axis is approximately at 10° with the horizontal medial-lateral axis in the coronal plane, and approximately at 6° with the horizontal medial-lateral axis in the transverse plane. This obliquity is minor and so in most situations the joint is considered to function in the sagittal plane alone.
Which joint is most stable in a position of dorsiflexion?
The talus is widest anteriorly, leading to the joint being most stable in a position of dorsiflexion, called a "close packed" position. Stability is provided by the joint geometry (especially in the stance phase of the gait) and the soft tissue structures. The joint has a thin capsule that attaches to the tibia, malleoli, and talus.
What is the range of normal plantarflexion?
There is a wide range of normal. With goniometric measurements the range is 10° to 20° of dorsiflexion and 40° to 55° of plantarflexion. The joints of the midfoot contribute 10% to 41% of plantarflexion from neutral to 30° plantarflexion.
Where is the anterior tibiotalar ligament located?
The anterior inferior ligament and the anterior ligament of the lateral malleolus are also known as the anterior tibiotalar ligament. It is located in the ankle.
Where is the ligament located?
It is located in the ankle. This ligament is made up of a triangular band of fibers that broadens as it descends. This ligament extends laterally (away from the midline of the body) and downwards between the tibia (shinbone) and fibula (calf bone). The ligament passes in front of and across the fibular malleolus ...
Where is the superior tibiofibular joint located?
The superior tibiofibular joint is an articulation between articular facets on the proximal ends of the tibia and fibula respectively. The tibial articular facet is located on the lateral tibial condyle and it faces posteriorly, inferiorly and laterally.
What are the superior and inferior tibiofibular joints?
Superior and inferior tibiofibular joints (Articulatio tibiofibularis superior et inferior) The tibiofibular joints are a set of articulations that unite the tibia and fibula. These two bones of the leg are connected via three junctions; The superior (proximal) tibiofibular joint - between the superior ends of tibia and fibula.
What is the interosseous ligament?
The articular surfaces of the distal tibiofibular joint are held together by the interosseous ligament, and the anterior, posterior and transverse tibiofibular ligaments. The interosseous tibiofibular ligament connects the facing surfaces of the bones and it is continuous with the interosseous membrane of the leg.
What are the joints of the leg?
Ligaments and joint capsule 1 The interosseous tibiofibular ligament connects the facing surfaces of the bones and it is continuous with the interosseous membrane of the leg. It strongly connects the bones and it is the principal stabilizer of this joint. 2 The anterior and posterior tibiofibular ligaments extend between the anterior and posterior surfaces of the tibia and fibula, respectively. They both course inferiorly and laterally, with the posterior ligament being thicker and wider than the anterior. These ligaments cover the trochlear surface of talus interchangeably during the foot movements; the anterior during dorsiflexion and the posterior during the plantar flexion of the foot. 3 The inferior transverse ligament is found deep to the posterior tibiofibular ligament. It is considered by many authors to be the deep part of the posterior tibiofibular ligament. It is made of yellow ligamentous fibers which contain much more elastic fibers than the white ligaments which are seen in most of the body’s joints. This feature makes this ligament far more stretchy than other ligaments of this joint.
What is the membrane that surrounds the capsule of the knee?
The internal surface of the capsule is lined by a synovial membrane which is sometimes continuous with that of the knee joint. In this case, the distal prolongation of the knee joint cavity called the popliteal bursa communicates with the tibiofibular joint through an aperture on the upper part of its capsule.
How many fascicles are there in the fibular head?
The ligament consists of two to three fascicles that arise from the anterior aspect of the fibular head. The fascicles then take an oblique, superomedial, course and attach to the anterior surface of the lateral tibial condyle. The posterior ligament of fibular head is also short and wide in structure.
Which nerve innervates the superior tibiofibular joint?
Innervation. The superior tibiofibular joint is innervated by the common fibular nerve (recurrent branch) and the nerve to popliteus muscle. The former is a branch of the sciatic nerve, while the latter stems from the tibial nerve.
What joint is the closest to the ankle?
There are many small joints near the ankle joint that may mimic ankle arthritis. The closest major joint is the subtalar joint. Because the joints are small and close together and they may be affected by similar activities, it may take specific examination and x-rays to determine which joint is causing the symptoms.
What bones are affected by arthritis in the ankle?
Ankle arthritis may affect any of the three bones that make up the ankle joint: the tibia, the fibula and the talus. The talus is a small but important bone that connects the foot to the leg.

How to manage ankle arthritis pain?
Pain and fatigue. Pain from ankle arthritis is managed with weight reduction, activity modification, analgesic medications, bracing and sometimes surgery. The steps that reduce pain may also reduce the sense of fatigue and accompanies the pain.
How to treat arthritis in ankle?
There are many steps in the treatment of arthritis. The first step is weight reduction and activity modification. Weight reduction is helpful because excess weight causes a magnified increase in weight on the small ankle joint. Activity modification is helpful if specific activities cause the symptoms. If these steps are not helpful, over-the-counter analgesic medications such as acetaminophen are used. The next step is bracing and then use of non-steroidal anti-inflammatory medications . When these are no longer successful, surgery may be indicated. Surgical treatment options range from minimally invasive surgery up to and including an ankle replacement or ankle arthrodesis.
What test is used to diagnose ankle arthritis?
When ankle arthritis is a part of a systemic condition, blood tests may be used for its diagnosis. Occasionally, a bone scan may be useful. Other tests involving injection of solutions into joints may be employed at times.
Can arthritis affect the ankle?
It is not widely known that arthritis can affect the ankle. The ankle is much less likely to be involved with arthritis than the hip or knee. The ankle is less often involved in osteoarthritis. However, arthritis does affect the ankle. It is likely to be involved in inflammatory arthritis such as rheumatoid arthritis.
What is the subtalar joint?
The subtalar joint, also known as the talocalcaneal joint, is a compound joint positioned directly below the ankle joint. 1 It is comprised of the calcaneus (heel bone) and a column-shaped bone called the talus. The subtalar joint is vital to movement as it helps to readjust the lateral (side-to-side) position of your foot as you navigate uneven ...
What is the function of the subtalar joint?
Function of the Subtalar Joint. Walking is a sophisticated function for which we give little thought . From the perspective of the ankle and foot, this requires three distinct actions: We need to be able to roll the foot away from the midline of the body ( supination) and toward the midline of the body (pronation).
What are the facets of the bones?
The facets are known as the anterior subtalar joint (ASTJ), the medial subtalar joint (MSLJ), and the posterior subtalar joint (PSTJ). The bones are held in placed by strong but flexible connective tissues called ligaments. The main ligament is called the interosseous talocalcaneal ligament , which runs along a groove between the bones called ...
What test is used to determine if a patient has a subtalar joint infection?
If a specific infection is suspected, a bacterial culture or antibody-based viral blood test may be performed. Tests can also be used to differentiate subtalar joint disorders from other conditions that cause pain or inflammation in the ankle and heel area.
Why is the subtalar joint important?
The subtalar joint is vital to movement as it helps to readjust the lateral (side-to-side) position of your foot as you navigate uneven or shifting terrain. Without the subtalar joint, you would be unable to run, jump, walk, or move with any precision.
Which joint plays no role in dorsal or plantar flexion?
Supination involves eversion as the arch is lifted and the midfoot rolls to the side. The subtalar joint plays no role in either dorsal or plantar flexion.
What is the name of the joint that is affected by gout?
Gout is a type of arthritis that commonly affects the first metatarsophalangeal joint (the big toe), but can also cause inflammation and pain in the subtalar joint. 2. Juvenile idiopathic arthritis is a type of pediatric arthritis with no known cause in which the subtalar joint is often the first joint affected.
