Bifurcate ligament. The bifurcate ligament consists of two parts: the calcaneonavicular and calcaneocuboid ligaments. The calcaneonavicular ligament (a.k.a. calcaneonavicular part of bifurcate ligament) helps to support the talonavicular joint laterally.
Where is the talonavicular ligament located?
The broad and thin talonavicular ligament is located between the plantar calcaneonavicular and calcaneonavicular ligaments. It extends between the superior, or dorsal surface of the neck of talus and the dorsal surface of the talus. The talonavicular ligament reinforces the talonavicular joint dorsally.
What is the long plantar ligament?
The long plantar ligament lies superficial to the plantar calcaneocuboid ligament and the tendon of fibularis longus muscle on the plantar aspect of the foot. It runs from the anterior calcaneal tubercle to the ridge and tuberosity of cuboid bone, attaching to both of them. It also sends some superficial fibers towards the lateral four metacarpal bases. Therefore, the long plantar ligament spans almost the entire length of the lateral plantar aspect of the foot, reinforcing the plantar aspects of all the respective lateral foot joints, including the calcaneocuboid joint. It also prevents excessive depression of the lateral longitudinal arch of the foot during weight bearing.
What is the function of the plantar calcaneocuboid ligament?
The function of the plantar calcaneocuboid ligament is to strengthen the inferior border of the joint capsule of the calcaneocuboid joint. It also supports the lateral longitudinal arch of the foot during weight loading.
Which bone is most commonly fractured?

What are the tarsal bones of the foot?
The tarsal bones of the foot are organised into three rows: proximal, intermediate, and distal. Proximal Group (Hindfoot) The proximal tarsal bones are the talus and the calcaneus. These comprise the hindfoot, forming the bony framework around the proximal ankle and heel.
What are the bones of the foot?
Bones of the Foot: Tarsals, Metatarsals and Phalanges. The bones of the foot provide mechanical support for the soft tissues; helping the foot withstand the weight of the body whilst standing and in motion. Tarsals – a set of seven irregularly shaped bones. They are situated proximally in the foot in the ankle area.
Where are the tarsals located?
They can be divided into three groups: Tarsals – a set of seven irregularly shaped bones. They are situated proximally in the foot in the ankle area. Metatarsals – connect the phalanges to the tarsals. There are five in number – one for each digit. Phalanges – the bones of the toes.
How many phalanges are there in the toe?
Each toe has three phalanges – proximal, intermediate, and distal (except the big toe, which only has two phalanges). The foot can also be divided up into three regions: (i) Hindfoot – talus and calcaneus; (ii) Midfoot – navicular, cuboid, and cuneiforms; and (iii) Forefoot – metatarsals and phalanges.
What are the three regions of the foot?
The foot can also be divided up into three regions: (i) Hindfoot – talus and calcaneus; (ii) Midfoot – navicular, cuboid, and cuneiforms; and (iii) Forefoot – metatarsals and phalanges. In this article, we shall look at the anatomy of the bones of the foot – their bony landmarks, articulations, and clinical correlations.

Talar fractures most commonly occur in the neck of the talus (50%) but can occur in the talar body or lateral process, with those in the talar head being the least common.
What bones are in the midfoot?
Midfoot: The midfoot is made up of five of the seven tarsal bones: navicular, cuboid, and medial, middle, and lateral cuneiforms. The junction between the hind and midfoot is termed the Chopart's joint, which includes the talonavicular and calcaneocuboid joints.
Where are MTP joints formed?

Dorsal ligaments. The dorsal ligaments are strong, flat bands. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
What is the subtalar joint?
The subtalar joint (talocalcaneal joint) is anatomically described as the articulation formed between posterior articular surfaces of two tarsal bones; the talus and calcaneus. In the literature, this joint is also referred to as the anatomical subtalar joint or subtalar joint proper .
Where is the interosseous talocalcaneal ligament located?
The interosseous talocalcaneal ligament is composed of two short and broad fibrous bands located in the tarsal sinus. The deep extension of the inferior extensor retinaculum is situated between these bands of the interosseous ligament.
Where is the tarsal sinus?
The tarsal sinus is a narrow passageway located immediately anterior to the subtalar joint, between the talus and calcaneus. Inside the tarsal sinus, the joint capsules of the subtalar and talocalcaneonavicular joints meet and form the talocalcaneal interosseous ligament.
What is sinus tarsi syndrome?
Sinus tarsi syndrome is a painful clinical condition caused by excessive motions of the subtalar joint. It is typically seen in dancers, runners, volleyball and basketball players. The persistent anterolateral ankle discomfort that occurs in athletes can result in subtalar joint synovitis and infiltration of fibrous tissue into the sinus tarsi space. The diagnosis is usually established by the physical examination that reveals a localized ankle discomfort to the sinus tarsi space and feelings of instability with pronation and supination movements of the subtalar joint. In treatment, physical therapy in combination with anti-inflammatory medication is usually efficient.
