The calcaneofibular ligament (Figure 10) is also on the lateral side of the ankle. It starts at the tip of the fibula and runs along the lateral aspect of the ankle and into the calcaneus. It too resists inversion, but more when the ankle is dorsiflexed. Posterior TaloFibular Ligament
Lateral cuneiform. Some people may be born with an extra navicular bone (accessory navicular) beside the regular navicular bone, on the inside of the foot. This is a normal anatomical variation seen in around 2.5% of the entire population of the US. Metatarsal Bones.
The cuboid is on the lateral side of the foot (outer foot) and sits in front of the calcaneus. The navicular is on the medial (inner) side of the foot, between the talus and the cuneiform bones in front. The navicular forms joints with four bones: the talus and the three cuneiforms.
The lateral arch is the flatter of the two longitudinal arches, and lies on the ground in the standing position. It is formed by the calcaneus, cuboid and 4th and 5th metatarsal bones. It is supported by: Muscular support: Fibularis longus, flexor digitorum longus, and the intrinsic foot muscles.
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.
Foot Anatomy. The foot contains 26 bones, 33 joints, and over 100 tendons, muscles, and ligaments. This may sound like overkill for a flat structure that supports your weight, but you may not realize how much work your foot does!
This article will discuss these joints, detailing their articular surfaces, the ligaments that stabilize them, and the muscles that produce movement at these joints. This will be followed by clinically relevant notes of common pathologic conditions affecting these structures.
Oblique Head: Bases of the 2nd, 3rd, and 4th Metatarsals. Transverse Head: Plantar Ligaments of the Metatarsophalangeal Joints. Lateral Side of the Base of the Proximal phalanx of the Great Toe. Deep Branch of Lateral Plantar Nerve. Adducts the Great Toe and Assists in Maintaining the Transverse Arch of the Foot.
Introduction. Human feet allow bipedal locomotion, [1] and they are an essential sensory structure for postural control. [2] . The foot structure is complex, consisting of many bones, joints, ligaments and muscles. The foot is divided into three parts: rearfoot, midfoot, and forefoot.
Cuboid Bone: Found on the lateral side, it articulates with the calcaneus and the fourth and fifth metatarsals. Cuneiform Bones: These three bones (medial, intermediate, and lateral) are situated between the navicular and the first three metatarsals. The Hindfoot. The hindfoot consists of two primary bones: the talus and the calcaneus.
