The weight-bearing bones of the foot and lower leg are especially vulnerable to stress fractures because of the repetitive forces they must absorb during activities like walking, running, and jumping. Foot and Ankle 24.1 Anatomy Gail A. Shafer-Crane William M. Falls SKELETAL Three bones participate in the ankle joint: the tibia and fibula of the leg, and the talus bone, a tarsal bone. It functions as a rigid structure for weight bearing and it can also function as a flexible structure to conform to uneven terrain. The talar head interacts with the navicular bone to form the talo-navicular joint. Rolling your ankle can cause a break in the knobby bumps at the end of the tibia and fibula.

Cuboid-metatarsal joint for the fourth and fifth metatarsal. At this end, the calcaneus connects to the cuboid bone to form the calcaneal-cuboid joint. These joints are very flexible, allowing the metatarsal heads to continuously support the weight of the body, as the foot moves from heel to toe. This is the site where the posterior tibial tendon anchors into the bone. The fibula accepts the remaining 15%; its main role is to serve as the lateral wall of the ankle mortise (Figure 4). These series of connections allow the foot to rotate smoothly around the talus, as when you roll your ankle in a circle. Mid-foot – The midfoot begins with the calcaneal-cuboid joint, and essentially ends where the metatarsals begin. The metatarsals are numbered 1-5, starting on the inside and leading outward (from big toe to smallest). The second metatarsal may be overly long in some individuals, predisposing them to 2nd metatarsalgia. The calcaneal-cuboid joint attaches the heel bone to the cuboid. The largest bone of the foot, the calcaneus, forms what is commonly referred to as the heel. The calcaneus is something like an oddly shaped egg; hard cortical bone on the outside covers softer cancellous bone on the inside. This positioning allows the foot to cope with uneven terrain because it allows a little more flexibility from side to side. They will also ask about how the injury occurred and perform an examination of the affected area. The hind foot consists of the Talus bone or ankle bone and the calcaneous bone or heel bone. The phalanges make up the bones of the toes. There are three different cuneiform bones present side-by-side in the midfoot. The Metatarsus 3.

The midfoot is a pyramid-like collection of bones that form the arches of the feet. The middle phalanx meets the “distal” phalanx at the distal interphalangeal joint. The long part of the metatarsal bone is known as the metatarsal “shaft”, and the thick end of the bone nearest the toes is known as the metatarsal “head” (the metatarsal neck lies between the shaft and head). It is important that all these symptoms are … An imbalance in the tendons pulling across these small joints of the toes will lead to deformity of the toe, such as a clawtoe.

The bones that comprise the fore-foot are those that are last to leave the ground during walking. The tibia and fibula are held together by a tough layer of connective tissue, known as the Interosseous Membrane. This joint allows for the potential to have significant motion between the hindfoot and the midfoot, depending on the position the hindfoot is in. Each metatarsal is a long bone that joins with the mid-foot at its base, a joint called the tarsal-metatarsal joint, or Lisfranc joint. Today 's Points.

The talus is covered by so much cartilage because it connects so many different bones. It allows a little wiggle from side to side, but most of the rest of the movement comes from the foot joints. Functionally, it is a hinge type joint, permitting dorsiflexion and plantarflexion of the foot.. Unfortunately, the talus has relatively poor blood supply, which means that injuries to this bone take greater time to heal than might be the case with other bones.

The talar neck is located between the body and head of the talus, and is remarkable because it is one of the few areas of the talus not covered with cartilage, and is one of the few places that blood can flow to in the talus. Second, the phalanges connect to the foot at the metatarsal heads at a joint called the metatarsal-phalangeal joint. The Phalanges(bones of the toes) There are 7 tarsal bones, 5 metatarsal bones and 14phalanges. On the inner side (closest to the middle of the foot), there is a piece of bone that juts out, which is called the navicular tuberosity. Bone Tumors of the Foot and Ankle Lawrence S. Osher Bryan D.

The talus holds the ankle together by connecting to the lower leg with a ball joint, connecting to the calcaneous on the underside through the subtalar joint, and by helping connect the back part of the foot (hindfoot) to the midfoot via the talo-navicular joint. Foot Muscles The tibia widens distally, forming the medial malleolus, while the distal fibula also enlarges to form the lateral malleolus. Actions. There are three protrusions on the top surface of the calcaneus (the posterior, middle, and anterior “facets”) that allow the talus to sit on top of the calcaneus, forming the sub-talar joint. The anterior talo-fibular ligament is often thought of as the “ankle sprain ligament”, because it is the one that is most often damaged when the ankle is rolled. It is formed by the bones of the leg (tibia and fibula) and the foot (talus). These are known as the proximal phalanx (closest to the ankle) and the distal phalanx (farthest from the ankle).The four “lesser toes” (toes 2-5) all have three phalanges. Total Points. An ankle sprain is a ligament injury in the foot, without dislocation or a fracture. All three cuneiforms line up in a row and articulate with the navicular, forming the naviculo-cuneiform joint.

Primarily, it functions to transmit your body’s weight to the foot through the talocalcaneonavicular joint. One of us! Like the talus, the navicular has a poor blood supply. In general, the first three metatarsals are more rigidly held in place than the last two, although in some individuals there is increased motion associated with the 1st metatarsal where it joins the midfoot (at the 1st tarso-metatarsal joint), and this increased motion may predispose them to develop a bunion. Today's Rank--0. An easy example of such a bone is the kneecap (patella). Though the tibia (commonly called the shin bone) is not a part of the foot, it plays an important role. X-RAYS: X-rays can show if the ankle bone has been broken and how many pieces of broken bone there are. The foot and ankle provide various important functions which includes: 1. supporting body weight, 2. … While it has several more joints than the hind-foot, it still possesses little mobility.
