What bones are distal to the tibia and fibula?
The leg: Tibia and fibula in anatomical position with parts labeled. The tibia, or shin bone, spans the lower leg, articulating proximally with the femur and patella at the knee joint, and distally with the tarsal bones, to form the ankle joint.
What group of bones are proximal to the foot and distal to the tibia?
The talus is the lower ankle bone whose proximal end articulates with the distal ends of the tibia and fibula. Again, its articulation with the tibia bears more weight than it does with fibula. The calcaneus is the heel bone or the part of your foot you might want to karate kick with. The femur is not in the lower leg.
What bones are proximal to the metatarsals?
Each metatarsal consists of a head, shaft, and base. The proximal base articulates with the cuboid bones, and distally with the proximal phalanges, and each metatarsal also articulates laterally with adjacent metatarsals.
What bone is distal to the tibia?
Tarsal Bones Three areas of articulation form the ankle joint: The superomedial surface of the talus bone articulates with the medial malleolus of the tibia, the top of the talus articulates with the distal end of the tibia, and the lateral side of the talus articulates with the lateral malleolus of the fibula.
What is the main function of the tibia and fibula?
Structure and Function Unlike the tibia, the fibula is not a weight-bearing bone. Its main function is to combine with the tibia and provide stability to the ankle joint. The distal end of the fibula has several grooves for ligament attachments which then stabilize and provide leverage during the ankle movements.
How long does it take to recover from a broken tibia and fibula?
Recovery from a tibia-fibula fracture typically takes about three to six months. Your child may be able to heal faster by resting and not putting too much weight on their leg until the bone has healed.
What are the bones between your legs called?
The leg has two bones: the tibia and the fibula.
Which of the following is a non weight-bearing bone?
The fibula is a non-weight bearing bone that originates just below the lateral tibial plateau and extends distally to form the lateral malleolus, which is the portion of the fibula distal to the superior articular surface of the talus.
What type of bone is the metatarsals?
Long bones function to support the weight of the body and facilitate movement. Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).
Which of the five metatarsals is considered to be the most weight bearing?
The first metatarsal is larger than the others and most important for weight-bearing and balance; therefore, malunion or malalignment at this location is especially poorly tolerated. There are no interconnecting ligaments between the 1st and 2nd metatarsals, allowing for independent motion.
What is the main function of the tibia bone?
Structure and Function As the second-largest bone in the body, the tibia’s main function in the leg is to bear weight with the medial aspect of the tibia bearing the majority of the weight load.
How do the tibia and fibula work together?
The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The tibia is much thicker than the fibula. It is the main weight-bearing bone of the two. The fibula supports the tibia and helps stabilize the ankle and lower leg muscles.
Which is the distal end of the metatarsal bone?
The expanded distal end of each metatarsal is the head of the metatarsal bone. Each metatarsal bone articulates with the proximal phalanx of a toe to form a metatarsophalangeal joint . The heads of the metatarsal bones also rest on the ground and form the ball (anterior end) of the foot.
Is the fibula a proximal or distal bone?
The fibula is the slender bone located on the lateral side of the leg (see Figure 3). The fibula does not bear weight. It serves primarily for muscle attachments and thus is largely surrounded by muscles. Only the proximal and distal ends of the fibula can be palpated. The head of the fibula is the small, knob-like, proximal end of the fibula.
Which is larger the fibula or the tibia?
The tibia (shin bone) is the medial bone of the leg and is larger than the fibula, with which it is paired (Figure 3). The tibia is the main weight-bearing bone of the lower leg and the second longest bone of the body, after the femur.
What are the articulations of the metatarsals in the foot?
They have three or four articulations: 1 Proximally – tarsometatarsal joints – between the metatarsal bases and the tarsal bones. 2 Laterally – intermetatarsal joint (s) – between the metatarsal and the adjacent metatarsals. 3 Distally – metatarsophalangeal joint – between the metatarsal head and the proximal phalanx.
