What is fibula fracture?
A fibular fracture is a break to your fibula caused by a forceful impact that results in injury. It can also happen when there’s more pressure or stress on the bone than it can handle. The fibula is a bone in the lower leg stretching from the knee to the ankle and visible from the outside.
What’s a tibia fracture?
A tibia fracture refers to any crack or breaks in the tibia bone. The tibia is one of two bones that make up the lower leg, the other being the fibula. The tibia is the larger of these two bones. The tibia plays a key role in body mechanics, as it is: the larger of the two lower leg bones.
Which type of fracture occurs in the ankle and affects both the tibia and fibula?
A pilon fracture is a type of break that occurs at the bottom of the tibia (shinbone) and involves the weight-bearing surface of the ankle joint. With this type of injury, the other bone in the lower leg, the fibula, is frequently broken as well.
What is a distal fibula fracture?
Synopsis. Distal fibula fracture, the most common type of ankle fracture, is an isolated malleolar fracture (70% or greater); the majority of these are lateral malleolus fractures. Distal fibula fractures can affect adult patient of any age as well as children.
Where is fibula and tibia?
Tibia and fibula are the two long bones located in the lower leg. 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.
What is the end of the tibia called?
medial malleolus
At the distal end of the tibia, the bone has changed shaped from triangular in cross section to rectangular in cross section. The medial surface of the distal end features a bony extension called the medial malleolus. It articulates with the talus within the ankle joint.
What causes tibia and fibula fracture?
Tibia-fibula fractures are usually a result of a fall or hard blow to the leg that puts too much force on the bone. Common causes include: sudden twist if the leg is stiff or planted in place, which is common in football, hockey, and basketball.
What is the distal aspect of the fibula?
The distal end of the fibula forms the lateral malleolus of the lower limb. This is a bony projection noted on the lateral surface of the ankle, which is complementary to another bony projection on the medial aspect of the ankle called the medial malleolus (formed by the tibia).
What structure connects the tibia and fibula?
A strong fibrous structure, the interosseous membrane or ligament (figure 2), connects the tibia and fibula along the length of the two bones. Proximally, this structure, reinforced by strong anterior and posterior ligaments, forms a synovial joint, the proximal tibiofibular articulation (picture 4).
What is the main difference between a fracture that is classified as an ankle fracture and one classified as a pilon fracture?
Unlike common ankle fractures, pilon fractures are very complex and involve the articular surface and tibial shaft. These fractures are characterized by compression fractures and articular comminution of the distal metaphysis [10].
What are the three major landmarks on the tibia?
Like other long bones, there are three parts of the tibia: proximal, shaft, and distal. The proximal part participates in the knee joint, whereas the distal part contributes to the ankle joint.
