What are the articulating surfaces of the proximal tibiofibular joint?
Articulating Surfaces The proximal tibiofibular joint is formed by an articulation between the head of the fibula and the lateral condyle of the tibia. It is a plane type synovial joint; where the bones to glide over one another to create movement.
Is the fibula connected to the knee?
Although it does not directly affect the knee’s movement, the fibula is connected via ligaments to the two ends of the tibia. It also helps to strengthen the tibia and provides support in the slight rotation of the knee. The most common fracture of the fibula occurs at the bottom of the bone near the ankle.
What does the proximal fibula articulate with?
Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. Distal tibiofibular joint – articulates with the fibular notch of the tibia. Ankle joint – articulates with the talus bone of the foot.
What are the articular surfaces of the knee?
Articular surfaces The roughened outer surfaces of the medial and lateral condyles are defined as medial and lateral epicondyles, respectively. Along the posterior aspect of the distal femur, there are paired rough elevations above the medial and lateral epicondyles known as the medial and lateral supracondylar ridges.
What is the difference between the proximal tibiofibular joint and the distal tibiofibular joint?
The tibiofibular joints are a set of articulations that unite the tibia and fibula. These two bones of the leg are connected via three junctions; The superior (proximal) tibiofibular joint – between the superior ends of tibia and fibula. The inferior (distal) tibiofibular joint – between their inferior ends.
What type of joint is found between the tibia and fibula?
syndesmosis
The distal joint between the tibia and fibula is an example of a syndesmosis. Cartiliginous Joints. Joints that unite bones with cartilage are called cartilaginous joints.
Where does fibula connect to knee?
The fibula is located on the lateral (outside) of the tibia, slightly posterior (to the back) and offsets a little below. The proximal (top) end of the fibula is articulated with the lateral condyle of the tibia, just below the knee. That is called the proximal tibiofibular joint.
Is fibula fracture serious?
All fibula breaks are serious and can leave you unable to fully walk, or perform standard daily activities without help, for weeks or months.
How is a proximal fibula fracture treated?
The general process for healing a fibula fracture is immobilization with a splint or cast for several weeks, after which you might get a walking boot to help you walk. Recovery time depends on factors such as: the severity of the injury and the presence of any other injury at the same time.
How does the knee work as a joint?
The knee is a hinge joint but it also has the ability to rotate slightly as it moves. The contraction of muscles at the front of the thigh (quadriceps) straightens the leg, while contraction of the muscles at the back of the thigh (hamstrings) allow the leg to bend at the knee.
What does articular surface mean?
Definition. The surface of a joint at which the ends of the bones meet. Supplement.
What happens to the fibula during dorsiflexion?
During dorsiflexion of the foot, the fibula externally rotates and consequentially slightly widens the interval between the tibia and fibula at the inferior tibiofibular joint. The joint is in a close packed position at maximum dorsiflexion of the foot, while it is loosely packed in plantar flexion.
Where are the articulations of the fibula surfaces?
1 Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. 2 Distal tibiofibular joint – articulates with the fibular notch of the tibia. 3 Ankle joint – articulates with the talus bone of the foot.
What happens to the proximal tibiofibular joint after amputation?
A result of below-knee amputations (BKAs) is abnormal motion that occurs about the proximal tibiofibular joint (PTFJ). While it is known that joint morphology may play a role in joint kinematics, this is not well understood with respect to the PTFJ.
What is the function of the fibula bone?
The fibula is a bone located within the lateral aspect of the leg. Its main function is to act as an attachment for muscles, and not as a weight-bearer. Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. Distal tibiofibular joint – articulates with the fibular notch of the tibia.
What are the three articulations of the foot?
It has three main articulations: Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. Distal tibiofibular joint – articulates with the fibular notch of the tibia. Ankle joint – articulates with the talus bone of the foot.
