What is the proximal tibiofibular joint?
The proximal tibiofibular joint (PTFJ) is a plane type synovial joint. The primary function of the PTFJ is dissipation of torsional stresses applied at the ankle and the lateral tibial bending moments besides a very significant tensile, rather than compressive weight bearing.
Where is the proximal tibiofibular joint located?
Anatomy. The proximal tibiofibular joint (PTFJ) is an arthrodial sliding joint located between the lateral tibial condyle and the fibular head. 1, 2 It is a synovial joint with hyaline cartilage articulation.
What movement occurs at the proximal tibiofibular joint?
As a plane synovial joint, the superior tibiofibular joint allows slight gliding movements. More specifically, this joint allows the accessory movement of anteroposterior gliding of the fibula against the tibia. These movements occur in a superior-inferior direction, and range to only a few degrees.
What two ligaments reinforce the proximal tibiofibular joint?
anterior talofibular ligament.
What is the proximal tibiofibular syndesmosis?
The proximal tibiofibular joint is the articulation between the fibula head and the inferior surface of the lateral condyle of the tibia. It is surrounded by a fibrous capsule and broad anterior and posterior ligaments. The joint is reinforced anteriorly by the biceps femoris tendon, inserting into the fibula head.
How many tibiofibular joints are there?
two joints
The tibiofibular joints are two joints of the leg, one superior and one inferior.
What ligaments attach to proximal fibula?
The function of the proximal end of the fibula is to provide points of attachment for minor supporting ligaments of the knee joint. There is the fibular collateral ligament that arises from the fibular apex and is surrounded by the tendon of biceps femoris.
Where is the tibiofibular syndesmosis located?
The tibiofibular syndesmosis is a complex fibrous joint composed of multiple ligaments and a broad fibrous interosseous membrane that spans between the tibia and fibula throughout the length of both bones.
What is the tibiofibular ligament?
The anterior tibiofibular ligament located deep within the leg, near the ankle. This ligament holds the two bones of the lower leg – the tibia and fibula – together. This is a very common place for people to injure themselves.
What type of joint is the Talofibular joint?
The superior tibiofibular joint is a plane type of synovial joint, which allows the involved bones to glide over one another to create movement. This joint is located between the flat articular facet on the fibular head and a similar articular facet situated posterolaterally on the lateral tibial condyle.
What structure is located on the proximal end of the fibula?
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. The fibula does not make up any part of the knee joint.
What is the distal tibiofibular syndesmosis?
Abstract. A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments. This definition also applies for the distal tibiofibular syndesmosis, which is a syndesmotic joint formed by two bones and four ligaments.
Where is the distal tibiofibular joint located?
The syndesmotic articulation of the distal tibiofibular joint occurs between the convex surface of the distal tip of the fibula and the concave fibular notch of the distal tibia. The stability of the syndesmosis is crucial to proper dynamic ankle and lower extremity function.
Why is the distal tibiofibular joint important?
Provide strong stabilization and dynamic support to the ankle mortise. Maintain the integrity between the distal tibia and fibula. Resist forces (axial, rotational, and translational) that attempt to separate the two bones.
