What type of joint is the tibiofibular?

What type of joint is the tibiofibular?

plane type synovial 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.

What movements occur at the 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 is the tibiofibular syndesmosis?

The tibiofibular syndesmosis is a fibrous joint essential for ankle stability, whence the classical comparison with a mortise. Syndesmosis lesions are quite frequent in ankle trauma. This is a key element in ankle stability and lesions may cause pain or instability and, in the longer term, osteoarthritis.

What is the name of the ligament that connects the tibiofibular joint?

Ligaments & Interosseus membrane

LIGAMENTS DESCRIPTION ROLE / FUNCTION
Transverse ligament or the Transverse tibiofibular ligament (TTFL) Cone shaped Also known as the Deep component of the PTIFL Forms a true labrum Provides talocrural joint stability. Prevents Posterior translation

Where is tibiofibular ligament?

The anterior-inferior tibiofibular ligament originates from the longitudinal tubercle on the anterior surface of the lateral malleolus and attaches on the anterolateral tubercle of the tibia (Chaput fragment).

What is the inferior tibiofibular ligament?

The anterior inferior tibiofibular ligament is a flat, strong ligament (Figure ​ 1). It originates from the longitudinal tubercle on the anterior aspect of the lateral malleolus, and the fibers course superiorly and medially, attaching on the anterolateral tubercle of the tibia.

What is the ball on your ankle called?

A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia.

Where is distal tibiofibular syndesmosis?

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 syndesmotic?

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 anterior inferior tibiofibular ligament?

lateral malleolus
The anterior inferior tibiofibular ligament is a flat, strong ligament (Figure ​ 1). It originates from the longitudinal tubercle on the anterior aspect of the lateral malleolus, and the fibers course superiorly and medially, attaching on the anterolateral tubercle of the tibia.
