What is the distal tibiofibular syndesmosis?
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.
What is tibiofibular Synostosis?
Tibiofibular synostosis is a rare condition of union between tibia and fibula. Etiologically, it may be congenital, acquired (traumatic, iatrogenic, therapeutic types) or idiopathic [8].
Where is the tibiofibular ligament?
The anterior ligament of the lateral malleolus (anterior tibiofibular ligament or anterior inferior ligament) is a flat, trapezoidal band of fibers, broader below than above, which extends obliquely downward and lateralward between the adjacent margins of the tibia and fibula, on the front aspect of the syndesmosis.
What structures are in the distal tibiofibular syndesmosis?
The osseous portion of the distal tibiofibular syndesmosis consists of the tibia and fibula, and the four connecting ligaments include the anterior inferior tibiofibular ligament, posterior inferior tibiofibular ligament, inferior transverse ligament, and the interosseus ligament.
What is the function of the syndesmosis complex at the distal tibiofibular joint?
Function. The function of syndesmosis ligament complex: Provide strong stabilization and dynamic support to the ankle mortise. Maintain the integrity between the distal tibia and fibula.
What type of joint is distal tibiofibular?
A syndesmosis is a complex fibrous joint between two bones and connected by ligaments and a strong membrane with slightly movement allowed. The distal tibiofibular syndesmosis/inferior tibiofibular joint is a syndesmotic joint.
Where is the syndesmosis?
The syndesmosis is a fibrous joint held together by ligaments. It’s located near the ankle joint, between the tibia, or shinbone, and the distal fibula, or outside leg bone.
What is the interosseous membrane of the leg?
The interosseous membrane of the leg (middle tibiofibular ligament) extends between the interosseous crests of the tibia and fibula, helps stabilize the Tib-Fib relationship and separates the muscles on the front from those on the back of the leg.
What are the 3 ligaments in your ankle?
The ligaments around the ankle can be divided, depending on their anatomic position, into three groups: the lateral ligaments, the deltoid ligament on the medial side, and the ligaments of the tibiofibular syndesmosis that join the distal epiphyses of the bones of the leg (tibia and fibula).
What is the purpose of the distal tibiofibular syndesmosis?
Structure and Function [2] The primary function of the distal ligaments of the tibiofibular syndesmosis is to prevent the fibula from displacing (laterally, and/or anteriorly/posteriorly) from its groove in the tibia.
