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.
How do you measure tibiofibular clear space?
Measurement. The tibiofibular clear space can be measured on an AP or mortice view of the ankle 6. It is measured 1 cm above the tibial plafond. It is described as the horizontal distance between the deepest point of the fibular groove or posterior tibial tubercle and the medial edge of the distal fibula 1-3.
What is tibiofibular clear space?
The tibiofibular clear space (TFCS) is a radiographic measure and defined as the space between the groove of the distal tibial prominence and the medial margin of the distal fibula 1-3.
What is the space between the tibia and fibula?
Definition / Description The tissue is strengthened by several ligaments. However, if you sprain your ankle, it is possible that the tissue between the two bones breaks. This can lead to a tibiofibular diastasis or syndesmosis, which is a separation of the tibia and the fibula.
How do you measure tib fib overlap?
Measurement. This measurement can be made on AP or mortise projections 5. The horizontal distance between the lateral margin of the anterior tubercle and the medial contour of the fibula is measured parallel and about 1 cm above the distal tibial plafond in a normal anteroposterior view of the ankle 1-3.
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 tibiofibular 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 is diastasis of the syndesmosis?
Syndesmotic diastasis was defined as tibiofibular clear space (TFCS) more than 6.0 mm on the anteroposterior or mortise radiographs, tibiofibular overlap (TFOL) less than 6.0 mm on the anteroposterior radiograph or less than 1.0 mm on the mortise radiographs [22], or medial clear space (MCS) more than superior clear …
