CALCANEOFIBULAR LIGAMENT (CFL) TEAR MRI
CALCANEOFIBULAR LIGAMENT (CFL) TEAR NORMAL MRI
- The Calcaneofibular ligament is a small lateral ankle ligament that is often torn.
- Its normal MRI appearance is a thin low signal structure (Pink arrows) that extends from the calcaneum to the fibula and passes deep to the peroneal tendons (Green arrows).
CALCANEOFIBULAR LIGAMENT (CFL) TEAR MRI ANKLE: WHAT TO LOOK FOR
The Calcaneofibular ligament is a small lateral ankle ligament that is often torn.
Here is what to look for when assessing for an acute tear of the Calcaneofibular ligament on MRI.
- Thickened, hyper-intense and ill defined calcaneofibular ligament (Pink arrows).
- This can involve the entire ligament or a portion of it.
- The anatomical landmark to find the CFL are the Peroneal tendons (Blue arrows) with the CFL lying deep to it between the peroneal tendons and calcaneum.

TEST YOURSELF ON SOME COMMON & FREQUENTLY ASKED QUESTIONS
WHAT IS THE NORMAL MRI APPEARANCE OF THE CALCANEOFIBULAR LIGAMENT:
The normal MRI appearance of the Calcaneofibular ligament is a thin low signal structure that extends from the calcaneum to the fibula and passes deep to the peroneal tendons.
HOW DOES AN ACUTE HIGH-GRADE TEAR OF THE CALCANEOFIBULAR LIGAMENT APPEAR ON AN MRI?
An acute high-grade tear of the Calcaneofibular ligament appears as thickening, hyper-intensity, and ill definition of the ligament.
WHAT ANATOMICAL LANDMARK CAN HELP LOCATE THE CALCANEOFIBULAR LIGAMENT ON AN MRI?
The Peroneal tendons on an MRI can serve as an anatomical landmark to locate the Calcaneofibular ligamentFrom International Journal of Physical Medicine & Rehabilitation.
HOW WOULD YOU DESCRIBE THE APPEARANCE OF A NORMAL CALCANEOFIBULAR LIGAMENT ON AN MRI?
A normal Calcaneofibular ligament appears as a thin low signal structure on an MRI.
