[Essential] Comprehensive Guide to Calcaneofibular Ligament (CFL) Anatomy on MRI

https://youtu.be/wiHOwkRSeS8✅ The calcaneofibular ligament (CFL) is the second most commonly injured ligament in lateral ankle sprains, following the anterior talofibular ligament (ATFL). Understanding its anatomy and imaging characteristics is critical for accurate diagnosis. Orientation: It follows a curved course, requiring evaluation in multiple imaging planes.Dimensions: Rounded in cross-se..

[Essential] Comparison Between ATFL and AITFL: Key Insights for Ankle Injury Diagnosis

https://youtu.be/ZMlA5DH3Kz41. Lateral Ankle Sprains and ATFLLigament Involved: Anterior talofibular ligament (ATFL).Imaging Characteristics: Best seen on axial MRI at the level where the talus appears elongated.Associated Injury: Often occurs in lateral ankle sprains due to inversion injuries.2.

The anterior talofibular ligament (ATFL) is composed of the superior (S-ATFL) and inferior fascicle (I-ATFL). Both fascicles have a contiguous footprint on the anterior distal fibula border, however, their distal insertion on the talus is located apart from each other. The superior fascicle of the ATFL is a distinct anatomical structure, whereas the inferior ATFL fascicle and the CFL share some ..

The lateral ligament complex of the ankle consists of the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament. This ligament plays an important role in limiting anterior displacement, internal rotation of the talus, and plantar flexion of the ankle The anterior talofibular ligament extends from the anterolateral malleolar tip to the talar neck..

When instability persists despite an anatomic repair, many surgeons turn to anatomic lateral ankle ligament reconstruction with autogenous or allogenic tendons. Several techniques have been described and most require the creation of two transosseous tunnels in the distal fibula, one for the ATFL and one for the CFL. The popularity of these procedures has been increasing over the last decade with..

ATFL The ATFL is best imaged on axial T1 or high-resolution PD MR images, appearing as a flat, thin, homogeneous band of low signal intensity arising from the anterior margin of the lateral malleolus and coursing anteromedially downward to attach onto the neck of the talus, just anterior to the fibular articular cartilage. The CFL is large, strong, and cordlike. It arises from the deep aspect of..
