https://www.instagram.com/msk_mri/ The calcaneocuboid joint is stabilized by the dorsal calcaneocuboid ligament, short and long plantar ligaments, and calcaneocuboid component of the bifurcate ligament. ​​The calcaneocuboid joint capsule is reinforced dorsolaterally by the dorsal calcaneocuboid ligament The long and short plantar ligaments (sometimes referred to together as the plantar or inferi..

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..

The flexor retinaculum is often torn in conjunction with a tear of the superficial deltoid ligament, or in association with ankle fracture. Tears of the flexor retinaculum have been described in association with tibialis posterior tendon dislocation. An isolated tear of the flexor retinaculum is rare. “Fascial sleeve of the medial malleolus,” is composed of the superficial deltoid origin, the me..

The spectrum of tears ranges from microtears to interstitial tears (parallel to the long axis of the Achilles), to partial tears, and eventually to complete tears (ruptures). Typically, in a young 'normal' individual, the Achilles tendon ruptures in the 'critical zone’, which is a region of relative watershed hypovascularity 2-6 cm proximal to insertion. The Achilles tendon tear classification i..

Jogger’s foot can develop at the Henry knot owing to repetitive trauma to the nerve, especially while running with increased heel valgus and foot pronation. Patients usually present with heel and arch pain, tenderness and a positive Tinel sign posterior to the navicular tuberosity, and numbness along the medial plantar foot. • MR: Edema or atrophy of the abductor hallucis and flexor digitorum br..
