https://youtu.be/he2-XqAyvaA * The popliteomeniscal fascicles arise from the periphery of the posterior horn of the lateral meniscus and form a posterolateral meniscocapsular extension, which creates the popliteus hiatus. * The fascicles not only form the hiatus, which allows the popliteus tendon an avenue to course intra-articularly and maintain the integrity of the joint but stabilize and cont..

The dorsal part of the scapholu..

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 commonly used Mayo classification divides carpal instability into four major categories. 1. Carpal instability dissociative (CID), where there is dissociation of the bones in a single carpal row. The proximal carpal row is most commonly affected (i.e., SL instability; lunotriquetral instability). Distal carpal row dissociation is rare. 2. Carpal instability nondissociative includes instabili..

Articular-surface partial-thickness tear with intratendinous horizontal splitting tear of the infraspinatus tendon Intact supraspinatus tendon The footprint of the supraspinatus on the greater tuberosity is much smaller than previously believed, and this area of the greater tuberosity is actually occupied by a substantial amount of the infraspinatus. The anterior part of the infraspinatus partia..

Relatively small, triangular, the anteromedial footprint of the supraspinatus tendon at the superior facet and a comparatively large, trapezoidal footprint of the infraspinatus tendon occupying the anterolateral portion of the superior facet and the entire middle facet. The footprint of the supraspinatus had a triangular shape, which tapered away from the joint capsule. The footprint of the infr..

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..

With popliteus tears, it is important to note - the site of the tear (intra- articular or extra-articular), - the extent of tear (partial or full-thickness), - the presence of a bone fragment if there has been tendon avulsion - degree of tendon retraction Partial-thickness tear of the popliteus tendon, High-grade partial tearing of the PT at its femoral insertion Most popliteus tears are extra-a..
