https://youtu.be/Hm1A-wTSn-w1️⃣ Prevalence of DTFS InjuriesInjuries to the distal tibiofibular syndesmosis (DTFS) are more frequent than previously believed.Previously estimated to represent 1%–18% of ligamentous ankle injuries, recent studies report an incidence of 17%–74% among sports-related ankle injuries.Syndesmotic injuries account for 18% of all lateral ankle sprains, with latent injuries..

https://youtu.be/dTVpd34T-HE ✔️Salter-Harris Type I Fracture of the Distal Phalanx Salter-Harris Type I fractures involve a fracture through the growth plate (physis) without bone involvement, often challenging to detect on radiographs. MRI is valuable for assessing physeal injuries, especially when radiographs are inconclusive. ✔️Key CharacteristicsFracture Location: The fracture occurs through..

https://youtu.be/9CmbPqSLxZE 1. Diagnostic Criteria for Morton NeuromaTo diagnose Morton neuroma, consider the following three MR imaging criteria:The lesion is centered in the neurovascular bundle on the plantar aspect of the intermetatarsal space.The lesion is well-demarcated.Its signal intensity is similar to skeletal muscle on T1-weighted images and less than fat on T2-weighted images. 2. Co..

https://youtu.be/Adfe07WqbFkATFL Avulsion FracturesThe most common type of ATFL injury is a pure ligamentous rupture, followed by an avulsion fracture from the tip of the lateral malleolus.Avulsion fractures from the talus are rare after lateral ankle sprains.Difficulty in Differentiating Os Subfibulare and Fibular Avulsion FracturesOs subfibulare and ATFL fibular avulsion fractures, especially ..

https://youtu.be/3VF_piDgBqcUnderstanding Anterior Talofibular Ligament (ATFL) InjuriesThe Anterior Talofibular Ligament (ATFL) is one of the most commonly injured ligaments in the ankle. This post highlights the types of ATFL injuries and key imaging features for diagnosis.Types of ATFL InjuriesPure Ligamentous RuptureAvulsion Fracture at the Fibular AttachmentAvulsion Fracture at the Talar Att..

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..

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. High Ankle Sprains and AITFLLigament Involved: Anterior inferior tibiofibular ligament (AITFL).Imagi..

https://youtu.be/d0PGAS9ZWd4 ✅Anterior Talofibular Ligament (ATFL)Location: Part of the lateral ankle ligament complex, stabilizing the talus.Anatomy: A flat, intracapsular ligament (6-10 mm long, 2 mm thick) connecting the lateral malleolus to the talar neck.Variants: Typically two bands, but may have one or three.MRI Features: ✅Posterior Talofibular Ligament (PTFL)Location: Part of the lateral..
