MRI Ankle (Anatomy) - Video Lesson

Hey, everyone. Welcome to today's lesson on the MRI of the ankle. In this lesson, we will look at the bony structures of the joint, important ligaments and tendons, and anatomy on different planes of MRI imaging. Let's get started. The ankle is a synovial hinge joint, which mainly functions to create movement of dorsiflexion and plantar flexion. It also has the capability of rotation. The joint is formed by the tibia, fibula, and talus. Key landmarks include the medial malleolus of the tibia and lateral malleolus of the fibula. The joint is stabilized by various ligaments and surrounding muscles and tendons. Now, let's take a look at the anatomy on some MRI images starting with the sagittal plane. Starting on the lateral side, we can see the lateral malleolus of the fibula. The peroneus brevis muscle and tendon are visible. The tendon can be identified as the black structure curving around the malleol.
