MRI Elbow (Anatomy & Pathology) - Video Lesson

Hey, everyone. Welcome to today's lesson on the MRI of the elbow joint. 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 elbow joint is classified as a hinge joint, allowing primarily flexion and extension movement. It is comprised of the humerus, radius, and ulna. On the humerus, the trochlea articulates with the ulna, while the capitulum interfaces with the radius. The olecranon fossa located posteriorly on the humerus accommodates the ulna's olecranon process during extension. The radius features the radial head, which articulates with the capitulum and allows for rotational movement. The ulna's olecranon and coronoid processes are key landmarks with the trochlear notch forming the primary articulation with the humerus. While bony structures are important in MRI imaging, soft tissues are often the focus of muscular
