Elbow Ligaments The two main ligaments around the elbow are the ulnar collateral ligament (UCL) and the radial collateral ligament. Posterior view of the ligaments of the right shoulder joint; Posterior, lateral and medial views of the elbow showing skeletal anatomy in flexed and extended positions; Anterior views of the muscles of the right elbow. The three bony structures include the distal humerus, proximal radius, and proximal ulna. Ulnar Artery: The ulnar artery travels next to the ulnar nerve through Guyon’s canal in the wrist. Together these ligaments provide the main source of stability for the elbow, holding the humerus and the ulna tightly together. This Chapter reviews the MRI anatomy of ligamentous stabilizers of the elbow, diagnostic imaging considerations for ligament injuries, and resultant directional instability patterns concentrating on those most commonly encountered in clinical practice, valgus and posterolateral rotatory instability as well as elbow dislocation. The bony anatomy of the elbow joint requires a brief description to lay the framework for the collateral ligaments of the elbow. This Chapter reviews the MRI anatomy of ligamentous stabilizers of the elbow, diagnostic imaging considerations for ligament injuries, and resultant directional instability patterns concentrating on those most commonly encountered in clinical practice, valgus and posterolateral rotatory instability as well as elbow dislocation. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock. Capsule is a secondary stabilizer. The three bones that are responsible for the formation of the elbow joint are humerus, radius and ulna.It includes two articulations: (a) humero-ulnar articulation, between the trochlea of the humerus and trochlear notch of the ulna, and (b) humero-radial articulation, between the capitulum of the humerus and the head of radius. This bony prominence located just above the elbow on the outside is where the forearm muscles that straighten the fingers and wrist come together in one tendon to attach to the humerus. 3 Major Ligaments of the Elbow. Ligaments are a group of firm tissues that connect bones to other bones. Humero-radial articulation is between the capitulum of humerus and superior surface of head of radius.
