What is a radial collateral ligament?

Radial collateral liga is a strip of fibrous connective tissue connecting the humerus bone at the upper part of the arm with the ulna bone in the forearm. The exceeding of humerous and humeroranory joints that connect the humerus with the bones of the ulna and radius is located only on the outer elbow on both arms. This ligament helps to protect the elbow articular capsule on its side of the capsule wall reinforcement. In addition, because of its connection to the ring ligament on the ulna bone, the radial collateral liga helps to stabilize the bones of the radius in the proximal Radioulnar joint. The lateral epicondyle is the farthest of the two rounded bony eminence at the humerus base and is easy to feel when the arm is bent, only on the outside of the elbow. From there, the liga descends alongside the elbow just above the radius on the outside of the forearm and then divided into two sections. The rear part is cut back towards Ulnu, bones on the patečková side of the forearm, where it is inserted just below the elbow along the side or inner edges of the bone. This forms a direct connection of mEzi Humerus and Ulna Bones hold them together and provide lateral elbow stability.

The front, on the other hand, runs directly down from the side epicondyle towards the radius on the inch of the forearm side. Here, where the radius encounters humerus, the anterior radial collateral ligament with the ulp ligament is connected. Anular ligament is a circular ligament protruding to the side outside the upper part of the ulna and surrounds the bone head with a radius beside it to form a proximal radioul joint. As a finger slipped into the ring, the radius could rotate either the direction inside the ring ligament. This is what connects the radius to the ulna and allows the forearms to turn back and forth.

Since the proximal Radioulnar joint is found immediately below the gliding humerous and humeroradial joints in the elbow, it must connect it to the elbow to hold the structure together. This is another role of radial collateral ligament. Because its frontThe part connects the humerus with the ring ligament, although not directly to the radius, helps to maintain the radius in place in the ligament circle, and therefore ensures that the elbow movements - flexion and extension - may occur in parallel with the forearm rotation.
