The elbow joint connects three bones in the arm, the humerus (upper arm bone) and the radium and ulna (forearm bones). Within the joint, there are strong, fibrous connective tissue that attach bones to one another. They allow the elbow to move properly and provide strength and stability to the joint. When ligaments are stretched, strained, sprained or torn, it results in pain and instability in the joint.
Little Leaguer’s elbow results in damage to the inside of the elbow, including the medial collateral ligament, as well as the medial epicondyle and the medial epicondylar aphophysis. The medial epicondyle is the growth plate on the inside end of the elbow, and this often becomes inflamed in adolescents experiencing Little Leaguer’s elbow.
