The elbow is a frequent site of injury to the throwing athlete. Baseball pitchers have the highest frequency index of these injuries. Andrews, Jobe, and Ponce have dedicated themselves to study and establish the mechanisms that produce these injuries and surgically treat injuries such as rupture of the medial collateral ligament of the elbow (Tommy John surgery), valgus stress syndrome, osteochondritis lesions of capitellum of the humerus and the posteromedial osteophytes of the elbow. Due to the mechanics involved in the throwing motion, these structures, both in the medial aspects and in the lateral areas of the elbow, are under tremendous tension. These injuries can occur as a result of acute trauma or can occur as a result of excessive use, repetitive use or repetitive compression of reiterative forces. The American Sports Medicine Institute (ASMI), the Andrews Sports Medicine and Orthopedic Center of Alabama (ASMOC) and the Latin American Sports Medicine Institute (LASMI) have devoted a significant amount of time to the care and investigation of UCL injuries in youth pitchers as well as professional baseball players. At AMC we are able to take care of the throwing elbow ulnar collateral ligament related injuries.
