In most cases, a physician will diagnose an<unk>  collateral<unk>  injury using a patient’s medical history and a physical examination that includes a valgus stress test. The valgus stress test is performed on both arms and a positive test is indicated by pain on the affected arm that is not present on the uninvolved side. Physicians often utilize imaging techniques such as ultrasound, x-rays and magnetic resonance imaging or arthroscopic surgery to aid with making a proper diagnosis. Classification A slow and chronic deterioration of the<unk>  collateral<unk>  can be due to repetitive stress acting on the<unk>  At first, pain can be bearable and can worsen to an extent where it can terminate an athlete’s career. The repetitive stress placed on the<unk> causes micro tears in the<unk>  resulting in the loss of structural integrity over time. The acute rupture is less common compared to the slow deterioration injury. The acute rupture occurs in collisions when the elbow is in flexion such as that in a wrestling match or a tackle in football. The<unk>  collateral<unk>  distributes over fifty percent of the medial support of the elbow. This can result in an<unk>  collateral<unk>  injury or a dislocated elbow causing severe damage to the elbow and the radioulnar joints.
