A 13 year-old right hand dominant male presented with posterior right shoulder pain and stiffness two days following a tubing accident. He believed his shoulder had been forced into hyperabduction and extension when he fell off the tube at high speeds. He denied subjective instability at the time of injury, but quickly developed posterior shoulder pain and stiffness. He rated his pain as 8/10, increased with overhead activity, and denied neurological symptoms.
