Elbow injuries can really throw a curveball to baseball pitchers. That's especially true if the injury's a torn or damaged ulnar collateral ligament (UCL), which usually results in surgery.
But pitchers aren't the only ones who are susceptible. UCL injuries also affect golfers, tennis players, quarterbacks and anyone who plays a sport that involves overhead motions (such as volleyball) or a risk of landing on an outstretched arm (such as hockey).
