As previously reported, Randy Orton suffered a dislocated shoulder at the WWE Tribute to the Troops tapings.
Orton suffers from a condition called hypermobile shoulders, which allows his shoulders to stretch back in a much greater range of motion than the average person. The downside to the condition is that he's more prone to dislocating his shoulders and his shoulder joints will wear down much faster than the average person. This could also lead to more health issues as he gets older.
