Nick Vastolla is a senior on his lacrosse team.  He is running down the field, with the ball in the net of his lacrosse stick, when he passes the ball to another player and is struck by the opponent’s lacrosse stick on the right forearm.  Mr. Vastolla hears a pop and feels immediate pain.  He is assisted off the field and is evaluated on the sidelines.  He has edema, localized point tenderness, and ecchymosis where the stick struck his right forearm.  The localized point tenderness is along the upper third of the ulna.  Mr. Vastolla has no deformity, but percussion and compression/squeeze test results are positive.  He is immobilized and referred for radiography, the results of which indicate an ulna fracture.  A cast that extends over the wrist and forearm is made for his arm.
