Legendary Hall of Fame quarterback John Elway was diagnosed with Dupuytren's contracture, a progressive medical condition that affects the connective tissue beneath the palm of the hand. Commonly known as Viking disease, the condition causes thick nodules and cords to form, eventually pulling one or more fingers—most frequently the ring and pinky fingers—into a permanent bent position. Elway publicly shared that the affliction severely constricted his fingers and made holding items difficult before he ultimately pursued non-surgical treatments to successfully restore normal function.
