Incidentally, her title references "social media" rather than Twitter, which I think is right; it's not hard to imagine, say, Facebook playing the same role. What's relevant is that she got word of her plight out to a network of people in a way that would be harder to do otherwise, and that feedback from this network led to a fundamentally different outcome than that experienced (I imagine) by most people with broken spines who are having unnecessary surgery and narcotics forced on them against their will.
