It’s important to understand that people—not even Homo sapiens!—living at what must have been the subsistence margin, without states or written language or metal tools or electricity or antibiotics, managed to keep this person alive. They devoted resources to his care and survival. He lived for years, possibly decades, with a severe disability at a time when his community would have been doing things like fighting off literal cave bears.
Our society has inconceivably more material, social, and technological resources to bring to bear to help each other. We have no excuse.
