Where did polar bears live before the Arctic Ocean became frozen over every winter?

This actually comprises several questions: 1/ Does the survival of polar bears depend on the Arctic Ocean being frozen over every winter?; if "yes": 2/ For how long has the Arctic Ocean been regularly frozen over every year? and 3/ Were there any polar bears before this time and, if so, where and how did they live?

Do hibernating bears get the equivalent of bed sores, and If not, why not?
