To say without question that the reason so many of the cyclists your group have had fractures is low bone density is fatally flawed. If you fall the wrong way, no matter your bone density, it will result in bones breaking.
You are right, this is serious business, but to rush through therapy and risk possible organ injury is not reasonable.
First do no harm = make sure therapy is safe. When in doubt, don't risk people's health, short term or long term.
