Sorry I forget how you fractured but did you fracture from bending and twisting and also had you had falls where you did not fracture? I think this is a topic I have not seen fleshed out anywhere. There are of course the usual statements about the danger of falls but not so much of considering the activities of daily life where you bend, twist or strain.
I'm curious how many people might share your experience that "twisting and contorting" are as risky as falls.

It's not the same as fracturing of course but I've had low back / hip issues since my late teens. I have finally in the past few years managed to stop straining my back with a key factor being learning to avoid movements that trigger pain and discomfort and finding alternative ways of moving my body that do not. Most of how to do that comes from Stuart McGill a noted low back expert. This may not directly translate to avoiding fractures but there might be some correspondence. Of course you can gently experiment with what causes one's low back pain and I don't know how you could do that for potential fractures. Still, I'm hoping the heightened awareness I've gained in avoiding pain triggers for low back pain might help me to some degree avoid movements that would result in a fracture. BTW some of the movements that I've learned to avoid are hip rotation exercises often recommended for low back pain.
I have not fractured. I quit playing pickleball once my DXA got in the mid -3's. I'm -4.1 now. My doc advised me to keep playing but play in a moderate manner. I told him I did not play sports in a moderate manner and was quitting. I exercise daily. Exercise I can do in a vigorous but controlled manner without sudden unexpected movements that you have in many sports. It's not as fun of course but I do enjoy it. I also play Beat Saber which is incredibly fun, great exercise and is safe for me.

windyshores,
Agreed. My doctor calls it the “BLT” - bend, lift, twist.
I am forced to bend snd lift my 17 year old dachshund several times a day. The PT taught me how to do it safely. So far, so good.
My mother had a compression fracture which
hugely degraded the last ten years of her life. Trying to avoid that.

Bending over lifting excessive weight (60 pounds) is what caused my fractures. I have fallen and not fractured. Obviously, trying not to.
