Aren't there materials out there that can change from "fluid" to "solid" based on electrical signals? Or maybe something like Oobleck instead. Then you could have some sort of spine-protector, that outlines/protects your back and is flexible by default, but if it can tell you're falling through the air somehow/rotating around, it starts being inflexible to protect the structure of your back.

I dunno, just brainstorming and have no experience building protective wear/devices.

That actually exists already!

The brand name of the material is D3o, it's used in products like the Fox Baseframe.

From personal experience this helps quite a bit, but i never had a crash where my spine took a hit.

Issue is, many people don't wear torso protection, just like a lot of people ride motorbikes in a T-Shirt/

I'm not a doctor, but I think most spinal injuries are caused by impact or compression from the axis of the spine (from one vertebrae to another). Not puncture injuries perpendicular to the torso.

Yeah, that makes sense. I was thinking something that when expanded, would protect the bottom somehow + the top (maybe helmet is connected to this imaginary "spine protector"), so compressions would be really difficult on that axis.
