bonjour. As above, I thought there may be degloving due impact or abrasive trauma within the cabin. Excessive compression followed by displacement (rapid) of soft tissue can cause it to slough off its supporting structure(s), mainly bone(s). If one was to smack something with one's arm at 200 knots, or 150, etc. likely the tissue would rupture and expose the skeletal structure beneath. This can happen merely due to g forces, without contact with a foreign object. At some acceleration, soft tissue will leave its substrate. We are entertaining 200g here, I think, more than sufficient.
merci.

I could direct you to MedLine or other, but allow me to retract my reference to degloving. It is likely a dead end, and probs just a distraction.
cheers.
