I think mentioning and discussing accidents is a good thing if it raises awareness for it happening and provides any useful tips or ideas.
I think the problem could be avoided or if the accidents occur the effect could be minimalized.
Firstly proper preparation of the rider, strengthening of certain muscles along the back especially in the lower back to prevent long term damage to the nerves, vertebrae or discs, it would also limit any damage being done. A lot of riders have lower back problems or injuries, some sudden, some long term like sciatica and similar nerve damage that could be avoided.
Secondly warming up properly with stretching and other suitable exercises to ensure that muscles and connective tissues are as flexible and also ready for the activity as possible, to reduce the likely hood of tearing and other damage.
Thirdly the right kind of armour for the situation, if your doing DH or freeride the full armour regardless if it's your last run or you've had a few beers. Shinnes, glasses for flies what ever the situation requires.
Fourthly proper maintenance of the bike and spot checks before you go for the days ride.
Fifthly having some common sense and truthfulness about your level of skill and talent and just how competent a rider you are in general.
All comes down to awareness and being bothered to do it though.
