Hi AineMuirne, Welcome.

Keeping your spine healthy is usually a matter of genetics (which you can't do much about) and common sense (which you can).

Eat right (making sure you get enough calcium, etc. Google: strong bones), exercise (but don't overdo), don't smoke, drink only in moderation, don't abuse drugs, wear seatbelts & appropriate safety equipment, yadda, yadda, yadda...

There are never any sure things (guarantees) in life except death & taxes. However, I think there's a lot to be said for attitude/positive thinking. If you go through life believing you'll have further spine issues, you very well may. Especially if you subconsciously resign yourself to that fate, you may be likely to help it come to pass by not taking care of yourself.

OTOH, if you have good genetics (no family history of osteoporosis or other relevant medical conditions), take care of yourself, and believe things will turn out well, there's every chance things will go well and you'll be fine.
