I understand it is difficult to decide when each specialist you see tells you something different. But I would once again caution against taking advice off pprune for several reasons:
1. there is no way to determine if the person posting information actually knows what they are talking about
2. most spinal surgeons I know are fairly cautious people - I can't see any of them posting anonymous advice on how to manage a person they have never met
3. most spinal surgeons are fairly arrogant people - they all think their opinion is the best
I see from your post that you are in Spain. I imagine that is where you are being treated. Whilst I appreciate the standard of orthopaedic care might vary, my experience in the NHS of tourists returning from Spain (particularly Gran Canaria and Lanzarote) with fractures which have been mismanaged to various degrees would make me hesitant to seek treatment there. If you want a proper opinion, I would recommend making an outpatient clinic appt with a spinal surgeon at Royal National Orthopaedic Hospital Stanmore in London. It might cost you a bit if you aren't a UK resident, but it might save you life long grief if someone ***** your back up or even paralyses you.
