If you mean your spine bend then its never as this surgery fuses the spine into one solid bone rather than the several vertebra's a spine is made up of,once we have been fused then there is no flexibility afterwards plus we have the rods to deal with too,
but if you mean lean forward then it varies,i still cannot lean over or bend after over 20 years ago but manage despite that,will add a link for scoliosis support so you can ask/answer questions or simply chat to those who also have it they will have answers on this and will most likely say they too cannot bend any more,

I have had the surgery and my back is so stiff now,but you soon adjust,hope this helps.
