In reply to still trying:
Commiserations, I hope you make a full recovery.
I fractured L1 and T12 and ruptured the interspinous ligament a number of years ago. It was an unstable fracture but did not need pinning or rods. The consultant I visited advised me to avoid any impacts for a year as well.
He explained the healing process has several stages. First the fractured bones would start to knit together with a soft substance after about 4 weeks (I did notice a drop in pain about this point). After that there would be ossification which would heal the fracture but leave the vertebrae bulky and slightly fragile (After about three months I had a definite bump on my spine). Finally the bulky bone in the facture is gradually replaced so would not be back to full strength for a year.
For a year I avoided anything which would or could cause an impact such as running or lead climbing.
After three months I started physio so reasoned that non-impact exercise was OK. I choose to interpret seconding and top roping as non-impact....
