The recovery time after back fusion surgery
is determined by the extensiveness of the procedure, open or minimally invasive, and the number of levels fused.
The technique used also varies with screws, rods, cages, bone graft, or clamps. Generally if your work is heavy being off 2-3 months is common for extensive surgery. Light workers can return in 4-6 weeks. The fusion becomes solid in 6-12 month.
