went to the doctor for a checkup 5 weeks after the surgery. He said the xrays showed the hardware was solid. I asked him if he could see any bone growth yet, and he claimed it will probably be another 3 months before we see any. Does this sound right? I've heard of people being fused in 3 months, let alone just starting to see bone growth. It was a 2 level alif with hardware from the back L4-s1.
