Hi,
I'm also in S. Florida (Boca Raton) and about 2 weeks post-fusion of L4/L5, L5/S1 with hardware. Also had repair of sciatic nerve. So far surgery has gone much better than I expected, although the nerve pain was terrible the first week.
I see Dr. Barth Green in Miami, who is about the best you can see down here, but probably not who you would see if your DH's case is simple and straightforward because it is very difficult to get in to see him. But if his case is at all complicated I would recommend going through the hassle.
I do know two other people who have had more straightforward back surgeries down here, one with a doctor in Wellington and another with a doctor in Fort Lauderdale. I don't remeraber the doctors names off the top of my head, but could probably get them if you are still interested. Both seemed to be pretty happy with the outcome of their surgeries.
