I've had 2 Vertiflex implants put in my back. The first one was implanted in January 2020. In April I had an epidural or pain shot which did no good but I had sporadic relief, but not consistent relief. It got worse over the next few months so my doctor installed a second one in July. Now my back is much worse. I have to walk with a cane, and everytime I stand up I feel like I'm going to fall. My back feels like it is not stable. My doctor was disappointed with the post surgery xrays, and said he expected a much better result. Now it's about 4 months since the second surgery, and I'm nearly crippled. My back was much better before the surgeries than it is now. I wouldn't recommend this type of surgery for someone who has a really bad back as I do. My prior surgery where they did a decompressive lamenectomy and a discectomy worked great for about 8 years. This Vertiflex surgery has only made my situation much worse. I wouldn't do it again.
