My specialist wanted me to have an ALIF. I weighed up the pros and cons and decided against it. I figured it would be super difficult to undo anything that went wrong. I have since discovered Pilates. Swear by Pilates.
Mine did use screws (anterior and posterior, double the scars, double the fun!), so not the same, but mine did use illiac harvested bone and while it was painful when I woke up, it wasn't lingering or horrific.
