Fusion Versus ADR surgery
Convention Spinal surgery usually involves fusion type surgery or artificial disc surgery (ADR). Other types of conventional spine surgery such as laminotomy will not be discussed here and we will focus more on the stability type surgery. Fusion spine surgery involves permanently fixating the spine to avoid any motion at the level of the fusion. This can be done with cages, rods and screws, or bone alone. The bones (vertebral bodies) are pulled slightly apart and then the fixation system is used to keep the bones permanently at the point. In contrast ADR surgery involves the insertion of a metallic device which pulls the same bone apart as expressed above but also allows some degree of motion to be present in the area of the ADR. This motion is thought to help eliminate or at least decrease the problem of disc degeneration that occurs with regular fusions. The discs degenerate due to the fixation causing increased motion above and below the fusion and this "wears out" those discs. ADR's have been around for around 10 years or so and success rates are similar to fusion surgery or minimally invasive surgery. This success rate is around 70% good to excellent and thus 30% of patients either get little to no improvement or actually get worse. Minimally invasive type surgery such as microspinoscopy or endoscopic laser spine surgery offer similar success rates but with fewer patients claiming bad results or negative outcomes. We hope this has helped to educate you on spine surgery.
