Artificial disc replacement surgery and fusion surgeries are two distinct approaches to spine surgery, each with its own set of advantages and considerations. These procedures cater to various spinal conditions, with ADR being particularly valuable in the case of lumbar total disc replacement.
Artificial disc replacement is employed to address issues such as damaged discs, pain caused by disc degeneration, and spinal stenosis. The procedure involves replacing the damaged disc with an artificial spinal disc.
These artificial discs are typically crafted from medical-grade plastic and, in some cases, titanium alloy. The primary aim of artificial disc replacement is to preserve disc space and maintain the spinal column's shock-absorbing properties, allowing for continued motion.
In contrast, fusion surgeries, as the name suggests, eliminate motion at the affected level of the spine. While fusion can alleviate pain and stabilize the spine, it also means that the fused segment loses its ability to move. Additionally, fusion may transfer stress to adjacent segments, potentially causing problems in the future.
The choice between artificial disc replacement and fusion depends on various factors, including the patient's specific condition, the surgical techniques employed, and the desired outcomes. Research and systematic reviews have supported the benefits of artificial disc replacement, such as motion preservation and improved clinical results. These findings make artificial disc replacement a viable option for many patients dealing with diseased discs and concerns related to disc height.
