Discover the Advantages of Disc Replacements vs. Fusions

With a population of 324 million in the United States, it is estimated that approximately 17,500 new spinal cord injury cases occur each year, with an annual incidence rate of 54 points per one million people. 

If you or someone you know is experiencing chronic back or neck pain and have exhausted all treatment options without finding relief, you may be considering surgical interventions. While disc replacements and fusions are the two most common procedures for spinal issues, understanding their differences and long-term benefits is essential. Both surgeries aim to alleviate pain and improve mobility, but their approaches and expected outcomes vary. 

In this blog, we will explore the advantages of disc replacements vs. fusions and how opting for a minimally invasive spine surgery may provide even more benefits for your overall health and well-being. Keep reading to discover how these procedures can offer a new lease on life for those struggling with debilitating spinal conditions.

What is Disc Replacement?

Disc replacement, also known as artificial disc replacement, is a surgical procedure that involves removing the damaged intervertebral disc and replacing it with an artificial one. The process is usually recommended for patients with severe degenerative disc disease, in which the discs between the vertebrae in the spine wear down over time.

During this surgery, the damaged disc is removed and replaced with a prosthetic disc made of metal and plastic. The prosthetic disc is designed to mimic the natural movement of a healthy disc, allowing for better flexibility and reducing pain. One of the critical advantages of disc replacement is that it preserves the natural motion of the spine, unlike fusion, which limits movement.

What is Fusion?

Fusion, or spinal fusion, is a surgical procedure that involves permanently joining two or more vertebrae in the spine to create a solid, single bone. The process is usually recommended for patients with spinal instability, such as slipped or herniated discs, or those who have had a previous unsuccessful surgery.

The damaged disc or vertebrae are removed during the fusion surgery, and the remaining vertebrae are fused using bone grafts, screws, rods, or cages. Fusion surgery aims to stabilize the spine and prevent further movement of the damaged discs or vertebrae. However, this can also limit movement and flexibility in the affected area.

The differences between Disc Replacements and Fusions

While both procedures aim to relieve back pain, their approach and outcomes differ. Here are some critical differences between disc replacements and fusions:

One of the main differences between Disc Replacement and Fusion is the impact on spinal motion and mobility. With Disc Replacement, the artificial disc is designed to replicate the natural movement of a healthy disc, allowing for a more natural range of motion in the spine. In contrast, Fusion eliminates motion between the fused vertebrae, limiting flexibility in that area.

Due to the minimally invasive nature of Disc Replacement, patients typically have a shorter recovery time than Fusion. The fusion procedure requires metal screws and rods to stabilize the spine, which can cause more extended recovery periods and restrictions on movement. In contrast, patients undergoing Disc Replacement can return to their daily activities and work sooner, with some patients reporting feeling relief as early as two weeks post-surgery.

Another significant difference between Disc Replacement and Fusion is the preservation of adjacent discs. In a Fusion procedure, the fused area becomes more susceptible to wear and tear, which can lead to degeneration of the surrounding discs. In comparison, Disc Replacement only replaces the damaged disc, preserving the natural movement and function of the surrounding discs.

Reasons to choose Disc Replacements over Fusions

Here are the top reasons to choose disc replacement over fusions and why this minimally invasive procedure should be considered the preferred treatment for patients suffering from disc degeneration.

  1. Preserves spinal mobility

One of the main benefits of disc replacement is that it preserves spinal mobility. Unlike fusion, which involves fusing two vertebrae to eliminate motion between them, disc replacement maintains the natural movement and flexibility of the spine. This can significantly improve the patient’s quality of life and allow them to maintain an active lifestyle without restrictions.

  1. Reduced risk of adjacent segment disease

When a portion of the spine is immobilized with fusion, the discs adjacent to the fused area take on extra stress, which can lead to degeneration and the need for additional surgeries in the future. This condition is known as adjacent segment disease (ASD). Disc replacement prevents the adjacent discs from being affected, reducing the risk of developing ASD.

  1. No loss of height

Fusion involves removing the damaged disc and filling the gap with a spacer or bone graft, which can decrease spinal height. This loss of height affects the patient’s appearance, can lead to muscle imbalances, and cause long-term issues. In contrast, disc replacement preserves the size of the spine, ensuring proper alignment and reducing the risk of future complications.

  1. Faster recovery time

Disc replacement is a less invasive surgery compared to fusion. Instead of cutting through muscles and tissues to access the spine, the surgeon uses a smaller incision and moves the muscles aside, resulting in less trauma and damage. This minimally invasive approach leads to a faster recovery time, allowing patients to return to their daily activities sooner.

  1. Lower risk of complications

Fusion involves using hardware, such as screws and rods, to stabilize the spine. While this hardware is necessary for the fusion to be successful, it can also cause complications, such as nerve damage, infection, and hardware failure. Disc replacement does not require hardware, significantly reducing the risk of these complications.

  1. Treatment for multiple levels

Disc replacement can be performed on multiple spine levels, whereas fusion is usually limited to one or two groups. This is particularly beneficial for those with degenerative disc disease that affects numerous spine levels. Disc replacement offers a more comprehensive solution to alleviate back pain and improve spinal function by treating various levels.

With its many benefits, it’s no surprise that more and more patients are opting for Disc Replacement over Fusion. But, perhaps the most significant advantage of Disc Replacement is the minimally invasive approach. This means smaller incisions, less damage to surrounding tissues, and a faster recovery time. Not only does this result in less physical and emotional stress for the patient, but it also promotes a quicker return to their daily activities, including work.
