Ask Dr. Santos: What Is The “Gold Standard” In Spine Surgery?
Surgical procedures for disc degeneration are always evolving and advancing. Dr. Santos explains how a procedure comes to be considered the “gold standard” in spine surgery.
Spinal fusion is currently considered the “gold standard” among surgical procedures used to address advanced degenerative disc disease. Over the last few years, alternative options to fusion have become available. One example is disc replacement surgery, which involves replacing the diseased disc with an artificial disc, thereby avoiding a fusion. Spine surgeon Dr. Edward Santos explains how surgical procedures are evaluated and come to be considered “gold standard.”
“Before we can offer any surgical procedure,” explains Dr. Santos, “it must be studied in clinical trials, demonstrated effective, and use devices approved by the FDA.”
What is a gold standard?
In order for a surgical procedure to be not only approved, but also considered “gold standard,” scientific evidence gathered over time must show that it’s the most successful surgery delivering the best outcomes compared to surgical alternatives. Medicine continually evolves and new techniques are approved, so “gold standard” surgery may change as researchers gather data and evaluate outcomes of newer techniques. However, it can take at least 10 years to evaluate the long-term success of a new procedure and to identify any unforeseen risks. A new procedure replaces a former “gold standard” procedure only if and when there is enough data to demonstrate that the new procedure delivers better outcomes.
Current gold standard in spine surgery
“Today, the gold standard in spine surgery for degenerative disc conditions is still fusion,” says Dr. Santos. “When a disc degenerates, a fusion procedure removes the damaged disc and ‘fuses’ together the vertebrae immediately above and below the removed disc. This fusion locks the vertebrae together and provides pain relief, but the patient loses natural range of motion in the fused segment of the spine, which then places additional pressure above and below the fused segment.
Future gold standard in spine surgery?
“Artificial discs were developed to provide a new surgical option that preserves range of motion in the spine,” he continues. “Artificial disc replacement surgeries replace the damaged disc with an implantable device that is designed to be flexible. This development is important because it helps to retain motion in the damaged spine segment. Therefore, patients don’t lose flexibility after surgery.
“More importantly,” Dr. Santos emphasizes, “when you preserve motion with an artificial disc, there is less postoperative stress on the discs directly above and below the replaced disc. A fusion procedure locks the segment in. Outcome research has shown that fusions lead to increased stress above and below the fused segment. That stress can lead to abnormal stresses in the discs, which can then degenerate, leading to further surgery down the line.”
As artificial disc surgical outcomes have been followed, some studies show that the motion-preserving benefits of disc replacement lead to better outcomes compared to fusions. Further long-term studies may lead to disc replacement becoming the gold standard for treatment in cervical disc degeneration. “There is no one surgery that is right for all spine conditions or patients,” says Dr. Santos. “Our job is to discuss the options, risks, and benefits based on the patient’s unique condition, and identify the surgery that will be his or her best option.”
