Learn about motion preservation in spine care, including artificial disc replacement and other advanced treatment options designed to maintain spinal movement while relieving pain.
Motion preservation is an advanced approach to spine care that relieves pain while maintaining the spine’s natural movement. Unlike spinal fusion, these procedures are designed to treat certain spine conditions without permanently eliminating motion at the affected level.
Healthy spinal discs allow the spine to bend, twist, and absorb everyday forces. When a disc becomes damaged, motion-preserving procedures may help:
Motion-preserving procedures are not appropriate for every patient. Your healthcare provider will evaluate your diagnosis, spinal stability, overall health, bone quality, and imaging results to determine whether this treatment option is right for you.
Maintaining movement at the treated spinal level may provide several important benefits for appropriately selected patients.
Motion-preserving procedures may help:
Research continues to evaluate the long-term outcomes of motion-preserving procedures compared with traditional spinal fusion.
Several surgical techniques may help preserve spinal motion depending on the patient’s diagnosis.
Artificial disc replacement replaces a damaged spinal disc with an implant designed to mimic the function of a healthy disc. By preserving movement at the treated level, artificial disc replacement may reduce the increased stress that fusion can place on nearby spinal segments. It is most commonly used for carefully selected patients with cervical or lumbar degenerative disc disease.
Advances in spine surgery continue to expand treatment options that maintain spinal mobility whenever appropriate. These procedures may incorporate minimally invasive approaches, advanced surgical planning, computer navigation, and robotic guidance to improve precision while protecting surrounding tissues.
Both motion preservation and spinal fusion are proven treatment options for selected spine conditions. The most appropriate treatment depends on the individual patient and the specific condition being treated.
Motion Preservation may:
Spinal Fusion may:
Your spine specialist can help determine which treatment offers the greatest potential benefit based on your individual needs.
Motion preservation continues to evolve through ongoing clinical research and technological innovation. The National Spine Health Foundation supports research and education that helps patients better understand emerging treatment options, including artificial disc replacement and other motion-preserving procedures. As research advances, these technologies may continue to expand treatment possibilities for appropriately selected patients.
Neither treatment is universally better. The best option depends on your diagnosis, symptoms, spinal anatomy, and treatment goals. Your spine specialist will recommend the approach that is most appropriate for your condition.
Yes. Artificial disc replacement is designed to maintain movement at the treated spinal level while relieving pain caused by certain types of degenerative disc disease.
No. Motion-preserving procedures are appropriate only for carefully selected patients. A thorough evaluation by a spine specialist is necessary to determine whether these treatments are suitable.
