Motion Sparing Neck Surgeries are increasingly recognized for their pivotal role in achieving more durable long-term outcomes for patients compared to traditional spinal fusion. Unlike fusion, which eliminates movement at the treated segment, innovative procedures such as artificial disc replacement (ADR) or dynamic stabilization techniques aim to preserve the natural biomechanics and range of motion of the cervical spine. This preservation significantly reduces the compensatory stress placed on adjacent vertebral levels, thereby mitigating the risk of adjacent segment disease (ASD)—a common long-term complication of fusion that often necessitates further surgery.
