Spine and Spinal Disorders

Spinal Arthroplasty and Motion Preservation

The fundamental objective of motion preservation surgery for the spine is to keep normal or almost normal motion in an effort to avoid the negative effects frequently associated with traditional spinal fusion, most notably the emergence of adjacent-level degenerative disc degeneration. Motion preservation surgery aims to closely resemble normal spinal biomechanics; as a result, issues related to conventional fusion should be reduced. Similar to how hip and knee arthroplasty is justified, so is motion preservation.
