Motion Sparing Artificial Disc

Motion Sparing Artificial Disc

Lumbar Disk Replacement (also called Total Disc Arthroplasty TDA) is the removal and replacement of one or several impaired discs in the lower back with an FDA approved motion sparing artificial disc (ActivL). The top and bottom of the disk are metallic plates that attach to either vertebrae. A curved, compressible plastic layer separates the metallic plates and replicates the nucleus of the spines natural discs, allowing them to slide and compress.
