Patients with lumbar stenosis and degenerative spondylolisthesis may benefit from dynamic stabilization and adequate decompression by using a posterior replacement device.
Lumbar stenosis and degenerative spondylolisthesis have been traditionally treated with fusion and decompression. However, Dom Coric, MD stated that fusion does not stop motion at the facets. This can cause increased stress at levels above and below the fuse and increase the risk of reoperation. Decompression may be used to maintain motion and stabilize the situation.
