Comparison of Cage Versus Plate in One Level Cervical Disc Disease

2014-08-27 03:18:03 | BioPortfolio


There are largely 2 surgical methods for one-level cervical disc disease; cage only and plate/graft. Even there are many reports about the efficacy of either cage only or plate/graft, prospective comparative study is few. The object of the present study is to present design of prospective study and to demonstrate preliminary result.


Prospective study was started from April 2004 after permission by our Institutional Review Board. Inclusion criteria were single cervical disc disease with radiculopathy/myelopathy. We excluded patients with severe spondylosis, multiple disc disease, overt instability, osteoporosis or previous cervical operation history. Operation method was randomized using the table of random sampling numbers. All operations were performed with standard anterior-medial approach. Two types of cages and 2 types of plates were used: cage, MC+ cage (LDR, Austin, Tx, USA) or Solis cage (Stryker, Kalamazoo, Michigan, USA); plate, Black stone (Orthofix, McKinney, Tx, USA) or Atlantis (Medtronic, Minneapolis, MN, USA). We checked neck disability index (NDI), neck visual analogue scale (VAS) and limb VAS before operation and 1/3/6/12/24/36 months after operation. Disc height ratio, cervical lordosis and segmental lordosis at the index level were measured from X-rays and follow-up X-rays were obtained at before operation and 1/3/6/12/24/36 months after operation. The present prospective study was planned until 80 patients (cage n = 40, plate/graft n = 40) were enrolled.

Medical and Biotech [MESH] Definitions

The replacement of intervertebral discs in the spinal column with artificial devices. The procedure is done in the lumbar or cervical spine to relieve severe pain resulting from INTERVERTEBRAL DISC DEGENERATION.

The dissolving of the NUCLEUS PULPOSUS, the semi-gelatinous tissue of a displaced INTERVERTEBRAL DISC. It is usually achieved by the direct injection of a proteolytic enzyme, especially CHYMOPAPAIN, into the herniated disc.

Fibrocartilage inner core of the intervertebral disc. Prolapsed or bulged nucleus pulposus leads to INTERVERTEBRAL DISC DISPLACEMENT while proliferation of cells in the nucleus pulposus is associated with INTERVERTEBRAL DISC DEGENERATION.

Degenerative changes in the INTERVERTEBRAL DISC due to aging or structural damage, especially to the vertebral end-plates.

An INTERVERTEBRAL DISC in which the NUCLEUS PULPOSUS has protruded through surrounding ANNULUS FIBROSUS. This occurs most frequently in the lower lumbar region.
