Cervical Spine; Movement Before and After Anterior Cervical Discectomy, With or Without a Cervical Disc Prosthesis

2014-07-24 14:13:55 | BioPortfolio

Summary

The purpose of this study is to find out if use of a cervical disc prosthesis in the treatment of a cervical disc herniation preserves or restores normal mobility and movement in the cervical spine.

Description

Intractable nerve pain to the arm caused by a cervical disc herniation is typically treated by removal of the protruding disc through an operation. Fusion of the discs follows in about 70% of cases.

Adjacent disc disease (ADD), symptomatic degenerative changes in the levels adjacent to the operated level is regarded as a late complication. Fusion at the operated level is thought to contribute to this process due to compensative increased mobility and stress on the adjacent segments.

Keeping the operated segment mobile through the use of a cervical disc prosthesis possibly prevents ADD.

We hypothesize that use of a cervical disc prosthesis preserves or restores normal mobility to the cervical spine. To test this hypothesis subjects are randomised in a group receiving a standard anterior cervical discectomy, and a group receiving a standard discectomy with placement of a cervical disc prosthesis. Digital X-ray cinematographic videos are made of a flexion/extension movement. The videos will be analyzed manually and through a newly designed automated program, to check for mobility and order of movement.

Medical and Biotech [MESH] Definitions

Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation. In addition to standard surgical removal, it can be performed by percutaneous diskectomy (DISKECTOMY, PERCUTANEOUS) or by laparoscopic diskectomy, the former being the more common.

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.

A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)

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.
