Cervical Disc Arthroplasty
Cervical disc arthroplasty is a newer procedure that attempts to provide decompression in the same manner that anterior cervical discectomy does while replacing the interbody fusion implants/grafts and the anterior plate with a synthetic joint in order to maintain motion. The theory is that by maintaining mobility at that joint, the surrounding joints will be less likely to deteriorate in the future (referred to as adjacent level disease). While there are promising avenues with the use of this technique, so far it has only been extensively studied in limited settings. It is however, an excellent option in a specific subgroup of patients. For these select few, it can be a very good alternative to the standard discectomy and fusion.
The video demonstrates one implant. There are other devices that have FDA approval and the device that is best for a patient may be slightly different than the one in the video. All of these devices have the same essential core characteristics.
