Disc Prosthesis in Neck Hernia Surgery

Disc prostheses are artificial prostheses used in neck hernia surgery in order to maintain the current disc height and provide movement in this segment, after the cervical disc, which causes complaints and presses on the nerve, is removed in patients diagnosed with neck hernia,

Although the disc prosthesis varies according to the producing company; The area of ​​this implant that comes into contact with the bones of the spine, that is, the surface that comes into contact with the endplates, contains cobalt chromium and polyethylene. In the middle and bottom of the prosthesis, a round convex surface articulates with an upper convex surface and overlaps each other. In addition, titanium sprinkled on the surface increases the sliding resistance on the bone surface, while increasing the contact with the bone surface. And it accelerates ossification, that is, fusion, in this region.

The ball-and-socket designed implant allows potential disc-like movements between the cervical spine. It resists bending forces. The disc prosthesis easily allows 20 degrees anterior-back and 20-degree lateral bending motion. Front back length 12-18 mm., side length 15-19 mm., height 5.6.7 mm. It's in size. It is MR compatible but creates artifacts in images like other metal prostheses.
