To conduct a clinical and radiological assessment of the follow-up of the patients undergoing cervical disc replacement with the PCMO (Cervitech).


Since December 2002 to January 2004, 111 cervical discs were implanted in 74 patients, 43 female and 31 male, with signs medular or radicular compression by cervical spine degenerative disease. Between these, 26 patients, 16 female and 10 male, were evaluated outcomes for one year follow- up. They were diagnosed by clinical examination, static and dynamic cervical X-ray and MRI. The follow-up comprised VAS, NDI and TIGT scales and ODOM criteria, preoperative and postoperative in the 1st, 3rd, 6th, 9th and 12th month, in addition to the appropriate X-ray monitoring.


The average age was 44 years ( 28 - 67). Thirteen patients were diagnosed with DDD (Degenerative Disc Disease); 9 with Nucleus Pulposus Hernia; 4 with Adjacent Segment Disease. Seventeen patients were treated with one prosthesis, 8 with two prostheses and 1 patient with three prostheses. Thirty-six discs were implanted: 2 x C3-C4; 6 x C4-C5; 18 x C5-C6; 10 x C6-C7. Preoperative evaluation: VAS: 8; NDI: 45; TIGT: 14. Postoperative evaluation: 1st month, VAS: 4, NDI: 23, TIGT: 7; and at 1 year: VAS: 2; NDI: 8; TIGT: 4. ODOM criteria: Excellent: 11, Good: 12, Fair: 3, Bad: 0 in the first month after the operation, and Excellent: 13, Good: 12, Fair: 1 and Bad: 0 at 1 year of follow-up. The X-ray assessment was conducted with static and dynamic X-rays, dynamic fluoroscopy, evidencing an average ROM of 15 degrees in flexion-extension in the patients throughout the follow-up.


Prosthetic cervical disc replacement with PCM (Cervitech) proved to be an excellent treatment option for degenerative disc disease, with excellent clinical and radiological results, improving the patients' quality of life.
