Detaljeret beskrivelse

This is a prospective, randomized, multicenter trial at 7 years of follow-up comparing two level ProDisc-C vivo artificial cervical disc replacement and hybrid construct, i.e., combining ACDF (Anterior cervical discectomy fusion) and ProDisc-C vivo to treat degenerative disc disease (DDD). 542 DDD patients (age from 20 to 70) from several hospitals matching the inclusion criteria will be randomly assigned to two groups (271 patients in each group). One group will be treated with two level ProDisc-C vivo disc replacement. The other group will be treated with hybrid construct. Clinical outcomes and radiological analysis will be done at 1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments.

Intervention / Behandling
Eksperimentel: Two level Prodisc-C vivo
Two level Prodisc-C vivo cervical artificial disc replacement.
Procedure: Two level Prodisc-C vivo
Two level of Prodisc-C vivo artificial disc replacement will be done in one group of patients.
Aktiv komparator: Hybrid

Foranstaltningsbeskrivelse
Tidsramme
Change of overall success rate
Tidsramme: The overall success will be assessed at each time point (1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
A patient's outcome was considered an overall success if all of the following conditions were met:1) postoperative (Neck Disability Index) NDI score improvement of at least a 15-point increase from preoperative score; 2) maintenance or improvement in neurological status; 3) disc height success; 4) no serious adverse event classified as implant associated or implant/surgical procedure associated; and 5) no additional surgical procedure classified as a "failure".
The overall success will be assessed at each time point (1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).

Foranstaltningsbeskrivelse
Tidsramme
Change of sagittal angular motion
Tidsramme: The radiographs will be obtained at each study point (before surgery,1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
Neutral anteroposterior and lateral radiographs and dynamic flexion-extension lateral radiographs.
The radiographs will be obtained at each study point (before surgery,1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
Change of NDI Scores
Tidsramme: The NDI scores will be assessed at each study point (before surgery,1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
The neck disability index(NDI) questionnaire measures the level of pain and disability associated with various activities. The NDI is a 10-item, 50-point index that assesses different aspects of daily functioning in patients with neck pain. Each item is scored 0 to 5. The NDI score is a sum of the scores of the10-item. Clinical effects will be evaluated based on scores of the NDI. Higher values represent a better outcome.
The NDI scores will be assessed at each study point (before surgery,1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
Change of Arm and Neck pain
Tidsramme: Neck and arm pain scores will be measured at each study point (before surgery,1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
Neck and arm pain scores will be measured using a visual analogue scale (VAS) from "0' (no sensation) to '100"(the most intense pain imaginable) where 30 means "pain threshold".
Neck and arm pain scores will be measured at each study point (before surgery,1.5, 3, 6, 12, 24, 36, 60, and 84 months after the surgical treatments).
