Eksperimentel: Two level Prodisc-C vivo
Two level Prodisc-C vivo cervical artificial disc replacement.
|
Two level of Prodisc-C vivo artificial disc replacement will be done in one group of patients.
|
|
Aktiv komparator: Hybrid
This group of patients will be treated with hybrid construct, i.e., one level of Prodisc-C vivo and one level of anterior cervical discectomy fusion (ACDF).
|
The hybrid method will be used in one group of patients.

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).

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).
