A study testing Anterior cervical discectomy with prosthetic disc replacement / ESP. and Anterior cervical discectomy with prosthetic disc replacement / Squale. in people with Intervertebral Disc Displacement, run by Technische Universität Dresden at 1 site in Germany.
Trial summary
This is an investigator-initiated study. The primary goal is to evaluate the efficacy of two different cervical disc devices (prosthesis vs rigid spacer) with respect to postoperative change in neck disability index.

Questions about this trial
What is this clinical trial studying?
A study testing Anterior cervical discectomy with prosthetic disc replacement / ESP. and Anterior cervical discectomy with prosthetic disc replacement / Squale. in people with Intervertebral Disc Displacement, run by Technische Universität Dresden at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 18 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Neck disability index compared to baseline (time frame: 6 weeks, 3, 6, 12 and 24 months postoperative). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Oct 2016.
