About this study

Official title: Clinical Outcomes Following Posterior Lateral Fusion With the Dynesys(R) Spinal System

The primary purpose of this study is to track and document the clinical outcomes of patients with radicular pathology following posterior lateral fusion with the Dynesys Spinal System. Secondary purpose of this study is to assess outcomes with historical controls along a continuum of motion and anatomy sparing procedures.

Read the detailed description

This study will help the patient to the extent that it will allow the comparison of this unique treatment to the corpus of literature on radicular pathology, thus focusing a specific treatment for a specific pathology.

Keywords
dynamic stabilization, Dynesys, fusion success, Immobilization of spinal segments as an adjunct to fusion in the treatment of the following:, acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine, degenerative spondylolisthesis with objective evidence of neurologic impairment, failed previous fusion (pseudarthrosis).
Medical subject headings

Questions about this trial

What is this clinical trial studying?

An observational study of Spondylolisthesis, run by Zimmer Biomet at 1 site in United States.

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 6 inclusion and 16 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: finished, as of the sponsor's last update on 29 Sep 2011. 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 United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical Outcomes (time frame: Pre-op, Surgery, 3 month, 6 month, 12 months and 24 months). 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 29 Sep 2011.
