About this study

Official title: Full-Endoscopic vs Open Discectomy for the Treatment of Symptomatic Lumbar Herniated Disc: A Prospective Multi-Center Randomized Study

The purpose of this study is to compare the clinical and radiographic outcomes of full endoscopic lumbar discectomy versus open lumbar decompression for the treatment of lumbar herniated discs in which the patient's leg pain is greater than back pain.

Read the detailed description

The study will be performed utilizing a prospective multi-center randomized model. Approximately 7 centers will be included in the study as listed above. Patients will be informed of clinical trial and asked if they would like to participate. Patients are informed that participation is optional. Patients may withdraw from study any time prior to or after surgery. Patients will be randomized 2:1 ratio endoscopic:open surgery. Both the endoscopic and open surgical techniques are utilized in standard of care. If a subject requires an open surgery approach (based on the surgeons assessment at the time of surgery pre or post incision) after they are randomized to the endoscopic arm, they will be switched to the open arm and included in the open crossover arm of the study.

Study procedures will occur at the following time points; Pre-op, 6 wk, 3 mon, 6 mon, 1 yr and 2 yr follow-up.Subjects will complete questionnaires that assess pain level and location, functional capacity, work and health status, medication usage and duration of symptoms.

Being tested
Lumbar discectomy Open, Lumbar discectomy Endoscopic
Medical subject headings

Questions about this trial

What is this clinical trial studying?

A study testing Lumbar discectomy Open and Lumbar discectomy Endoscopic in people with Lumbar Disc Herniation, run by Yale University 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 5 inclusion and 21 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: stopped early, as of the sponsor's last update on 7 Aug 2018. 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 was stopped early (reason given: Investigator Moved Institutions). Results are not available in the source record.

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?

Leg pain as assessed by VAS score (time frame: 2 years). 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 7 Aug 2018.
