  • Adult aged 18 years or older
  • Male or Female subject that had previously received transsacral single-level procedure when used in conjunction with bilateral pedicle screw fixation or TLIF single-level procedure with bilateral supplemental screw fixation (e.g. pedicle screws, anterior devices with screw anchoring, anterior lumber plates) as an adjunct to fusion at L5-S1 to treat spinal stenosis, spondylolithesis or degenerative disc disease (DDD)

About this study

The purpose of this retrospective data review is to evaluate the health economic drivers and complications of two surgical procedures: transsacral lumbar interbody fusion and transforaminal lumbar interbody fusion when used in conjunction with bilateral supplemental screw fixation as an adjunct to fusion. Devices used in both systems are cleared for use and comply with US regulations and requirements.

Read the detailed description

Study Objective:

The study objective is to demonstrate via retrospective data review the relative value of two lumbar fusion procedures: transsacral lumbar interbody fusion and the transforaminal lumbar interbody fusion when used in conjunction with bilateral supplemental screw fixation as an adjunct to fusion. Subject candidates are those who had required fusion at L5-S1 where this was the only lumbar level treated for spinal stenosis, spondylolisthesis, or degenerative disc disease (DDD).

Consecutive subjects who were treated with the transsacral lumbar interbody fusion or transforaminal lumbar interbody fusion procedure at least 1 year (- 2 months) prior to the date the data is collected will be evaluated.

Study Design, Endpoints:

Primary Endpoint:

Safety: Incidence of reported adverse events, including those requiring medical intervention, by 3 months post-operative.

Secondary Endpoints:

Health Economic: Operative measures, including the direct and surrogate measurement of estimated blood loss, anesthesia time, transfusions, length of surgery and time to hospital discharge, as applicable.

Health Economic: Comparative hospital data (from time of admission through time of discharge)

Clinical Effectiveness: A decrease in back pain compared to baseline at 3 months (+/-2 weeks) as measured by Visual Analog Scale (VAS).

Clinical Effectiveness: A decrease in disability compared to baseline at 3 months (+/-2 weeks) as measured by the Oswestry Disability Index (ODI).

Study Design, Enrollment:

Approximately 200 subjects will be enrolled in this study, 100 subjects who have been treated with transsacral lumbar interbody fusion and 100 subjects who have been treated with transforaminal lumbar interbody fusion.

Study Design, Analyses:

The retrospective clinical evaluation will collect and compare results for the procedure transsacral lumbar interbody fusion versus transforaminal lumbar interbody fusion as defined by the primary and secondary endpoints.

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?

Safety (time frame: 3 months post-operative). 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 3 Sep 2014.
