About this study

Official title: Oblique Lateral Interbody Fusion Versus Minimally Invasive Transforaminal Lumbar Interbody Fusion for Lumbar Spinal Stenosis

The investigators will retrospectively study lumbar spinal stenosis patients who underwent OLIF or MIS-TLIF with percutaneous pedicle screw fixation between January 2016 and December 2019.The investigators will measure estimated blood loss, operative time, hospital stay, cost, reoperation, and complication incidence, visual analogue scale (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA), and Short Form-36 (SF-36) scores, discal and foraminal height, lumbar lordotic angle, and fusion status.The investigators will conduct to evaluate postoperative improvements, complications, and reoperation rates between patients with lumbar spinal stenosis (LSS) undergoing oblique lateral interbody fusion (OLIF) or minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).

    Measured: 2 Years

Secondary outcomes (4)
  1. Japanese Orthopaedic Association (JOA)

  2. visual analogue scale (VAS)

    Before surgery and at the last follow-up, the following information was recorded

    Measured: 2 Years

  3. Short Form-36 (SF-36) scores

Questions about this trial

What is this clinical trial studying?

An observational study of Lumbar Spinal Stenosis, run by Tang-Du Hospital.

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 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 3 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Oswestry Disability Index (ODI), , and Short Form-36 (SF-36) scores; discal and foraminal height; lumbar lordotic angle; and fusion status. (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 3 Mar 2021.
