About this study

Official title: Prospective Comparative Study of Open and Minimally Invasive Surgical Techniques in the Treatment of Degenerative One-level Stenosis of Lumbar Spine

The purpose of this study is to evaluate the clinical and radiological results of surgical treatment of one-level central stenosis of the lumbar spine using traditional open approach (PLIF) and a minimally invasive procedure (MIS TLIF). According to the hypothesis, we assume that unilateral approach of MIS TLIF allows for adequate bilateral decompression of one-level central stenosis of the lumbar spine. Using MIS TLIF it is possible to perform reliable fixation of a spine segment and the formation of a complete intervertebral bone fusion. The long-term clinical results of surgical treatment with minimally invasive technologies (MIS TLIF) and traditional open approach (PLIF) suspected to be comparable.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Oswestry Disability Index (ODI)

    Oswestry Disability Index - patient-reported physical and household activity. Minimum - 0 (the worst result, patient is not physically active). Maximum - 50 (the best result).

    Improvement of ODI post-operatively as compared to baseline

    Measured: Day of hospital discharge (10-15 day after surgery)

Secondary outcomes (6)
  1. Oswestry Disability Index (ODI)

    Oswestry Disability Index - patient-reported physical and household activity. Minimum - 0 (the worst result, patient is not physically active). Maximum - 50 (the best result).

    Improvement of ODI as compared to baseline

    Measured: 3, 6 and 12 months

  2. VAS (back, leg)

    Visual Analogue Scale (VAS) - patient-reported pain intensity (0 - no pain, 10 - unbearable pain).

    Improvement of VAS back- and leg pain intensity as compared to baseline

    Measured: Day of hospital discharge (10-15 day after surgery), 3, 6 and 12 months

  3. Surgery duration

    Surgery duration, in minutes

    Measured: Day of surgery

  4. Blood loss

    Blood loss, in milliliter

    Measured: Day of surgery

  5. MRI capacity spine canal

    Changes of spine canal capacity of spine segment, in sq. cm., as compared to baseline

    Measured: Day of hospital discharge (10-15 day after surgery)

  6. Bone fusion

    Intervertebral bone fusion formation, in degree (I, II, III or IV degree according to Tan)

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Decompression, PLIF and MIS TLIF in people with Spinal Stenosis Lumbar Canal With Neurogenic Claudication (Diagnosis), run by Novosibirsk Research Institute of Traumatology and Orthopaedics n.a. Ya.L. Tsivyan at 1 site in Russia.

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 3 inclusion and 6 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 14 May 2020. 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 Russia. 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: Recruitment terminated, all follow-up visits were canceled due to quarantine). 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) (time frame: Day of hospital discharge (10-15 day after surgery)). 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 14 May 2020.
