Study groups in NCT02057744
Study groupRoleWhat they receive
Robotic-guidedAdult patients (21 years or older) undergoing short (4 or less consecutive vertebrae) thoracic, lumbar or lumbosacral percutaneous/minimally invasive robotic-guided spinal fixation surgery.
Freehand image-guidedAdult patients (21 years or older) undergoing short (4 or less consecutive vertebrae) thoracic, lumbar or lumbosacral percutaneous/minimally invasive image-guided freehand or navigated spinal fixation surgery.

What is being measured

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

  1. Intra-operative exposure to x-ray radiation

    Reading of exposure in seconds (and KvP if available) from C-arm or other imaging system used in the operating room.

    Measured: Day of surgery

  2. Surgical complications

    New neural deficits, implant-related durotomy, infection requiring return to surgery, hardware failure requiring removal, vertebral body fracture, failure to fuse

    Measured: Within first year from day of surgery

  3. Revision surgeries

    All cause revisions

    Measured: 1 year

Secondary outcomes (6)
  1. Pedicle screw instrumentation accuracy

    Accuracy will be quantified in millimeters and scored using the Gertzbein-Robbins classification, based on postoperative CTs that are clinically necessary for the management of the patient.

    Measured: Within 1 year of surgery, if indicated by surgeon and clinically necessary

  2. Incidence of pseudoarthrosis (malunion)

    Failure of the operated spinal segment to fuse.

    Measured: Within 1 year from surgery

  3. Length of convalescence

    Length of stay at the hospital, destination at discharge, time to return to normal activities, time to return to work

    Measured: Within 1 year of surgery

  4. Times of intra-operative stages

    instrumentation time per screw, total surgery time

    Measured: Day of surgery

  5. Ratio of executed vs. planned screws

    number of screws planned to be robotically inserted and manually inserted instead and cause.

    Measured: Day of surgery

  6. Quality of life assessment

    Health related quality of life questionnaires, including: back and leg Visual Analog Scale (VAS), Oswestry Disability Index (ODI), European Quality % Dimensions (EQ-5D-5L)

    Measured: Each visit up to 1 year1

Questions about this trial

What is this clinical trial studying?

An observational study of Degenerative Spine Disease and Spondylolisthesis, run by Mazor Robotics at 9 sites 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 14 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: status not confirmed, as of the sponsor's last update on 20 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites 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?

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?

Intra-operative exposure to x-ray radiation (time frame: Day of surgery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02057744, which also lists 3 linked publications.

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 20 Aug 2019.
