Trial summary

This study is designed to evaluate the clinical utility of a known intraoperative neuromonitoring modality (SSEP) using saphenous nerve as the site of stimulation to identify changes to the lumbar nerves which may be at risk during the lateral lumbar interbody fusion (LLIF) procedure.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients of both sexes undergoing LLIF surgery atone or two levels inclusive of the L4-5 level.

Who may be able to join

  • At least 18 years of age at the time of planned surgery.
  • Indicated for 1- or 2-level instrumented LLIF surgery (in either prone or lateral decubitus positions), inclusive of the L4-5 disc space.
  • Written informed consent obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study.

Who cannot join

  • Patients requiring surgical treatment at more than 2 lumbar levels.
  • Patients with peripheral neuropathy such as from diabetes or other conditions that might affect the reliability of intraoperative neuromonitoring.
  • Patients with prior history of partial/full hip or knee joint replacement surgery (i.e., arthroplasty or resurfacing) on the leg targeted for saphenous monitoring and electrode placement.
  • Patients with presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data.
  • Female patients who are pregnant or wanting to become pregnant during the timeframe of study participation.
  • Patients participating in another clinical study which may compromise this study's results or compliance with this study's procedures.

About this study

Official title: Advanced Techniques in Intraoperative Monitoring for the Lateral Lumbar Interbody Fusion Procedure: a Utility Study

This study is designed to evaluate the clinical utility of a known intraoperative neuromonitoring modality (SSEP) using saphenous nerve as the site of stimulation to identify changes to the lumbar nerves which may be at risk during the lateral lumbar interbody fusion (LLIF) procedure.

Being tested
Somatosensory evoked potential [SSEP] intraoperative monitoring

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Somatosensory evoked potential [SSEP] intraoperative monitoringDiagnostic test

    No study specific intervention is performed. Intraoperative neuromonitoring system that is observed in this study is for assessing the health of the lumbar plexus during lateral lumbar interbody fusion surgery

What is being measured

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

  1. Sensitivity and specificity of SSEP neuromonitoring in post-operative clinical diagnosis of motor/sensory deficits

    This outcome measure determines the utility of the saphenous nerve SSEP monitoring based on the correlation of intraoperative neuromonitoring results with new or worsened postoperative neural deficits, as measured by motor and sensory physical exam.

    Measured: 6 weeks or until new or worsened neural deficits are resolved, but not exceeding 12 months.

Secondary outcomes (1)
  1. Determination of the positive predictive value (PPV) and negative predictive value (NPV) of free run and SSEP monitoring modalities.

    This outcome measure includes:

    • Correlating specific monitoring findings with incidence of new or worsened motor or sensory deficits post-operatively and their correlation with patient-specific and surgical factors.
    • Correlating patient and surgical factors with new and worsened postoperative neural deficits.

    Measured: 6 weeks or until new or worsened neural deficits are resolved, but not exceeding 12 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Intervertebral Disc Degeneration and Stenosis, Spinal, run by Alphatec Spine, Inc. 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 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: status not confirmed, as of the sponsor's last update on 24 Oct 2024. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity and specificity of SSEP neuromonitoring in post-operative clinical diagnosis of motor/sensory deficits (time frame: 6 weeks or until new or worsened neural deficits are resolved, but not exceeding 12 months.). 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 24 Oct 2024.
