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
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: A total of at least 100 patients from at least three sites will be enrolled based on inclusion/exclusion criteria. The retrospective chart review will include the full consecutive series of patients who received TLIF or PLIF surgery using the FlareHawk expandable interbody fusion cage between December 1, 2017, and May 31, 2018. Subjects from that consecutive series will be included in the study based on the pre-defined inclusion and exclusion criteria. All subjects will have been diagnosed with degenerative disc disease of the lumbar spine that required lumbar interbody fusion procedure at one or two levels as per the opinion of the treating surgeon. All subjects who meet the inclusion criteria and do not meet any of the exclusion criteria will be included in the study

Who may be able to join

  • To be a part of this study, the subject must:
  • Have been at least 18 years of age and skeletally mature at the time of surgery
  • Have had clinical and radiological evidence of degenerative disc disease of the lumbar spine
  • Have been treated with PLIF or TLIF surgery using the FlareHawk expandable interbody cage(s) at 1 or 2 contiguous levels from L2 to S1
  • Have been treated using the FlareHawk expandable interbody fusion cage, according to the approved labeling, between December 1, 2017, and May 31, 2018

Who cannot join

  • Subjects must not meet any of the following exclusion criteria to be included in the study:
  • Have a history of fusion surgery at the study level(s) prior to treatment with the FlareHawk device(s)
  • Have had spondylolisthesis unable to be reduced to grade 1 as part of the surgical procedure
  • Have had surgery with the FlareHawk device(s) at more than 2 levels
  • Have had surgery with the FlareHawk device(s) at levels outside the range of L2 to S1
  • Have been treated with any bone grafting material other than autogenous or allogenic bone graft in the FlareHawk device(s) and surrounding disc space
  • Have any contraindications listed in the approved labeling

About this study

Official title: Transforaminal/Posterior Lumbar Interbody Fusion With the FlareHawk® Expandable Interbody Fusion Device: A Retrospective Chart Review Study

This is a retrospective clinical study (chart review) of patients who have previously undergone Transforaminal Lumbar Interbody Fusion or Posterior Lumbar Interbody Fusion surgery with the FlareHawk expandable interbody fusion cage at one or two contiguous levels.

Read the detailed description

The purpose of this study is to evaluate the clinical outcomes of patients who have undergone a Transforaminal Lumbar Interbody Fusion (TLIF) or Posterior Lumbar Interbody Fusion (PLIF) procedure with a FlareHawk expandable interbody fusion cage(s) to assess the device's performance and safety when used in accordance with its intended use. The primary hypothesis is that study subjects who received the FlareHawk expandable cage(s) through a TLIF or PLIF procedure experienced fusion by 12 months (+/- 3 mo) follow-up, with improvements in clinical outcomes related to pain and/or disability compared to pre-operative scores. Further, the subjects are hypothesized to have not experienced any unforeseen device- or procedure-related adverse events.

What is being measured

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

  1. Radiographic Arthrodesis

    Proportion of participants with radiographic arthrodesis at 12 months +/- 3 months as determined using plain radiographic images with assessment based on the Bridwell-Lenke grading system [Bridwell and Lenke et al, 1995].

    Measured: 12 months +/- 3 months

Secondary outcomes (3)
  1. Change in Visual Analog Scale (VAS) for Leg Pain From Preoperative Baseline to Last Available Follow-up

    Visual analog scale for measuring pain intensity related to leg pain. The scale is anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 10).

    Measured: From baseline to last available follow-up, with an average follow-up of 4.6 ± 4.4 months (range: 0.5-20.5 mo)

  2. Change in Visual Analog Scale (VAS) for Back Pain From Preoperative Baseline to Last Available Follow-up

    Visual analog scale for measuring pain intensity related to back pain. The scale is anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 10).

    Measured: From baseline to last available follow-up, with an average follow-up of 4.4 ± 4.3 months (range: 0.5-20.5 mo)

  3. Change in Oswestry Disability Index (ODI) From Baseline to Last Available Follow-up

    ODI is used to quantify disability related to lower back pain. The final score/index ranges from 0-100. A score of 0-20 reflects minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled, and 81-100 bed-bound.

    Measured: From baseline to last available follow-up, with an average follow-up of 4.4 ± 3.8 months (range: 0.5-20.5 mo)

Questions about this trial

What is this clinical trial studying?

An observational study of Degenerative Disc Disease, run by Integrity Implants Inc. at 3 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 7 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: finished, as of the sponsor's last update on 21 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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?

Yes. Results are posted in the registry (first posted 14 Apr 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Radiographic Arthrodesis (time frame: 12 months +/- 3 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 21 Apr 2020.
