Outcome Measures

Primary Outcomes (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 \[Bridwell and Lenke et al, 1995\].

    12 months +/- 3 months

Secondary Outcomes (3)

  • Change in Visual Analog Scale (VAS) for Leg Pain From Preoperative Baseline to Last Available Follow-up

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

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

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

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

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

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

You may qualify if:

  • 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

You may not qualify if:

  • 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
