Brief Summary

The Viper Prime/Expedium spine systems are intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracolumbar and sacral spine. The Fibergraft Bioactive Glass (BG) is engineered to mimic the body's natural bone healing process. While previous studies have compared the use of Viper prime/Expedium spine system in minimally invasive and open surgeries, these studies did not specifically study the clinical and radiographic outcomes of patients who have received these implants in addition to Fibergraft. We aim to recruit patients with degenerative disc disease, spondylolisthesis, trauma, and/or pseudarthrosis who require spine surgery under standard of care and use these implants. We will then follow these patients for a duration of two years to report their clinical and radiographic outcomes to determine fusion, complication rate, and revision surgeries if any.

Outcome Measures

Primary Outcomes (1)

  • Fusion

    We will assess fusion with regular x-rays and CT scans at 1 and 2-year postoperatively.

    2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)

Secondary Outcomes (3)

  • Visual Analog Scale (VAS)

    2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)

  • Oswestry Disability Index (ODI)

    2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)

  • Short form survey-12

    2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)

Interventions

Patients who require spine surgery under standard of care and meet the inclusion and exclusion criteria identified, will be recruited from clinic. Consent for participation in study will be signed at the same time as consent for surgery. All PROMs and scans will be done as standard of care and data will be obtained through chart review for this study.

Study Population

Adult patients with spinal conditions mentioned in inclusion/exclusion criteria

You may qualify if:

  • Age ≥ 18 years
  • Have a radiograph-based diagnosis of degenerative disc disease, spondylolisthesis, spinal trauma (i.e., fracture or dislocation), spinal stenosis, or deformity (i.e., scoliosis, kyphosis, and/or lordosis), spinal tumor, or pseudoarthrosis/failed fusion.
  • Pathology of the thoracolumbar or sacral spine.
  • Patients requiring fusion of 1-3 levels
