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.

Interventions

DEVICEUse of Viper Prime/Expedium system with Fibergraft BG Putty

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.

Design outcomes

Primary

MeasureTime frameDescription
Fusion2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)We will assess fusion with regular x-rays and CT scans at 1 and 2-year postoperatively.

Secondary

MeasureTime frameDescription
Visual Analog Scale (VAS)2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)We will have patients fill out validated tools for PROs to assess how the patient is doing postoperatively
Oswestry Disability Index (ODI)2 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)We will have patients fill out validated tools for PROs to assess how the patient is doing postoperatively
Short form survey-122 years (At baseline, postoperatively at 6 weeks, 3 months, 6 months, 12 months, and 24 months)We will have patients fill out validated tools for PROs to assess how the patient is doing postoperatively
