About this trial

The Conduit cages are intended to restore the intervertebral height and to facilitate the intervertebral body fusion in the cervical and lumbar spine in skeletally mature patients with degenerative disc disease and instabilities at one or more levels of the spine. The Fibergraft Bioactive Glass (BG) is engineered to mimic the body's natural bone healing process. While previous studies have described the use of conduit cages in interbody fixation procedures, 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, and instabilities at one to multilevel contiguous levels between C2-T1 and 1-2 contiguous levels between L2-S1 of the spine with accompanying radicular symptoms, ruptured or herniated discs, and pseudarthrosis and spondylodesis. 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.

Age ≥ 18 years

Have a radiograph-based diagnosis of degenerative disc disease, ruptured or herniated discs,

Pathology of the cervical or lumbar spine.

Pathology to be between C2-T1 in the cervical group.

Disqualifiers

Patients < 18 years

BMI > 40 kg/m2 to be excluded

Patients with a bone density (DEXA) score of <2.0 to be excluded

3 or more levels for ACDF or Lumbar interbody to be excluded

Trial design

Design model

Case-only

Time perspective

Prospective

Treatments tested in this trial

  • Use of conduit cages and fibergraft BG Putty

    Device

    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.

Treatment groups

No treatment groups listed

Trial outcomes

Primary outcomes

1

Fusion

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

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

Secondary outcomes

1

Visual Analog Scale (VAS)

We will have patients fill out validated tools for PROs to assess how the patient is doing postoperatively

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

Oswestry Disability Index

We will have patients fill out validated tools for PROs to assess how the patient is doing

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

SF-12

We will have patients fill out validated tools for PROs to assess how the patient is doing

Time frame
