Comparing two methods for cervical spine surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study observes the outcomes of patients undergoing anterior cervical discectomy and fusion (ACDF) using either Tritanium C or structural allograft bone. It includes a retrospective cohort of patients treated with structural allograft and a prospective cohort of patients receiving Tritanium C. The study aims to compare the rate of fusion success and adverse events between these two groups. Data will be collected from medical records and follow-up visits to assess radiographic outcomes and patient-reported outcomes.

4. Subject has received six weeks of non-operative therapy i.e. injections, physical therapy, oral steroids
5. Subject understands the conditions of enrollment and is willing to sign and date the Informed Consent (Prospective study)
6. Subjects that will prospectively undergo one or two level anterior cervical discectomy and fusion with Tritanium C (Prospective study)
7. Subjects that underwent one or two level anterior cervical discectomy and fusion with either standard of care structural allograft bone at any AHN facility from 01/01/2016 to 08/14/2023 (Retrospective study) • Note that these patients will be followed for a maximum of one year (up to 08/14/2024 for a patient enrolled at the end of this inclusion period)

Exclusion Criteria:

Patients may not be enrolled in the study if any of the following exclusion criteria are present:

1. Presence of an infection systemic or local
2. Presence of marked local inflammation
3. Subject has any abnormality present which affects the normal process of bone remodeling including, but not limited to, severe osteoporosis involving the spine, bone absorption, osteopenia, primary or metastatic tumors involving the spine, active infection at the site or certain metabolic disorders affecting osteogenesis
4. Use of bone growth stimulator
5. Subject has prior fusion at the levels to be treated
6. Subject has any neuromuscular deficit
7. Subject has any condition of senility, mental illness, or substance abuse
8. Subject has any other medical or surgical condition which would preclude the potential benefit of spinal implant surgery in the judgement of the PI
9. Subject has rapid joint disease, bone absorption, osteopenia, osteomalacia, and/or osteoporosis. Subject is pregnant or plans to become pregnant during the course of the study.
10. BMI≥40 kg/m2
11. Subject uses chronic corticosteroids
12. Subjects with current active psychiatric diagnosis or a personality disorder likely to interfere with the study
13. Subjects who smoke and do not plan to quit
