Clinical Trial Summary

A single center study of clinical and radiological outcomes in a retrospective cohort of patients treated with Lumbar Interbody Fusion augmented with Prosidyan Fibergraft for 1 or 2 level degenerative spinal disease by a single surgeon. Study Design: Retrospective chart review with prospective data collection.


Description:

Background and Rationale: Degenerative pathologies of the lumbar spine including degenerative disc disease, spondylosis and spondylolisthesis are the leading indications for lumbar interbody fusion (LIF) among low back pain patients. Prosidyan's Fibergraft is a bioactive synthetic bone graft substitute that is ultraporous and made from bioactive glass fibers. The proposed study will be an analysis of clinical outcomes among patients who underwent lumbar interbody fusion augmented with Prosidyan Fibergraft by a single surgeon. Objective(s): PRIMARY: To assess the fusion rate in this retrospective cohort at 12 months post-operatively. SECONDARY: - To report and analyze trends (if any) among diagnosis, number of levels, approach (TLIF, LIF or ALIF) and fusion status. - To assess pain and functional health changes pre to post-operatively. SAFTEY: To report the rate of surgical adverse events and subsequent surgeries at the operative level. Study design: Retrospective chart review with prospective data collection. Procedures: Patients will be screened by retrospective chart review. Eligible patients will be contacted and asked to participate. Consenting patients will answer questionnaires and undergo a CT lumbar scan. Study Product / Intervention: The device under investigation is Prosidyan Fibergraft. However, since study subjects are retrospectively enrolled, they will have received the device before entering the study.

Outcome

Type Measure Description Time frame Safety issue
Primary Fusion Rate The primary outcome for this study will be the overall fusion rate in the retrospective cohort. Fusion will be assessed from a Lumbar CT scan. The criteria used to assess fusion status will be according to the scale developed by Brantigan, Steffee, and Fraser (BSF criteria). 12 months post-operatively
Secondary Mean change in Visual Analog (VAS) Pain scale Mean change in low back pain as measured by a 100 mm Visual Analog Scale where 0 indicates no pain and 100 indicates the greatest pain. Pre-operatively to 12 months post-operatively
Secondary Mean change in Oswestry Disability Index (Function) score Mean change in low back functional status as measured by the Oswestry Disability Index where a score of 0 indicates no disability and a score of 100 represents maximum disability Pre-operatively to 12 months post-operatively
