This prospective, post-market, open label clinical study is designed to examine the lumbar fusion rate at 24 months post operative in subjects who have undergone a lumbar fusion surgery using Trinity Elite with or without local bone.
Condition or disease
Degenerative Disc Disease
Biological: Trinity Elite
The study is a prospective, post-market, open label clinical study. Up to 10 sites across the United States, with a minimum enrollment of 120 subjects study-wide, will be enrolling subjects. The primary objective of this study is to measure the lumbar fusion rate in subjects at 24 months when lumbar arthrodesis is performed using Trinity Elite with or without local bone. Surgical approach (PLF, TLIF,ALIF, XLIF, etc.) is according to the physician's discretion, but must comply with FDA approved/cleared indication for use and labeling. The primary endpoints are radiographic evidence of fusion and the absence of serious adverse events attributable to Trinity ELITE. The secondary objectives of this study are to measure the clinical and economic outcomes when posterolateral arthrodesis is performed using Trinity Elite and/or local bone with supplemental pedicle screw fixation.
lumbar fusion by CT scan following arthrodesis using Trinity Elite [ Time Frame: 24 months ]
CT scan of the lumbar vertebral column will be used to determine the fusion status of the spine after Trinity Elite was used in the lateral gutters and in the facet joints. The number of bridging bony cortices will be recorded by blinded reviewers and tabulated. The data will be reported as n
number of participants with treatment related adverse events [ Time Frame: 24 months ]
AEs collected on an ongoing basis, reviewed by the Investigators and medical monitor

Accepts Healthy Volunteers:
age >= 18 years of age
Subject must be 18 years of age (≥ 18 years) or older at the time of consent.
Subject must have a documented diagnosis of DDD. DDD is defined by back and/or radicular pain with degeneration of the disc as confirmed by medical history, physical examination, and radiographic studies that may include CT, MRI, plain X-ray film, discography, myelography, etc. with one or more of the following findings:
Instability as defined by >3mm translation or >5 degrees angulation
Osteophyte formation of facet joints or vertebral endplates
Decreased disc height, on average by >2mm, but dependent upon the spinal level
Scarring/thickening of ligamentum flavum, annulus fibrosis, or facet joint capsule
Herniated nucleus pulposus
Facet joint degeneration/changes; and/or
Subject may have up to a Grade 2 Spondylolisthesis of the lumbar spine with clinical manifestations of one or more of the following phenomena:
Subject must require lumbar arthrodesis at 1-4 contiguous levels (L1-S1) for a PLF approach and 1-2 contiguous levels for an interbody approach.
Subject must have been unresponsive to conservative care for at least 6 months prior to fusion surgery.
7. Subject must agree not to use electromagnetic adjuncts to enhance bone fusion during the course of the study 8. Subject must be willing and able to sign an informed consent document. 9. Subject must be willing and able to return for all follow-up visits, agree to participate in postoperative clinical and radiographic evaluations and comply with the required study regimen.
