Trinity Evolution in Posterior or Transforaminal Lumbar Interbody Fusion (PLIF/TLIF)
This trial is active, not recruiting.
|Condition||degenerative disc disease|
|Start date||September 2009|
|End date||June 2014|
|Trial size||200 participants|
|Trial identifier||NCT00965380, CP-01006B|
The purpose of this study is to utilize Trinity Evolution in conjunction with an interbody spacer and supplemental posterior fixation of the surgeon's choice and to follow the patients to measure the clinical outcomes and rate of fusion. The hypothesis of the study is that Trinity Evolution combined with an interbody spacer and supplemental posterior fixation will result in fusion rates and clinical outcomes similar to those with other routinely used autograft and allograft materials including: fusion, improvement in pain and function, maintenance of lower extremity neurological function, and absence of serious adverse events related to the use of the Trinity Evolution product.

|Official title||A Radiographic and Clinical Study Evaluating a Novel Allogeneic, Cancellous, Bone Matrix Containing Viable Stem Cells (Trinity Evolution™ Viable Cryopreserved Cellular Bone Matrix) in Posterior Lumbar or Transforaminal Lumbar Interbody Fusion (PLIF or TLIF)|
|Description||Degenerative disorders of the lumbar spine can lead to a multitude of clinical problems including back pain and/or leg pain secondary to nerve compression and/or deformity. When conservative (non-surgical) treatment fails after at least a 6 month period and/or non-operative treatment is not indicated, patients and physicians may turn to a surgical solution. Surgical options consist basically of decompressing nerves, correcting and/or stabilizing deformities if required and fusing the segment, depending on the clinical situation. The "gold standard" for aiding healing in spinal fusion surgeries is the harvesting of autograft from the patient's iliac crest and placing it in and around the segments of the spine that are intended to be fused. Autograft is considered the "gold standard" because it contains the essential elements required for successful bone grafting: osteogenesis, osteoconduction, and osteoinduction. However, the morbidity of harvesting autograft has been well documented and includes chronic donor-site pain, infection, neurologic injury, blood loss, deformity, bowel injury, hernia, and prolonged surgical and hospitalization time. There are now a number of products on the market to minimize or replace the use of autograft. However, few of these products contain all three essential bone-forming elements (osteogenesis, osteoconduction, and osteoinduction) in a single, stand alone product. Trinity Evolution is a novel, allogeneic cancellous bone matrix containing viable osteoprogenitor cells, mesenchymal stem cells and a demineralized cortical bone (DCB) component to provide the required osteoconduction, osteogenesis, and osteoinduction necessary for successful bone grafting. Preclinical studies with Trinity Evolution have demonstrated in-vitro and in-vivo safety and effectiveness. Trinity Evolution is considered an allograft and as such is a "minimally manipulated" tissue and is labeled for bone repair for spinal, orthopedic and podiatric indications where autograft is used. The dosage will be dependent upon the specific requirements of the case.|
