LEWISVILLE, Texas--(BUSINESS WIRE)--Orthofix International N.V. (NASDAQ: OFIX), a diversified, global medical device company, today announced the print publication of a 12-month study of patients that have undergone single-level anterior cervical discectomy and fusion (ACDF) with Trinity Evolution® in combination with a PEEK interbody spacer and supplemental anterior fixation. Published in the European Spine Journal, the data demonstrates the effectiveness of the bone graft with patient fusion rates of 78.6 percent at 6 months and 93.5 percent at 12 months. Seventy-five percent of the study participants were current or former smokers, diabetic, overweight, obese or extremely obese and considered to be at high risk for bone growth failure.
“To alleviate pain and neurological deficits resulting from nerve compression caused by degenerative disc disease, the most common recourse is surgical decompression through an anterior approach followed by the insertion of a structural interbody spacer filled with bone graft material,” said Dr. Timothy A. Peppers, at Scripps Hospital and a co-author of the journal article. “This study demonstrated the effectiveness of Trinity Evolution in achieving a solid fusion when used in this manner, indicating that it is a viable option for patients needing anterior cervical discectomy and fusion.”
This prospective, multi-center, clinical study was designed to evaluate the effectiveness of Trinity Evolution, a viable cellular bone allograft in patients undergoing a single level fusion at the vertebral locations between C3/C4 and C6/C7. Trinity Evolution was placed within and around each Orthofix PEEK interbody spacer to promote bone growth.
“We are committed to investing in meaningful clinical research to aid physicians in their treatment decisions,” said Orthofix Chief Scientific Officer James Ryaby, Ph.D. “These results are important as they further substantiate that Trinity Evolution is effective even in challenging patient populations who might not respond well to traditional allograft and autograft materials.”
The primary endpoint was radiographic fusion status based on independent review of CT scans and radiographic review of angular motion. The criteria for fusion was the presence of bridging bone across the adjacent endplates as seen on thin cut CT scans in addition to angular motion from flexion/extension X-rays.
In addition, secondary endpoints were measured including function as assessed by the Neck Disability Index and neck and arm pain as assessed by individual Visual Analog Scales (VAS). Neck function and neck/arm pain were found to significantly improve at both 6 and 12 months. There were no serious adverse events attributable to Trinity Evolution as determined by an independent consultant.
Processed by the Musculoskeletal Transplant Foundation (MTF), a nonprofit organization dedicated to providing quality tissue, Trinity Evolution is a cryopreserved allograft that consists of cancellous bone with viable cells retained within that matrix and a demineralized cortical bone component. It possesses all three of the key properties for successful bone grafting, which makes it an ideal autograft substitute.
“MTF is committed to research to ensure innovative clinical options exist for all patients,” said Bruce Stroever, President and Chief Executive Officer of MTF. “We are pleased these results support the use of a high quality MTF allograft like Trinity Evolution to augment the patients’ recovery.”
Trinity Evolution is the predecessor of Trinity ELITE®, a moldable bone graft material that enables physicians to easily control the placement of tissue during procedures. To date there have been more than 150,000 procedures using Trinity Evolution and Trinity ELITE.
