|Late-Breaking Study Provides Evidence to Support Beneficial Seven-Year Clinical Outcomes and Patient Satisfaction for 2-Level Prestige LP(TM) Cervical Disc Patients|
Study Represents Longest Patient Follow-Up Data for U.S. 2-Level Cervical Disc Patients
DUBLIN and CHICAGO - May 3, 2016 - Medtronic plc (NYSE: MDT) today announced results of seven-year follow-up data demonstrating favorable clinical outcomes and patient satisfaction for the 2-level Prestige LP(TM) Cervical Disc compared to 2-level anterior cervical discectomy and fusion (ACDF). The Prestige LP Disc - currently indicated for single-level cervical disc disease causing nerve or spinal cord compression from C3-C7 - is pending FDA PMA approval for 2-level use. The device is designed to preserve motion in the neck at the operated disc level, unlike a fusion surgery that does not allow for motion. The Prestige LP Disc is the third clinically-proven artificial cervical disc in Medtronic's portfolio. The Prestige LP Disc has a ball-and-trough design and moves in a range of motions, including bending, rotation and translation.
The data will be presented today during the late-breaking session at the 84th Annual Meeting of the American Association of Neurological Surgeons (AANS) in Chicago, IL by Todd Lanman, M.D., a neurosurgeon at the Cedar-Sinai Institute for Spinal Disorders in Los Angeles, CA.
"The seven-year results of this study show that the patients receiving 2-level cervical disc replacement exhibited beneficial clinical outcomes and maintained them over time," said Dr. Lanman. "At 84 months, the patients treated with the 2-level Prestige LP Disc demonstrated greater rates of overall success compared to the 2-level ACDF patients."
The randomized controlled investigational device exemption (IDE) trial included a total of 397 study subjects (209 investigational and 188 control) and compared results up to seven years. Key findings of the statistical analysis at seven years show that the 2-level Prestige LP Disc patients:
Risks of the Prestige LP Disc include, but are not limited to: bone formation (including heterotopic ossification) that may reduce spinal motion or result in a fusion, either at the treated or at adjacent levels.
"This is the longest follow-up data available on clinical study patients treated with 2-level cervical arthroplasty in the United States," said Tommy Carls, vice president of Research and Development for the Spine division, which is part of the Restorative Therapies Group at Medtronic. "We're committed to developing meaningful innovations - like the Prestige LP Disc - that fundamentally change patients' lives. That's why it's exciting to see that the patients treated with the Prestige LP Disc maintain their outcomes for seven years."
