3 spine studies to know


Becker's reported on three key spine studies since April 28.

1. Amplify Surgical saw positive results in a clinical study for its DualPortal endoscopic technique. Researchers analyzed 3,673 cases that used the technique for decompressions, discectomies and transforaminal lumbar interbody fusions. The study concluded dualPortal was safe and had favorable outcomes and a low complication profile.

 2. Relievant Medsystems has announced four-year results from two clinical trials demonstrating the safety, effectiveness and durability of its Intracept procedure for patients with vertebrogenic pain. The study, led by Jad Khalil, MD, associate professor of orthopedic surgery and director of the spine surgery fellowship at Beaumont Hospital in Royal Oak, Mich., included 94 patients who were successfully treated with the Intracept procedure. The study found that 66.7 percent fewer were actively taking opioids for pain compared with the baseline, 83 percent of patients were satisfied with the procedure, 71 percent of patients had resumed the same level of activity as before the procedure, and no serious device-related adverse events were reported. 

3. Cervical disc replacement compared to anterior cervical discectomy and fusion did better at 10 years, according to a study in the International Journal of Spine Surgery.The study compared disc replacement using Zimmer Biomet's Mobi-C with ACDF across three centers. A total 155 patients were enrolled in the study, and composite success scores for the disc replacement group was 62.4 percent. The ACDF group had a composite success score of 22.2 percent.
