An FDA study found that Premia Spine's TOPS system saw better clinical results than spinal fusion for spinal stenosis and spondylolisthesis patients.
The study, published in the Journal of Bone and Joint Surgery, included 321 patients, according to a June 25 news release from the devicemaker.
Researchers found that 73.5% of patients who had surgery with the TOPS arthroplasty system reached composite clinical success at 24 months postoperatively compared to 25.5% in the fusion group. The arthroplasty group also outperformed the fusion group in most patient-reported outcome measures, and the fusion group had higher rates of symptomatic adjacent segment degeneration and revisions.
