[3] The TOPS System replaces the bony and soft tissue removed during spinal decompression surgery and implants them at the affected spine segment to aid the patient's flexibility.
Comparatively, Premia Spine's follow-ups over five years in Belgium and Israel suggest that the TOPS System yields significantly better outcomes, with a preoperative complication rate under five percent.
[16] In July 2021, Jared Ament presented the clinical and economic evidence supporting the TOPS facet arthroplasty system at the Spine Summit, San Diego, demonstrating its cost-effectiveness compared to TLIF for treating spondylolisthesis and spinal stenosis.
[17][18][19] In November 2021, its intermediate clinical study results, presented at the Society for Minimally Invasive Spine Surgery (SMISS) supported the use of the TOPS System for lumbar spinal stenosis and degenerative spondylolisthesis.
The study also noted that the TOPS System uniquely helps patients maintain natural sagittal balance, offering new options for non-fusion treatment of degenerative spondylolisthesis and spinal stenosis.
[27] In September 2022, Dr. Dom Coric and colleagues published a study in the Journal of Neurosurgery Spine, which demonstrated that the TOPS System, a motion-preserving treatment for lumbar stenosis with degenerative spondylolisthesis, outperformed TLIF in clinical success rates.
