Robot-assisted total posterior arthroplasty (TOPS).

The authors describe the case of a patient with lumbar stenosis and neurogenic claudication who underwent a robot-assisted total posterior arthroplasty (TOPS [Total Posterior Spine] System) procedure. The TOPS is a motion-preserving implant that replaces the facet joints, allowing a wider decompression (when compared with laminectomy) and normal postoperative range of motion (as opposed to fusion), decreasing the risk of adjacent segment degeneration and the need for surgery in the future. The robot allows for precise placement of preplanned pedicle screws, allowing for accurate intraoperative device placement and decreased operative time. This patient returned to an active lifestyle without complications. The video can be found here: https://stream.cadmore.media/r10.3171/2025.4.FOCVID2517.
