Demonstrating the feasibility of facet arthroplasty using the Total Posterior Spine System (TOPS) in the ambulatory surgery center (the TOPS outpatient experience).
Article in Journal of spine surgery (Hong Kong), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The transition to the outpatient/ambulatory setting is especially important within value-based care system. While some procedures are well supported, posterior motion-preserving technologies, such as Total Posterior Spine System (TOPS), a novel artificial facet replacement, have yet to be evaluated in an ambulatory surgery center (ASC) setting. The objective of this study is to assess the feasibility, safety and early outcomes of the TOPS device in an ASC setting. Methods: In this retrospective case series, we reviewed 30 consecutive patients who underwent TOPS implantation at a free-standing ASC between September 2023 and December 2025. Demographics, intra-operative metrics, discharge data, 90-day events and patient-reported outcome measures (PROMs) were collected from operative/anesthesia reports and the electronic medical record. Results: Thirty patients were included; 14 males and 16 females, with a mean age and body mass index (BMI) of 62 years and 27±5 kg/m Conclusions: This series demonstrates that TOPS facet arthroplasty can be safely and effectively performed in a free-standing ASC.
