Comparing unilateral and bilateral facetectomy in transforaminal lumbar interbody fusion: Impact on patient satisfaction and surgical outcomes.

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: This study investigates whether patient satisfaction, as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, clinical and radiographic outcomes differ between unilateral and bilateral facetectomy when performing transforaminal lumbar interbody fusions (TLIFs). Methods: We retrospectively reviewed 373 patients who underwent primary 1- or 2-level TLIF (2016-2023) at a tertiary care center; patients underwent unilateral ( Results: We found no significant differences in complication rates, reoperation rates, or radiographic outcomes between unilateral and bilateral facetectomy groups. HCAHPS scores showed no statistically significant differences in patient satisfaction across measured domains. Unilateral facetectomy was associated with a shorter hospital stay and more frequent use of minimally invasive techniques. Multivariable regression identified increased BMI associated with increased odds of postoperative infection and additional surgery. Increased operative time was associated with postoperative infection and intraoperative durotomy. Finally, increased length of stay was associated with increased odds of intraoperative durotomy and instrumentation failure. Conclusion: For TLIF, unilateral versus bilateral facetectomy provided comparable clinical and radiographic outcomes, with no significant differences in patient satisfaction.
