Clinical, Radiological, and Functional Evaluations of the Anterior-to-Psoas Lumbar Interbody Fusion Approach With Posterior Decompression and Osteotomy for Treating Patients With Adult Spinal Deformity: A Retrospective Study.
Article in Cureus, 2025. 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
objectiveDegenerative adult spinal deformity (ASD) is a prevalent disease in the elderly population. Treating it typically requires an extensive surgical intervention. This study aimed to assess the use of expandable spacers for multi-level anterior-to-psoas lumbar interbody fusion (ATP-LIF) along with posterior direct decompression and osteotomy to treat patients with degenerative ASD.
methodThis was a single-center retrospective study of ASD patients (anyone undergoing fusion procedure for four or more spinal levels) undergoing two-stage surgery with expandable interbody spacers with a minimum follow-up period of around 12 months between November 2019 and June 2021. A total of 20 patients were enrolled in this study (15 patients = four-level fusion, five patients = five-level fusion). Exclusion criteria included <18 years of age, pregnancy, tumor, and trauma patients. Demographic, surgical, radiographic, complications, and patient-reported outcomes (PROs) were collected.
resultsOf the 20 patients included (mean age = 68.1 ± 9.0 years, mean body mass index = 30.5 ± 7.4 kg/m
conclusionTwo-stage ATP-LIF with expandable spacers along with posterior direct decompression and Ponte osteotomy is a viable minimally invasive treatment for patients with ASD. This was evidenced by similar surgical outcomes to pedicle subtraction osteotomy, improvements in PROs, restoration of PI-LL, high fusion rates, and a significant increase in disc height.
