The hidden asymmetry: facet joint tropism as a clue to spinal malalignment and muscle degeneration in adult spinal deformity.
Article in Spine deformity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThe role of facet joint tropism (FJT) in degenerative spinal disorders such as disc herniation, spondylolisthesis, and lumbar canal stenosis is well-established. However, its association with adult spinal deformity (ASD) remains underexplored. Hence, we aim to study the correlation of FJT with spinopelvic parameters and lumbar paraspinal muscle morphology in ASD patients. MATERIALS AND
methodsWe analysed 117 patients with ASD from 2021 to 2024. An absolute value difference (ΔFJA) of more than 10 degrees between the right- and left-facet joint angle (FJA) was defined as FJT. We considered patients with FJT at the apex vertebra as the FJT + group and with ASD but without FJT as the FJT- group.
resultsThe mean ΔFJAs between the FJT + (n = 45) and FJT- (n = 45) were 17.14 and 5.38, respectively. For Cobb angle (CA) > 40˚ (n = 13), 84.6% (n = 11) belonged to the FJT + group. For CA 10-19˚(n = 28), 78.6% (n = 22) belonged to the FJT- group. Of the radiological parameters, differences in CA (p = 0.012), pelvic incidence (PI) (p = 0.031), grades of vertebral body rotation (VBR) (p = 0.022), facet joint osteoarthritis grades (FJOA) (p = 0.040) and cross-sectional area (CSA) of concave multifidus muscle (MF) (p = 0.010) were statistically significant between both the groups. The CSA of MF was decreased on the concave side (2.45 cm
conclusionsPatients with ASD and FJT exhibited greater Cobb angle, higher PI, higher grades of FJOA and VBR, and lower CSA of concave MF. However, the role of facet joint tropism in adult spinal deformity-whether causal or compensatory-warrants validation through longitudinal, long-term studies. LEVEL OF EVIDENCE: Level III.
