Comparison of short-segment vs. long-segment fixation in posterior osteotomy for kyphotic deformity: effects on postoperative alignment and complications.

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: Posterior osteotomy is an effective treatment for severe kyphosis; however, postoperative complications, particularly early radiographic proximal junctional kyphosis (PJK), may compromise outcomes. Evidence regarding factors influencing postoperative efficacy and complication risk remains limited. Objective: To compare the clinical efficacy of long-segment vs. short-segment fixation in posterior osteotomy for kyphosis and identify factors affecting outcomes and complications. Methods: This retrospective controlled study included 150 patients undergoing posterior thoracolumbar osteotomy with fusion and internal fixation between June 2019 and June 2023. Patients were grouped by fixation length: long-segment (group L, ≥5 segments) and short-segment (group S, ≤4 segments). Propensity score matching balanced baseline characteristics, yielding 50 patients per group. Radiographic parameters (Cobb angle, sagittal vertical axis), perioperative data, and 12-month complications were recorded. Pain and function were assessed using VAS and ODI. Multivariate logistic regression identified independent risk factors for correction loss and early radiographic PJK. Results: Both groups showed significant postoperative improvement in Cobb angle and sagittal alignment ( Conclusion: When correcting spinal kyphosis via posterior osteotomy, long-segment fixation better maintains correction and reduces complications like early radiographic PJK, while short-segment fixation shortens surgery time but increases risks of correction loss and early radiographic PJK.
