Impact of Paravertebral Muscle Degeneration on Residual Low Back Pain Following Percutaneous Kyphoplasty for Osteoporotic Vertebral Fractures: A Retrospective Study.

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: Residual low back pain (LBP) is frequently reported after percutaneous kyphoplasty (PKP) for osteoporotic vertebral fractures (OVFs), yet its underlying mechanisms remain unclear. Paravertebral muscles (PVMs) degeneration, particularly fat infiltration and atrophy may contribute to persistent postoperative pain. Objective: To evaluate the association between PVMs degeneration and residual LBP after PKP and identify imaging-based predictors for risk stratification. Methods: This retrospective cohort study included 213 patients (mean age 70.88 ± 8.58 years; 82.2% female) with single-level OVFs who underwent PKP between January 2021 and June 2023. Patients with multiple-level fractures, chronic LBP, neurological deficits, prior spinal surgery, incomplete imaging, or inadequate follow-up were excluded. Fat infiltration percentage (FI%) and cross-sectional area of the multifidus (MF), erector spinae (ES), and psoas major (PS) were measured at the L4 level using transverse T2-weighted MRI. Residual LBP was defined as postoperative VAS ≥3.5 at 12-month follow-up. Logistic regression and ROC analyses were conducted and appropriate univariate tests ( Results: Residual LBP occurred in 13.6% of patients and was associated with higher VBQ scores (3.14 ± 0.38 vs 2.57 ± 0.25, P=0.001), greater postoperative kyphosis (16.03 ± 6.69° vs 6.70 ± 4.80°, Conclusion: Preoperative magnetic resonance imaging assessment of paravertebral muscle may help identify patients at risk for residual low back pain after kyphoplasty. Incorporating preoperative imaging and postoperative physical therapy referral may improve patient outcomes.
