Repeated Vertebral Column Resection (Re-VCR) in Congenital Scoliosis With Curve Progression After Instrumentation Removal.
Article in Orthopaedic surgery, 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
objectiveTo evaluate the surgical efficacy of repeated vertebral column resection (Re-VCR) after instrumentation removal in congenital scoliosis (CS) patients previously undergoing primary posterior spinal correction with VCR, and to analyze complications pertinent to revision surgery.
methodsIn this retrospective cross-sectional study, a total of 16 CS patients who underwent Re-VCR following instrumentation removal between February 2013 and February 2022 were reviewed. Radiographic parameters were assessed pre- and post-primary operation, pre-removal, pre- and post-revision and at the last follow-up. Clinical data were also analyzed and recorded for each patient.
resultsThe indications for instrumentation removal were infection, implant failure, patient and family request, and persistent pain. The Cobb angle of the main curve, global kyphosis (GK), coronal balance (CB) and sagittal vertical axis (SVA) significantly progressed after instrumentation removal. The average progression rates of scoliosis and kyphosis were 5.3° ± 4.0°/year and 10.0° ± 7.2°/year. Following revision surgery, the Cobb angle of the main curve, GK, CB showed significant improvement (t = 10.694, p < 0.001; Z = -3.516, p < 0.001; Z = -2.664, p = 0.008). For Re-VCR, the average extension of the fusion level was 2.9 ± 1.4 vertebrae proximally, 3.0 (2.0, 3.0) vertebrae distally and 5.4 ± 1.6 vertebrae in total. The average correction rates of the Cobb angle of the main curve and GK were 59.5% ± 23.4% and 53.7% ± 18.3% with no significant correction loss during follow-up (p > 0.05). Compared with pre-revision, the mean scores of pain, satisfaction, mental health and self-image on the Scoliosis Research Society-22 (SRS-22) questionnaire improved at different levels. Intra-revision complications included alert of neurophysiological monitoring and dural tear, while breakage of the distal L5 pedicle screw occurred in 1 (6.3%) patient 2 years after revision.
conclusionsSevere progression of deformity and trunk imbalance was frequently observed following instrumentation removal. The removal of instrumentation is not routinely recommended, and revision surgery employing Re-VCR frequently necessitates an extension of the fusion level. Satisfactory radiographic and clinical outcomes following Re-VCR were effectively maintained throughout the follow-up period, but great caution should be exercised during Re-VCR.
