Surgical outcomes in adult scheuermann's kyphosis: a matched-cohort comparison with adult idiopathic scoliosis as a clinical benchmark.
Article in Spine deformity, 2026. 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
purposeSurgical treatment for Scheuermann's Kyphosis (SK) in adolescents is well-established, but its role in adults remains controversial. This study challenges the traditional non-operative stance by evaluating the clinical outcomes of surgery in adult SK patients, using a matched cohort of adult idiopathic scoliosis (Adult IS) patients as a clinical benchmark.
methodsA retrospective, 1:3 matched-cohort study from a multicenter database with a minimum 2-year follow-up. Thirty-three SK patients were matched with 99 Adult IS patients by age and number of instrumented levels. Demographics, radiographic parameters, surgical data, complications, and patient-reported outcome measures (PROMs) were analyzed.
results33 SK patients and 99 patients from the Adult IS comparative cohort were included. Mean age was 32.1 years; 82.8% of Adult IS patients and 39.4% of SK patients were female. Mean preoperative kyphosis in SK was 74.9°, and the mean Cobb angle in Adult IS was 66.3°. The SK cohort presented with significantly worse baseline mental health scores (p = 0.015). Despite requiring more posterior column osteotomies (51.5% vs. 27.2%, p = 0.012), the SK cohort showed no significant increase in surgical time or blood loss. Both groups improved in all PROMs, with significantly greater mental health gains in SK (p = 0.03). Major complications (21.2% vs. 19.2%, p = 0.790) and reinterventions (21.2% vs. 18.2%, p = 0.719) were comparable.
conclusionSurgical correction of Scheuermann's kyphosis in young adults is safe and effective, leading to significant functional and psychological improvements, particularly in mental health. Complication rates and surgical complexity were comparable to adult idiopathic scoliosis surgery. Surgical treatment is a viable option for appropriately selected adult SK patients. LEVEL OF EVIDENCE: III.
