Case Report: Direct anterior approach with surgical hip dislocation for management of juvenile femoral head chondroblastoma: a case series and systematic review of the literature.

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: Femoral head chondroblastoma is a rare benign tumor in adolescents (10-20 years). Traditional surgeries face difficulties like poor exposure, high trauma, and risks of physeal injury/avascular necrosis (AVN). The DAA-SHD approach (no greater trochanteric osteotomy) is proposed for direct tumor resection, vascular preservation, and articular cartilage repair. Methods: A literature review (2005-2025) on adolescent femoral head chondroblastoma was conducted. Retrospective analysis of 4 cases (2014-2025) treated with supine DAA-SHD (same senior surgeon) autologous iliac bone grafting. Hip function was assessed via MSTS scale. Results: Mean follow-up: 64.75 months (9-124 months). All 4 cases had excellent/good MSTS scores (25-29 points). Imaging showed satisfactory bone graft healing; no AVN, recurrence, or limp/pain occurred. Conclusion: Supine DAA-SHD (no trochanteric osteotomy) is effective for adolescent femoral head chondroblastoma, enabling complete resection, anatomical reconstruction, and vascular protection. It enriches pediatric hip tumor treatment options but needs validation via large-scale prospective studies.
