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. Result: 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 f emoral head chondroblastoma, enabling complete resection, anatomical reconstruction, a nd vascular protection. It enriches pediatric hip tumor treatment options but needs vali dation via large-scale prospective studies.
