Traditional Dual Growing Rods With 2 Different Apical Control Techniques in the Treatment of Early-Onset Scoliosis

Objective: Based on traditional dual growing rods (TDGR), apical control techniques (ACTs) were introduced as adjuvant procedures to improve deformity correction at the apex segment in treatment of early-onset scoliosis (EOS). We aimed explore whether TDGR+ ACTs have different indications, attain more correction, negative effects spinal growth, and complications.Methods: Between 2004 2019, a retrospective study EOS patients treated with TDGR or without was conducted divided into 3 groups: group; hybrid technique (HT) group: Vertebrectomy/hemivertebrectomy short fusion TDGR; ACPS convex pedicle screws (ACPS) TDGR. Demographic, radiographic parameters, clinical outcomes, complications, revisions analyzed compared.Results: Seventy-eight enrolled. The preoperative main curve largest HT group. group had smallest residual (19° ± 8.9°) vertebral translation (12.0 9.0 mm) latest follow-up, followed by (30° 17.4°, 22.1 13.4 13.2°, 32.8 17.1 mm). T1–12 height T1–S1 after index surgery. Complications groups lower than Scoliosis Research Society-22 self-image questionnaire superior group.Conclusion: According our intermediate results, TDGR+ACTs could ability deformity. little deleterious during lengthening procedures, complication rate might be supplemental option for suitable patients.
