摘要: Objective The mechanical alteration in the adolescent/pediatric cervical spine after spinal fusion remains unknown. purpose of this study was to investigate morphologic changes patients who underwent fusion. Methods Ten (9–18 years) were included. anteroposterior diameter (AP-D) vertebral body evaluated using lateral radiographs. AP-D ratio defined as at final follow-up postoperative value. kyphosis angles fused level and (C2–C7) also measured. Results mean period 20.0 years (range, 12–40 years). reduced 4 increased or remained unchanged 6 patients. reduction usually seen middle levels remarkable correction posterior instrumentation combined with anterior significantly correlated segments (P = 0.029) angle 0.016). Conclusions Cervical endplate destruction by bone grafting is a risk factor for atrophic Endplate instrumentation-induced stress shielding could alter remodeling.
