研究设计。回顾性放射学研究。目的。旨在调查接受双生长棒 (DGR) 治疗的早发性脊柱侧凸 (EOS) 患者远端器械椎体 (DIV) 周围椎骨的生长情况。背景数据摘要。先前的研究表明，DGR 可能会保护甚至刺激脊柱生长。但有关生长棒对个体椎体生长影响的报道却很少。纳入接受 DGR 治疗、至少进行过 4 次延长治疗并随访 5 年的 EOS 患者。对初次手术和最终随访时的脊柱X光片进行了审查。测量DIV-2至DIV+2椎体的高度、宽度和深度以及邻近椎间隙（IVS）的高度。计算生长百分比。结果。 31 名患者（平均年龄，6.2 +/- 2.5 岁）符合纳入标准，其中 74.2% (23/31) 为女性。平均随访时间为 6.2 年（范围：5.0-10.4 年）。测量的椎骨分为 DIV 组（n = 65）、DIV-组（DIV-1 和 DIV-2，n = 60）和 DIV+ 组（DIV+1 和 DIV+2，n = 47）。 DIV、DIV-和DIV+组中分别测量了33、90和78个IVS。 DIV组的椎体高度总增长百分比显着高于DIV和DIV+组（分别为56.6 +/- 20.3% vs. 45.6 +/- 18.0%和42.7 +/- 16.2%，P
Study Design. Retrospective radiographic study.Objective. To investigate the growth of the vertebrae around distal instrumented vertebra (DIV) in patients with early-onset scoliosis (EOS) who underwent dual growing rod (DGR) treatment.Summary of Background Data. Previous studies indicated that DGR was likely to preserve or even stimulate the spinal growth. However, report pertaining to the effect of growing rod on the growth of individual vertebral body is rare.Methods. The EOS patients treated with DGR who had at least four lengthenings and 5-year follow-up were enrolled. Spine radiographs at index surgery and final follow-up were reviewed. The height, width, and depth of vertebral body from DIV-2 to DIV+2, and the height of the adjacent intervertebral space (IVS) were measured. The percentage of growth was calculated.Results. Thirty-one patients (mean age, 6.2 +/- 2.5 years old) met the inclusion criteria, 74.2% (23/31) of whom were female. The average follow-up was 6.2 years (range, 5.0-10.4 yr). The measured vertebrae were divided into DIV group (n = 65), DIV-group (DIV-1 and DIV-2, n = 60), and DIV+ group (DIV+1 and DIV+2, n = 47). There were 33, 90, and 78 measured IVSs in DIV, DIV-, and DIV+ group, respectively. The total percentage growth of vertebral height was significantly higher in DIVgroup than that in DIV and DIV+ groups (56.6 +/- 20.3% vs. 45.6 +/- 18.0% and 42.7 +/- 16.2%, respectively, P
