Abstract：
To evaluate the corrective effect of posterior hemivertebra resection and short-segment fusion surgery on pediatric patients and to assess the impact of short-segment fixation surgery on vertebral development during follow-up, a retrospective analysis was performed on 28 pediatric patients who underwent posterior hemivertebra resection surgery. The corrective effect was evaluated by comparing indicators such as segmental scoliosis Cobb angle, upper and lower compensatory curves and trunk balance at different time points. Meanwhile, the vertebral and spinal canal diameters of instrumented vertebrae and adjacent noninstrumented vertebrae were measured and compared to assess vertebral and spinal canal development. The correction rate of segmental scoliosis was 72.2%. The estimated mean vertebral volume of the instrumented vertebra was slightly lower than that of the unfused segment at the final follow-up, but the difference was not statistically significant. The growth rate of the spinal canal during follow-up was much smaller than that of the vertebral body. In summary, internal fixation at a young age shows no significant inhibitory effects on spinal development within the fusion segment. Posterior hemivertebra resection and short-segment fusion surgery are safe and effective.
摘要：
评价后路半椎体切除及短节段融合术对患儿的矫正效果，并评估短节段内固定手术对术后椎体发育的影响。我们对28例接受后路半椎体切除手术的儿科患者进行了回顾性分析.通过比较节段性脊柱侧凸Cobb角、不同时间点的上、下代偿曲线和躯干平衡。同时,测量并比较有器械椎骨和相邻无器械椎骨的椎骨和椎管直径，以评估椎骨和椎管的发育。节段性脊柱侧凸的矫正率为72.2%。在最后一次随访时，器械椎骨的估计平均椎体体积略低于未融合节段的椎体体积，但差异无统计学意义。随访期间椎管的生长速率远小于椎体的生长速率。总之,年轻时的内固定对融合段内的脊柱发育没有明显的抑制作用。后路半椎体切除和短节段融合手术是安全有效的。
