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.
为了评估后路半椎体切除短节段融合术对儿童患者的矫正效果，并评估短节段固定术对随访期间椎体发育的影响，对 28 例接受后路半椎体切除术的儿童患者进行了回顾性分析。通过比较不同时间点的节段性脊柱侧凸 Cobb 角、上下代偿性曲线和躯干平衡等指标来评估矫正效果。同时，测量并比较了置钉椎体和相邻非置钉椎体的椎体和椎管直径，以评估椎体和椎管的发育情况。节段性脊柱侧凸的矫正率为 72.2%。在最终随访时，置钉椎体的估计平均椎体体积略低于未融合节段，但差异无统计学意义。随访期间椎管的生长速度明显小于椎体。总之，在融合节段内，早期内固定对脊柱发育没有明显的抑制作用。后路半椎体切除短节段融合术是一种安全有效的方法。
