Thoracolumbar fractures in children are relatively uncommon and should be regarded as a separate entity from those in adults. While percutaneous pedicle fixation has emerged as an effective alternative to open fixation in adults with unstable thoracolumbar fractures, this technique is rarely applied in children. We report a 6-year-old girl with an L3 chance fracture, which was treated via short-segment percutaneous pedicle fixation. We also discussed the technical challenges and caveats of this surgical technique in young children. While potentially more challenging, percutaneous pedicle fixation is feasible in young children with thoracolumbar fractures. Specific differences between the developing and mature spine in regard to anatomical and biomechanical characteristics, including ligamentous laxity and intrinsic elasticity, should be taken into consideration. Future studies are needed to compare outcomes of minimally invasive spinal techniques to open surgery in children.

儿童胸腰椎骨折相对少见，应被视为与成人分开的实体。尽管在不稳定的胸腰椎骨折的成年人中，经皮椎弓根内固定已成为开放固定的有效替代方法，但这种技术很少用于儿童。我们报告了一个6岁的L3偶然骨折的女孩，这是通过短节段经皮椎弓根固定术治疗的。我们还讨论了这种手术技术在幼儿中的技术挑战和注意事项。尽管可能更具挑战性，但经皮椎弓根固定术在胸腰椎骨折的幼儿中是可行的。发育中的脊椎和成熟的脊椎在解剖学和生物力学特征方面的特定差异，包括韧带松弛和固有弹性，应该考虑在内。需要进行进一步的研究，以比较微创脊柱技术对儿童开放手术的效果。
