目的探讨应用寰枢椎后路椎弓根螺钉固定技术治疗少儿上颈椎不稳的可行性及临床疗效。方法在气管插管全麻下对8例4~10岁的幼儿上颈椎不稳患者施行寰枢椎后路椎弓根钉棒固定。结果全组8例均获寰枢椎椎弓根螺钉固定,术后随访6~22个月,临床症状得到不同程度的改善;X线、CT复查螺钉位置良好,无松动、断钉,植骨3~6个月后均达到满意融合。结论少儿具有进行寰椎和枢椎椎弓根螺钉固定的临床可行性,可作为治疗少儿寰枢椎不稳的方法选择。
Objective To investigate the feasibility and clinical efficacy of posterior transaxial pedicle screw fixation in the treatment of cervical spine instability in children. Methods Under general anesthesia with endotracheal intubation, 8 patients with 4 ~ 10 years old children with upper cervical instability were treated with atlantoaxial posterior pedicle screw fixation. Results All 8 patients were atlantoaxial pedicle screw fixation, followed up for 6 to 22 months, the clinical symptoms were improved to varying degrees; X ray, CT review of the screw position is good, no loosening, broken nail, bone graft 3 to 6 months after reaching satisfactory fusion. Conclusion Children with atlas and pedicle screw fixation of clinical feasibility, can be used as a treatment of pediatric atlantoaxial instability method of choice.
