经寰枢椎椎弓根钉棒(板)内固定治疗急性创伤性寰枢椎不稳

目的探讨经寰枢椎椎弓根钉棒(板)内固定治疗急性创伤性寰枢椎不稳的临床效果及其安全性。方法对8例急性创伤性寰枢椎不稳的患者施行经椎弓根钉棒(板)内固定 植骨融合术,观察术后近期疗效及并发症情况。结果术中未发生血管、神经等重要组织结构的损伤,经6~20个月的随访,术后症状均得到不同程度的改善,无内固定物松动及断裂,所有植骨均达骨性融合。结论经寰枢椎椎弓根钉棒(板)内固定是治疗寰枢椎不稳的一种可靠的治疗方法,有利于上颈椎稳定性重建及脊髓神经功能恢复。

C1,2 pedicle screw internal fixation for traumatic atlantoaxial instability

Objective To evaluate the clinical effect and safety of C_(1,2) pedicle screw-rods/plates internal fixation for traumatic atlantoaxial instability.Methods Eight patients with traumatic atlantoaxial instability were treated by C_(1,2) pedicle screw-rods/plates internal fixation and bone graft fusion.The immediate outcome and complications were observed.Results There was no vascular or neural injury found.The patients were followed up from 6 to 20 months.The clinical symptom was improved in some extent after operation.No looseness or breakage of screw occurred.Bony fusion was achieved in all cases.Conclusions C_(1,2) pedicle screw-rods/plates internal fixation is a reliable method for atlantoaxial instability,which can reestablish the upper cervical vertebrae stability and help to recover the spinal cord and nerve function.
