管道疏通法在下颈椎经皮椎弓根螺钉内固定术中的应用

目的比较椎板部分切除置钉法、Abumi法、管道疏通法在颈椎(C3～7)经皮椎弓根螺钉内固定术中的应用。方法选择60例需经皮椎弓根螺钉固定术治疗的下颈椎疾病患者,根据其手术方式分成3组:椎板部分切除置钉组(A组)、Abumi组(B组)、管道疏通组(C组),各置入椎弓根螺钉80枚。出院前评估置钉满意率。结果 A组置钉评价为:优54枚,良13枚,差13枚,满意率为83.8%;B组置钉评价为:优56枚,良14枚,差10枚,满意率87.5%;C组置钉评价为:优72枚,良5枚,差3枚,满意率96.3%。C组患者的置钉满意率明显优于A、B组,3组之间差异有统计学意义。结论管道疏通法在经颈后路椎弓根螺钉内固定术中优势明显。

Application of dredging pipe method in percutanous pedicle screw fixation of lower cervical vertebrae

Objective To compare the application of partial laminectomy with pedicle screw placement,Abumi method and dredging pipe method in the percutanous pedicle screw fixation of the cervical vertebrae C3-7.Methods 60 patients with lower cervical spine disease who need percutanous pedicle screw fixation were selected and divided into 3 groups according to their operation method:partial laminectomy with pedicle screw placement group(group A),Abumi method group(group B) and dredging pipe method group(group C),with 80 pedicle screws placed in each group.Satisfaction rate of screw placement was evaluated before discharge from hospital.Results Evaluation of screw placement of group A:excellent in 54 screws,good in 13 screws and poor in 13 screws,with the satisfaction rate of 83.8%.Evaluation of group B:excellent in 56 screws,good in 14 screws and poor in 10 screws,with the satisfaction rate of 87.5%.Evaluation of group C:excellent in 72 screws,good in 5 screws and poor in 3 screws,with the satisfaction rate of 96.3%.The satisfaction rate of patients in group C was markedly superior to those in group A and B,and the difference among the 3 groups showed statistically significance.Conclusion Dredging pipe method have obvious advantages in pedicle screw fixation through posterior approach to cervical spine.
