文题释义:
寰枢椎脱位:可分为可复性、难复性和不可复性脱位3种类型,其可导致C1-2水平脊髓压迫而造成神经功能障碍症状,多需要进行手术治疗,以后路钉棒固定融合为应用最广泛的手术方式。
寰枢椎后路钉棒固定融合:该技术分别在寰椎、枢椎独立置钉,不仅具有螺钉进钉角度小、适用人群广、固定强度高等优势,而且术中能够通过钉棒提拉以复位寰枢椎,被认为是寰枢椎新的金标准固定术式,再联合后路植骨,使得寰枢椎最终获得骨性融合而达到稳定状态,提高寰枢椎脱位的治疗效果、安全性、适用性和便利性。
 
摘要
背景:后路植骨融合钉棒内固定是治疗寰枢椎脱位的常用手术方法,寰枢椎间的骨性融合是手术治疗的最终目的。目前,临床中寰枢椎后路手术可应用多种植骨材料及置钉方式,而术后患者获得植骨融合的时间也多有不同。
目的:分析寰枢椎脱位后路不同植骨材料及钉棒内固定方式对植骨后融合时间的影响。
方法:回顾性分析2009年8月至2015年12月286例采用寰枢椎后路植骨融合钉棒内固定并获得寰枢椎间植骨融合的可复性寰枢椎脱位患者。寰椎固定采用完全经椎弓根螺钉,枢椎固定采用椎弓根螺钉或椎板螺钉,后路植骨材料采用自体骨松质骨粒或异体骨松质骨粒。
结果与结论:术后获得植骨融合时间3-24个月,C1双侧椎弓根螺钉+C2双侧椎弓根螺钉、 C1双侧椎弓根螺钉+C2双侧椎板螺钉、C1双侧椎弓螺钉+C2一侧椎弓根螺钉+C2对侧椎板螺钉3种内固定方式对术后植骨融合时间的影响差异无显著性意义(F=2.134,P=0.120),自体骨松质骨粒和异体骨松质骨粒2种植骨材料术后植骨融合时间差异有显著性意义(F=83.611,P=0.000),内固定方式和植骨材料间无交互作用(F =1.036P=0.356)。说明不同寰枢椎后路钉棒内固定方式均可提供稳定可靠的植骨融合环境,自体骨材料植骨更加有利于术后获得植骨融合,缩短融合时间。

Abstract:

BACKGROUND: Posterior screw-rod fixation is a popularized method in the treatment of atlantoaxial dislocation to eventually achieve intervertebral fusion. There are various graft materials and fixation methods that show different fusion time.

OBJECTIVE: To analyze the effect of different graft materials and internal fixation methods on the fusion time in the posterior atlantoaxial dislocation surgery.
METHODS: 286 patients with reducible atlantoaxial dislocation undergoing C1-2 posterior screw-rod fixation and obtaining successful intervertebral fusion from August 2009 to December 2015 were analyzed retrospectively. Complete pedicle screw was used for C1 screw fixation, and pedicle or laminar screws were for C2 screw fixation. The graft materials included autogenous or allogeneic grains of cancellous bone.
RESULTS AND CONCLUSION: The fusion time ranged from 3 to 24 months. The fusion time did not differ significantly among fixation methods (F=2.134, P=0.120). There was significant difference in the fusion time between graft materials (F=83.611, P=0.000). Besides, there was no correlation between internal fixation methods and graft materials (F=1.036, P=0.356). These results suggest that different C1-2 posterior internal fixation methods can provide stable and reliable environment for bone fusion, and autogenous bone is more beneficial for intervertebral fusion and shortens fusion time.
