摘要:


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,临床上多需要进行手术治疗,后路钉棒固定融合术是最常用的手术方式。

寰枢椎板间融合器:与寰枢椎侧块关节融合器不同,其直接固定在寰椎后弓与枢椎椎板骨面上,是一种新型融合器,此融合器可配合广泛使用的后路钉棒内固定手术,置入简便,增加植骨与寰椎后弓及枢椎椎板骨面的接触应力,促进骨性融合。

背景:寰枢椎融合器一直以侧块关节融合器为研究热点,但其置入操作风险过大,目前临床上一直缺乏可广泛应用的寰枢椎融合器。

目的探究成人后路寰枢椎板间融合器的CT影像解剖学可行性并给出初步设计。

方法100例成人(50例,女50)寰枢椎CT三维成像进行测量,测量指标包括寰椎单侧后弓长度、寰椎后弓厚度、枢椎单侧椎板长度、枢椎椎板厚度、寰椎后弓上缘至枢椎椎板下缘距离,分析寰枢椎后方部分结构的CT测量数据并设计寰枢椎板间融合器。

结果与结论男、女性的寰椎单侧后弓长度分别为(23.41±1.48) mm(22.23±1.25) mm,寰椎后弓厚度分别为(6.00±0.96) mm(5.28±0.78) mm,枢椎单侧椎板长度分别为(18.54±2.23 )mm(17.31±0.91) mm,枢椎椎板厚度分别为(5.12±1.31) mm(4.98±1.26) mm,寰椎后弓上缘至枢椎椎板下缘距离分别为(32.63±2.76) mm(31.39±4.04) mm不同性别的双侧测量数据差异无显著性意义(P > 0.05);男性的寰椎单侧后弓长度、寰椎后弓厚度、枢椎单侧椎板长度大于女性,差异有显著性意义(P < 0.05);男性与女性的枢椎椎板厚度、椎后弓上缘至枢椎椎板下缘距离差异无显著性意义(P > 0.05)寰枢椎后方部分结构的CT测量结果提示寰枢椎板间融合器是可行的;寰枢椎板间融合器初步设计成功,并获得国家专利;提示寰枢椎板间融合器具有应用可行性,可用于寰枢椎后路钉棒固定融合过程中,提升寰枢椎间的植骨融合率。

Abstract:

BACKGROUND: Atlantoaxial lateral mass joint fusion cage has always been a focus of research, but its implant operation is too risky. At present, there is no widely used atlantoaxial fusion cage.

OBJECTIVE: To investigate the anatomical feasibility of CT image and preliminary design of posterior atlantoaxial interlaminar fusion cage in adults.

METHODS: Measurement of atlantoaxial three-dimensional CT of 100 adult cases (50 males and 50 females) was performed, including C1 unilateral posterior arch length, C1 posterior arch width, C2 unilateral lamin length, C2 lamina thickness and the distance of C1 posterior arch higher edge to C2 lamin lower edge. CT measurement data of posterior part of atlantoaxial structure were analyzed, and atlantoaxial interlaminar fusion cage was designed.

RESULTS AND CONCLUSION: (1) The C1 unilateral posterior arch length of man and woman was (23.41±1.48) mm and (22.23±1.25) mm respectively, and the C1 posterior arch width was (6.00±0.96) mm and (5.28±0.78) mm respectively, and the C2 unilateral lamin length was (18.54±2.23) mm and (17.31±0.91) mm respectively, and the C2 lamina thickness was (5.12±1.31) mm and (4.98±1.26) mm, respectively. The distance of C1 posterior arch higher edge to C2 lamin lower edge was (32.63±2.76) mm and (31.39±4.04) mm, respectively. (2) There were no statistically significant differences in the bilateral measurement data of different genders (P > 0.05). The C1 unilateral posterior arch length, C1 posterior arch width and C2 unilateral lamin length in men were larger than those in women, and the differences were statistically significant (P < 0.05). There were no statistically significant differences in the C2 lamina thickness and the distance of C1 posterior arch higher edge to C2 lamin lower edge of different genders (P > 0.05). (3) CT measurement data suggested that atlantoaxial interlaminar fusion cage is feasible. (4) Preliminary design of atlantoaxial interlaminar fusion cage was successful, and obtained the national patent. (5) It is suggested that atlantoaxial interlaminar fusion cage has application feasibility and can be used in posterior atlantoaxial screw-rod fixation and fusion to improve the fusion rate of bone graft.
