中文摘要:
目的：测量C7椎板的解剖学参数，探讨C7后路椎板螺钉固定的可行性。
方法：用游标卡尺和量角器测量22具成人C7标本与椎板螺钉进钉技术相关的解剖学数据，指标包括椎板上、中、下部分的厚度(分别为T1、T2、T3),椎板高度(H),进钉点至椎弓根内侧壁及侧块外侧壁的距离(分别为L1、L2),椎板轴线与矢状面的夹角(α).
结果：椎板上部厚度(T1)平均为(4.30±0.27) mm;中部厚度(T2)平均为(5.32±0.27) mm,27%(6例)小于4.50 mm;下部厚度(T3)平均为(4.78±0.26) mm;椎板中下部厚度均大于4.50 mm;椎板高度(H)平均为(14.83±0.26) mm;进钉点至椎弓根内侧壁的距离(L1)平均为(26.99±0.48) mm;最长钉道长度(L2)平均(41.60±1.10) mm;椎板与矢状面夹角(α)平均(49.3±1.1)°。
结论：C7后路椎板螺钉固定是可行的，适用于多数患者(73%).与C7椎弓根螺钉技术相比，椎板螺钉技术更简单，神经血管损伤的可能性更低。 |

ABSTRACT
Objective: To measure anatomic data of laminar of C7 and evaluate the possibility of the placement of C7 laminar screw.
Methods: Twenty-two specimens of C7 were measured with an vernier caliper and a goniomete and finded out the anatomic data for prominent vertebra laminar screw placement. The indicators included the thickness of the superior,median and inferior part of C7 laminar(T1,T2,T3),the height of the laminar(H),the distance of the anchor point to the medial wall of C7 pedicle and the lateral wall of the lateral mass(L2,L2) and the angle between the axis of C7 lamina and sagittal plane(α).
Results: The mean thickness of superior part of C7 lamina(T1) was(4.30±0.27) mm,(5.32±0.27) mm in median part(T2) with 27%(6 cases)of specimens thickness less than 4.50 mm and(4.78±0.26) mm in inferior part(T7). Both median part and inferior part were thicker than 4.50 mm. The mean height of C7 laminar(H) was (14.83±0.26) mm. The distance from the laminar anchor point to the medial wall of C7 pedicle(L1) and the lateral wall of the lateral mass(L7) was (26.99±0.48) mm and (41.60±1.10) mm respectively. The mean angle between the axis of C7 laminar and sagittal plane(α) was (49.3±1.1)°。
Conclusion: It is feasible to place screw in C7 laminar and this technique can be applied in 73% of Chinese. Compared with C7 pedicle screw technique,this technique is simple with little risk to the nerve and vascular structures. |
