| 目的 探讨人工寰齿关节寰枢椎部件固定螺钉通道的安全性和可行性，为经口咽入路置换人工寰齿关节提供理论上的依据。方法 在10具正常成年人尸体寰枢关节湿性标本上行人工寰齿关节置换术，测量寰椎部件上下位固定螺钉的长度和外倾角，测量枢椎部件固定螺钉的长度，测量枢椎部件固定螺钉的外倾角和下倾角等。结果 寰椎部件上下位固定螺钉的长度（Ls、Li）分别为19.3 mm±2.2 mm和20.4 mm±3.5 mm；寰椎部件上下位螺钉外倾角（α，β） 分别为5.2°±2.5°和14.4°±4.2°；枢椎部件固定螺钉的长度（S）是24.2 mm±4.9 mm；枢椎部件固定螺钉的外倾角度（θ）是24.8°±4.3°，枢椎部件固定螺钉的下倾角度（δ）是19.2°±4.5°。结论 固定人工寰齿关节寰枢椎部件的螺钉通道不仅具有可行性，而且可以避开横突孔、椎动脉沟及椎管等重要解剖结构。 |

| Objective To investigate feasibility and safety for atlas-axis components screw tunnel of artificial atlanto-odontoid joint. To provide theoretic evidence for transoral approach (TOA) in dealing with the placement of artificial atlanto-odontoid joint. Methods The relative anatomic parameters of 10 sets of artificial atlanto-odontoid joint arthroplasty on adults' bony specimens were measured with an digital caliper and a goniometer, including the length and extraversion angle of superior and inferior screws of atlas components, the length of axis components screw tunnel, the extraversion angle and downslope angle of axis components screw tunnel and so on. Results The length of superior and inferior screws of atlas components (Ls,Li) was 19.3 mm ± 2.2 mm and 20.4 mm ± 3.5 mm, respectively. The extraversion angle of superior and inferior atlas components screw tunnel (α, β) was 5.2°± 2.5°and 14.4°± 4.2°, respectively. The length of superior and inferior screws of axis components (S) was 24.2mm ± 4.9 mm, the extraversion angle of axis components screw tunnel (θ) was 24.8°± 4.3°, the downslope angle of axis components screw tunnel (δ)was 19.2°± 4.5°. Conclusion It is feasibility for atlas-axis components screw tunnel of artificial atlanto-odontoid joint, and it provides comparatively large safety space, and it can get out of the way of some important anatomy structures, such as transverse foramen, groove for vertebral artery, vertebral canal and so on. |
