Safety factors analysis for atlas-axis components screw tunnel of artificial atlanto-odontoid joint 人工寰齿关节寰枢椎部件固定钉道的安全因素分析
Objective To study the safety over the atlanto-odontoid joint of the cervical spine during oblique-pulling manipulation. 目的研究颈椎斜扳法下寰齿关节的安全性。
The imageology showed that forward atlantoaxial subluxation was verified in 16 cases, which was related with erosive osteoclasia in the atlantoaxial, atlanto-odontoid and atlanto-occipital joints. 影像学结果显示前向寰枢椎半脱位最常见,有16例,与侵蚀性骨破坏累及寰枢、寰齿、寰枢关节有关。
