OBJECTIVE: To evaluate the clinical outcomes of atlantoaxial pedicle screw system in the treatment of atlantoaxial instability from odontoid fracture.

目的：分析椎弓根钉棒系统治疗齿状突骨折引起寰枢椎不稳的临床疗效。

Apofix technigue was used to treat 17 cases of fresh odontoid fracture and 1 case of old odontoid fracutre.

采用Apofix椎板钩治疗新鲜齿状突骨折17例，陈旧性骨折1例，均伴有寰枢椎不稳，并有不同程度的枕颈部疼痛，活动受限。

Methods: Injured patients of cervical spine was cayyied on X-ray inspection.,then according to the result of ADI and LADS ,next to CT or MRI inspection ,and that was to guide clinical diagonosis and treatment.To observe atlanto-dental interval (anterior arch of atlas posterior border to odontoid process anterior border) and odontoid process caster(included angle between axis of ordinate of odontoid process and axis of ordinate of odontoid vertebra) on the X-ray lateral projection.

对有颈部外伤史的病人常规行X线检查，然后根据寰齿间距和齿突侧块间隙的结果，行下一步CT检查或者MRI检查，指导临床治疗方法的选择。X线侧位片观察寰齿前间隙(为寰椎前弓后缘与齿突前缘距离)，齿状突后倾角(齿突纵轴与枢椎体纵轴的夹角)；开口正位片上测定齿突侧块间隙。

Objective To investigate a new method for axial pedicle screw placement based on virtual-reality technology.

目的 探索以虚拟现实技术为基础的枢椎椎弓根螺钉置入方法。

Objective To evaluate the clinical outcomes of using pedicle screw fixation in the treatment of hangmans fracture.

小摘要：目的评介椎弓根螺钉内固定治疗枢椎椎弓骨折的临床应用价值。

The outcomes of diaplasis and fixation by using pedicle screw fixation in treatment on acture hangmans fracture were satisfaction, and this clinical technique can promot functional recovery of spinal cord, decrease the rate of infection and less affect the function of uper cervical spine.

椎弓根螺钉内固定治疗早期枢椎椎弓骨折，复位固定满意，促进脊髓功能的恢复，且较少影响上颈椎功能。

Objective: To evaluate the biomechanical stability of C1-C2 pedicle screws fixation technique for atlantoaxial instability.

目的：评价寰枢椎后路椎弓根螺钉钢板固定的生物力学稳定性。

Objective: To evaluate safety and reliability with freehand technique of posterior lateral mass screw implantation in the treatment of atlantoaxial instability.

目的：评价寰枢椎后路侧块和椎弓根螺钉徒手置入技术的安全性和可靠性。

Fusion can provide stabilization for atlanto-axial joint, but it restricts the movement between atlas and axis and induces degeneration and instablility of unfused cervical spine.

本研究旨在开发一种人工寰齿关节，临床应用它来治疗寰枢椎脱位与不稳，以达到既恢复寰枢关节的稳定性又保留其运动功能的目的。

Methods the angles from the body surface of yamen (gv 15) to the joint line between the level opposide atlas and axis, and the joint line between body surface of yamen point and posterior margin of the great occipital foramen, upper margin of arcus posterior atlantis were measured respectively in 1120 cases of t1 weighted image of median sigittal position with mri, and the data were processed by computer.

取1120例mri正中矢状位t1加权像，分别测量体表哑门穴至水平相对寰、枢椎椎间的连线与体表哑门穴至枕骨大孔后缘连线、寰椎后弓上缘连线所夹的角度，并由计算机进行数据处理。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
