摘要:

背景:全髋置换中良好的髋臼假体方位对于手术的成功起到了至关重要的作用。传统定位工具或精确度欠佳、或太过繁琐,限制了其应用。

目的:对比陀螺定位仪与传统定位技术在全髋置换髋臼杯定位中的优劣。
方法:应用外侧入路,在同一个塑料髋部模型上由不同经验年限的医生利用传统方法进行了100次髋臼杯定位(每人20次40°外展和15°前倾);再利用陀螺定位仪分别进行了60次相同角度的定位,记录实测角度与事先设定角度的误差。
结果与结论:与传统技术相比,使用螺仪定位仪测量的外展角和前倾角误差明显下降。提示陀螺定位仪能使全髋置换中髋臼杯的定位更加精确。

Abstract:

 BACKGROUND: Good position of acetabular prosthesis during total hip replacement plays a key role in success of the operation. Traditional location tool has poor accuracy, is too complicated, and limits its application.

OBJECTIVE: To compare the advantages and disadvantages of gyroscope with the traditional technique in acetabular component orientation in total hip arthroplasty.
METHODS: Using lateral approach, physicians with different experiences used traditional technique to locate acetabular cup 100 times (20 times in each person; 40° abduction and 15° anteversion), and then used gyroscope to locate 60 times at the same angle in the same plastic hip model. The error between the planed and measured values was recorded.

RESULTS AND CONCLUSION: Compared to the traditional technique, the error of the abduction and anteversion decreased obviously. These indicated that the gyroscope can make the orientation of acetabular component more precise in total hip arthroplasty.
