摘　　要：目的:探讨在全髋关节置换术中使用液晶数字显示角度仪控制前倾角的应用价值。方法:回顾分析自2018年1月至2019年12月83例行初次全髋关节置换术的患者,其中男28例,女55例;年龄42~81(70.4±7.9)岁。股骨颈骨折63例,股骨头缺血性坏死20例。所有患者术中使用液晶数显角度仪控制髋臼杯假体的前倾角,术后采用CT扫描,测量髋臼杯的前倾角,两者进行比较,了解使用液晶数显角度仪的准确性。结果:术后CT测量提示患者的髋臼前倾角均位于Lewinnek提倡的安全区内,术中使用液晶数显角度仪测量髋臼杯的前倾角度中位数为14.20°(12.80~15.40)°,术后CT扫描测量的髋臼杯的前倾角中位数为14.20°(13.40~15.50)°,两者比较差异无统计学意义(Z=-1.725,P=0.085)。结论:应用液晶数显角仪器对术中控制髋臼杯的前倾角是一种准确可靠的方法,具有良好的辅助参考价值。Objective:To investigate the application value of liquid crystal digital display goniometer in total hip arthroplasty.Methods:From January 2018 to December 2019,83 patients underwent primary total hip arthroplasty,including 28 males and 55 females,aged 42 to 81(70.4±7.9)years.There were 63 cases of femoral neck fracture and 20 cases of avascular necrosis of femoral head.All patients used liquid crystal digital goniometer to control the anteversion of acetabular cup prosthesis during operation,and CT scanning was used to measure the anteversion of acetabular cup after operation.The two methods were compared to understand the accuracy of using liquid crystal digital goniometer.Results:Postoperative CT measurement showed that the acetabular anteversion of all patients was in the safe area advocated by Lewinnek.The anteversion angle of acetabular cup measured by liquid crystal digital goniometer was 14.20(12.80 to 15.40)°,and the anteversion angle of acetabular cup measured by postoperative CT scan was 14.20(13.40 to 15.50)°.There was no significant difference between the two(Z=-1.725,P=0.085).Conclusion:It is an accurate and reliable method to control the anteversion of acetabular cup with liquid crystal digital display angle instrument,which has a good auxiliary reference value.
