【摘要】 目的比较术中直观测量与术后不同测量方法测量髋臼前倾角的差距。方法术中使用双臂不锈钢角度尺直观测量髋臼假体前倾角度数,术后在髋关节X线片上使用Mclaren、Ackland和Pradhan等提出的测量方法,使用相同的定义和参考平面分别测量计算术后髋臼假体前倾角度数。结果术中直观测量和术后用Mclaren、Ackland和Pradhan等提出的3种不同方法测量的髋臼假体前倾角度数的平均误差和标准差分别为(9.09±1.66)°、(9.33±1.35)°和(5.64±1.26)°,差异有统计学意义(P<0.01),但术中直观测量和术后用Pradhan方法测量的髋臼假体前倾角度数误差最小。结论术中直观测量和术后用Pradhan法测量的髋臼假体前倾角度数差距最小。更多还原

【Abstract】 Objective To compare the measurement differences of front rake of acetabular prosthesis between intraoperative direct measurement and different measurement methods after operation in patients with total hip arthroplasty( THA). Methods An intuitionistic measurement of the angle of the acetabular prosthesis was performed by a double arm stainless steel angle ruler during the operation,and the angle of the acetabular prosthesis after operation was detected on X-ray of hip joint according to the methods proposed by Mclaren,Ackland and Pradhan. Degree of the angle of acetabular prosthesis after operation was detected by the same definition and reference. Results The angles of acetabular prosthesis detected between intraoperative direct measurement and methods proposed by Mclaren,Ackland and Pradhan were( 9. 09 ± 1. 66) °,( 9. 33 ± 1. 35) ° and( 5. 64 ± 1. 26) °,and there were significant differences( P < 0. 01). Deviation of angle of acetabular prosthesis detected between intraoperative direct measurement and method proposed by Pradhan was the lowest. Conclusion Deviation of angle of acetabular prosthesis is the lowest between intraoperative direct measurement and method proposed by Pradhan.更多还原
