[Abstract]:Objective to investigate the effect of pelvic adductive outreaching motion on acetabular abduction angle and to improve the accuracy of acetabular prosthesis abduction angle placement by posterolateral approach in THA. Methods 1 Experimental method 1.1 measured 15 normal adult pelvic specimens, including 8 male specimens and 7 female specimens (30 hips). The pelvic specimens were sagittal axis as rotation axis and were rotated at different angles. The degree of acetabular abduction was measured. The data were recorded and sorted, and the linear correlation between abduction angle and pelvis rotation angle was analyzed by SPSS13.0 statistical software. Statistical analysis of male and female pelvic specimens measured abduction angle at the same pelvic rotation angle is statistically different. 1.2 Imaging measurement of normal people in lateral position along the sagittal axis of the pelvis rotation angle of 60 volunteers to take lateral position. The pelvis positive film was taken with the bedside Dr, and the metal horizontal line and vertical line were found and placed on the relative receiver with the lead vertical line, which was used as the reference standard when measuring the angle, and the image was processed by DICOM3.0. The angle between the teardrop line of the pelvis and the vertical line was measured and the relevant data were analyzed statistically. 2 all the measured data were expressed as mean 鹵standard deviation (x 鹵s). SPSS13.0 (SPSS, USA) software was used to process and analyze the data. The acetabular abduction angle and the pelvic rotation angle along the sagittal axis were analyzed. T-test analysis of male and female acetabular abduction angle at the same pelvis rotation angle was carried out. T test analysis of the rotation angle of male and female pelvis around sagittal axis was carried out. The test level was 0. 05 on both sides. Result 1. The acetabular abduction angle was linearly correlated with the degree of rotation of the pelvis along the sagittal axis, and the regression equation was YJ 47.144 0.942 x.2. There was no significant difference in acetabular abduction angle between male and female at the same pelvic rotation angle (p > 0.05). 3. The average abduction of pelvis was 5.47 擄in lateral position. There was no significant difference in the angle of pelvic adduction and abduction between male and female in lateral position (p > 0.05). Conclusion 1. Pelvic adduction or extravasation sensitivities affect acetabular abduction angle changes. Attention should be paid to limiting pelvic adductive abduction movement during hip arthroplasty through posterolateral approach, and proper adjustment of posture should be paid attention to before and during operation. 2. The influence of sex factors on the abduction angle of acetabular prosthesis can be ignored during hip arthroplasty via posterolateral approach.
