The effect of the acetabular abduction by the pelvic obliqueness and its clinical significance / 医学研究生学报

Objective:This study was designed to measure the angles of the acetabular abduction when facing the different pelvic obliqueness angles.Methods:The angle of the acetabular abduction of 21 pelvis all 42 hip joints were measured with the manual devices when facing the 9 different pelvic obliqueness angles.Results:The pelvic obliqueness angle and abduction angle showed the positive linear correlation by the linear regress analysis.(r=0.999,P=0.000).The average abduction angle was 46.5?(43.8?-49.2?)when the obliqueness angle was 0?,as obliqueness angle of the pelvis increase to 10?,the abduction increase to 9.4?. Conclusion: The results provided reliable anatomical basis for total hip arthroplasty.
