CT三维重建下髋臼形态的测量及其意义

目的:利用髋臼CT三维重建图像对中国人髋臼形态进行相关测量,为髋关节疾病的预防和治疗提供相应的依据.方法:对96例(192侧)成年髋关节CT扫描进行三维重建,在重建图像上测量髋臼指数(AA)、CE角、ACE角、前倾角(AVA)、外展角(ABA)和髋臼上下径(SID)参数.结果:总AA为(8.78±5.34)°,其中男性...

Measurement of acetabular morphology under three-dimensional reconstruction of CT and its significance

Objective To measure the acetabular morphology of Chinese on CT three-dimensional(3D) reconstruction image,and provide the evidence on the prevention and treatment of hip diseases.Methods 96 cases(192 sides) of adult hip CT scans were reconstructed,the acetabular index(AA),center-edge(CE),ACE angle,anteversion angle(AVA),abduction angle(ABA),and vertical diameter(SID) were measured.Results The total acetabular index was(8.78 ± 5.34) °,of which male was(7.84 ± 5.55) °and female was(9.60 ± 5.06)°.The total CE was(33.59 ± 5.91) °,of which male was(34.55 ± 6.03) ° and female was(32.78 ± 5.70) °.The total ACE angle was(29.01 ± 5.65) °,of which male was(28.02 ± 5.94) °and female was(29.80 ± 5.30)°.The total AVA was(20.92 ± 5.55)°,of which male was(20.48 ± 5.08)°and female was(21.25 ± 5.89)°.The total ABA was(51.27 ± 4.16) °,of which male was(51.71 ± 4.37)°and female was(50.89 ± 3.96)°.The total SID was(53.79 ± 3.92) mm,of which male was(56.55 ± 2.64) mm and female was(51.46 ± 3.25) mm.Of the above data,there were statistical differences in the acetabular index,CE angle,ACE angle and acetabular diameter between men and women(P<0.05),Chinese and foreigners(P<0.05).While there was no statistical difference between the left and right sides(P>0.05).Conclusion There are differences in acetabular morphology between men and women,Chinese and foreigners.Compared with simply using overseas data,it is better to study morphological parameters of native acetabulaum to instruct the preoperative preparation and operation of national total hip arthroplasty surgery.And it is meaningful to design national parameters.
