| 摘 要： | 目的利用多层螺旋CT容积再现技术测量国人肱骨近端三维解剖结构核心参数,比较性别和侧别的差异,为研制适用于国人解剖结构特点的新一代肱骨近端假体提供参考。方法征集重庆地区正常成年志愿者100例,男59例,女41例;年龄21～57岁,平均40.4岁。经多层螺旋CT扫描双侧肩峰至肱骨滑车末端后,将信息传送到LEONARDO工作站。利用容积再现技术测量前后扭转角(retroversion angle,RA)、股骨头倾斜角(neck-shaft angle,NSA)、向内的偏心距(medial offset,MO)和向后的偏心距(posterior offset,PO)。将测量结果进行左右侧、男女性别间比较,并分析参数间相关性。结果 100例200侧肩关节RA为(19.9±10.6)°,NSA为(134.7±3.8)°,MO为(4.0±1.1)mm,PO为(2.6±1.3)mm。RA及MO左、右侧比较,差异有统计学意义(P<0.05);NSA及PO左、右侧比较,差异无统计学意义(P>0.05)。男性双侧肩关节RA及PO均大于女性(P<0.05),NSA及MO均相似(P>0.05)。PO和RA成正相关(r=0.617,P=0.000),MO和NSA无相关性(r=—0.124,P=0.081)。结论 RA及MO存在侧别差异,不能用对侧测量值作为模板;RA和PO存在性别差异。假体设计和肱骨近端重建时,需注意考虑以上因素。

| Abstract: | Objective To investigate the key parameters of three-dimensional anatomy of the proximal humerus and compare the differences between male and female,and between left and right sides in Chinese by volume rendering technique with multi-slice spiral CT(MSCT) so as to provide a reference for a new prosthesis of the proximal humerus which can adjust to the anatomical characteristics of Chinese.Methods A total of 100 healthy volunteers were collected from Chongqing of China,including 59 males and 41 females with ... |
