【摘要】 目的 :测量国人肱骨头相关解剖数据 ,为设计适合中国人的肱骨头假体提供参考值。方法 :10 0根成对防腐肱骨 (男 2 8对 ,女 2 2对 ) ,用CT软件测量头心 -干轴距、头干角、头 -结节高度差、头半径、关节面张角等共 13项参数。结果 :所得数据行统计学处理 ,得出各参数分布规律及其间的相关性 ,性别间比较有显著差异 ,而左右间差异不显著 ,除头干角比西方人稍大外 ,其余参数均较西方人小 ,差异有非常显著性意义 (P <0 .0 1)。结论 :有必要设计符合国人肱骨解剖特点的假体。更多还原

【Abstract】 Objective: To measure Chinese humeral head for the design of humeral prosthesis component by CT osteometry. Methods: Thirteen parameters of 100 embalmed cadaveric humeri(50 pairs: 28 males and 22 females) were measured exactly by image analytic computer software that included offset, head-shaft angle, head to tuberosity height, curvature radius, articular surface arc, et al. Results: The principles of the distribution, correlation and confidence in all parameters were found. Profound differences were observed between male and female, but not between right and left. All the data were statistically smaller in the Chinese than that of the foreigner except head-shaft angle. Conclusion: It is necessary to design the humeral components fitting the feature of the humeri of the Chinese.更多还原
