1、XX大学毕业论文尺骨变异在健康人群中的分布2014年6月25日尺骨变异在健康人群中的分布作者：刘杰，刘名，何磊，孙广超【摘要】［F1的］探讨尺骨变异与性别和年龄之间的关系。［方法］随机选取健康志愿者200名，均为右利手。入选标准为既往无急、慢性腕关节疾病及腕部和前臂骨折病史。其屮男117名，女83名；年龄18〜84岁，平均41.7±16.4岁。对入选者拍摄标准腕关节正位X线片，测量取得309个尺骨变界数值，按照性别、年龄、左右侧腕分组后分别进行统计学分析。［结果］在全体健康者屮，尺骨变异发生率为：正向变异48.9%,屮性变异39.8%
2、,负向变异11.3%。在男性健康者中,三种尺骨变异的发生率为:正向变异50.0%,中性变异39.2%,负向变界10.8%；女性健康者中，三种尺骨变异的发生率为：正向变异47.4%,中性变杲40.6%，负向变杲12.0%。结果显示随着年龄的增长，尺骨变杲出现正向和负向变界的比率增高，而屮性尺骨变异的比率降低。这种变化规律在男女性别之间无明显差异。左腕尺骨变异发生率为：正向变异49.7%,屮性变异39.3%,负向变异11.0%o右腕的正向变异为48.2%,中性变异为40.6%,负向变异为11.5%。两侧尺骨变异的分布无明显区别。［结论］（
3、1）在健康人群屮，主要为正向和屮性尺骨变杲，负向尺骨变界较少。（2）随着年龄的增长，尺骨变异发生动态变化。（3）在健康的男女性人群屮，尺骨变异性的分布无明显差异。（4）在健康人群
