摘　　要：目的探讨中国汉族成人肱骨近端CR片的特征随年龄变化的规律,以推断年龄。方法 210例中国汉族成人肩关节CR片,其中男性124例,年龄范围18~83周岁,女性86例,年龄范围18~60周岁,选取与年龄变化关系密切的肱骨骨髓腔高度、肱骨近端骨骺骨小梁变化、肱骨大结节内骨小梁变化、锁骨骨髓腔肩峰侧骨小梁变化4项指标,观察不同年龄各指标的变化进行统计分析。结果四项指标均是影响年龄变化的重要因素。肱骨近端骨骺骨小梁变化、锁骨骨髓腔肩峰侧骨小梁变化对年龄的预测影响较大,肱骨骨髓腔高度、肱骨大结节内骨小梁变化稍小。利用以上指标建立的回归方程能很好的反映成人肱骨的增龄性变化,预测骨龄较为准确。结论利用成人肱骨骨髓腔高度、肱骨近端骨骺骨小梁变化、肱骨大结节内骨小梁变化、锁骨骨髓腔肩峰侧骨小梁变化可推断年龄。Objective To study age-related structural changes of proximal humerusin Chinese Han adults, forthe application inage estimation. Methods Shoulder joint computed radiographs（CR） of 210 Chinese Han adults weresampled, with 124 males aging from 18 to 83 years old and 86 females aging 18 to 60 years old. Four observationindexes （the height of humerus bone marrow cavity, the change of trabecular bone in proximal humeral epiphysis, thechange of trabecular bone in humeral macronodular and the change of trabecular bone in subacromial-clavicular bonemarrow cavity） related with age were observed and scored. The regression equations of age estimation and changescores were established and tested statistically. Results Every index wasclosely correlated with the age changes inadults.The changes of trabecular bone in proximal humeral epiphysis and the changes of trabecular bone in subacromial-clavicular bone marrow cavity have much better effects than the height of humerus bone marrow cavity and thechanges of trabecular bone in humeral macronodular. The regression equations could predict the age of Chinese Hanadults with satisfactory accuracy. Conclusion CR changes of the height of humerus bone marrow cavity, the changesof trabecular bone in proximal humeral epiphysis, the changes of trabecular bone in humeral macronodular and thechanges of trabecular bone in subacromial-clavicular bone marrow cavity can bepracticallyusefulin age estimation forChinese Han adults.
