目的对肱骨上端骨松质长度和骨松质指数进行年龄鉴定。方法随机拍摄１０～９３岁１７７例（男９０例，女８７例）汉族人上肢双侧肩部前后位Ｘ线片。每个性别的观察对象分成９个年龄组，分别测量Ｘ线片上肱骨上端骨松质长度，计算肱骨上端骨松质指数。结果肱骨上端骨松质长度与指数随年龄增长逐渐变小，与年龄呈高度负相关。根据肱骨上端骨松质长度和指数与年龄的关系得出回归方程。结论利用肱骨上端骨松质长度和骨松质指数可为年龄鉴定提供一种新方法。
Objective To identify the age of upper humeral bone length and cancellous bone index. Methods A total of 177 cases (90 males and 87 females) aged 10-93 years were enrolled in X-ray films of bilateral upper and lower extremity shoulders. The subjects of each gender were divided into 9 age groups, and the length of the cancellous bone on the upper humerus was measured and the index of the upper humerus cancellous was calculated. Results The length and index of cancellous bone in the upper humerus gradually became smaller with age and showed a highly negative correlation with age. The regression equation was derived from the relationship between the length of the humeral superior cortical bone and the index and age. Conclusion The use of upper humeral bone length and cancellous bone index for identification of age provides a new method.
