男性青少年左右侧骨骺愈合推断年龄的差异

目的比较左右侧骨骺愈合差异对推断年龄的影响。方法观察130名男性青少年全身六大关节及骨盆X线片上27个骨骺愈合指标,比较左右侧骨骺愈合程度有差异的部位及级别;左右两侧分别用多元回归方程推算年龄,做比较分析。结果76例左右侧推算年龄一致,47例左、右侧差值小于0.5岁,7例差值在0.50～1.0岁之间,94.6%左右侧推算年龄误差在0.5岁内。左右骨骺愈合差异多见于肱骨近端、桡骨远端、尺骨远端、髂嵴。结论左右愈合度的细微差异对年龄推断无统计学意义。左右骨骺愈合差别不存在一侧的偏向性。

The differences between left & right side development of osteophiphysis in estimating male juvenile age

Objective The influence on age estimation by comparing the differences between left and right side development of osteophiphysis.Methods27osteophiphysis development indexes in the X-ray films of6major joints and pelvises in130male juveniles were Cbserved.The positions and levels of difference between left and right side development of osteophiphysis were compared.The male juvenile age by re - gression equation according to left side and right side were estimated respectively.Results In76cases,the age estimation results are the same for both sides.In47cases,the difference between left and right side is less than6months.In7cases,the difference is between6and12months.The error of94.6%age estimation is within6months.The differences between left and right osteophiphysis development are often found in proximal humerus,distal radius,distal ulna and crista iliaca.Conclusion The subtle differ - ence between left and right osteophiphysis development has no influence on age estimation.
