摘　　要：目的探讨四川省藏族青少年膝关节骨发育趋势,更新利用膝关节骨龄推断我国藏族青少年活体年龄的数据资料。方法在我国四川省阿坝地区调查483例14~19周岁藏族男、女性青少年膝关节X线片,选取股骨远端、胫骨近端及腓骨近端骨骺作为骨骼发育指标,观察骨骺发育情况,并运用SPSS 16.0统计学软件计算出青少年膝关节骨骺闭合年龄的描述性数据。结果膝关节中,闭合最早的骨骺是股骨远端骨骺,闭合最晚的是腓骨近端骨骺,其中女性青少年膝关节骨骺发育较男性提前约1岁左右。结论应用于法医学活体骨龄鉴定的藏族青少年相关数据资料应定期更新。本研究结果可为法医学、人类学及临床医学等相关学科在进行骨龄评价时提供参考。Objective To discuss bone development trend in the knee joint of Tibetan teenagers in Sichuan province and to effectively update the database for estimating the living age of Tibetan teenagers in terms of bone age of the knee joint.Methods Radiographs including epiphysis of distal femur,proximal tibia and proximal fibula were taken from 483 Tibetan male and female teenagers aged from 14 to 19 years old in Aba prefecture of Sichuan province in order to observe epiphyseal growth situation.The descriptive data of the epiphyseal closure ages of these teenagers’ knee joints were statistically analyzed by SPSS 16.0 software.Results The distal femur epiphyseal closure occurred earliest,while the proximal fibula epiphyseal closure occurred latest.The epiphyseal growth of knee joints of females occurred about one year earlier than that of males.Conclusion The forensic information and data related to Tibetan teenagers’ bone age identification should be updated regularly.These results provide potential value for the practice of forensic medicine,anthropology and clinical medicine.
