目的通过观察分析锁骨内侧骨骺的愈合情况,评价其在年龄推断中的作用。方法收集343对已知年龄和性别的尸体锁骨,以1岁为组,观察分析锁骨内侧端骨骺愈合亭台变化,根据软骨细胞失去增值能力,骺软骨骨板被骨组织所代替情况进行分级分析,对所得数据进行统计学分析,按17～30岁和31岁以上年龄分组进行比较。结果男性和女性的锁骨最早于18岁开始愈合,22岁愈合完全。完全愈合时间在男性最迟为32岁,而女性为31岁。不同性别的骨骺愈合情况在两个年龄组中存在显著差异(P<0.01)。结论锁骨骨骺愈合情况随年龄的增长呈规律性变化,特别是17～32岁年龄段,根据锁骨骨骺愈合情况推断年龄,在法医学实践中有应用价值。
Objective To observe the healing of the medial clavicle epiphysis and evaluate its role in age estimation. Methods A total of 343 corpse clavicles of known age and gender were collected. The changes of the epiphyseal calmetry in the medial clavicle were observed and analyzed. The epiphyseal cartilage plate was replaced by the bone tissue according to the loss of proliferative capacity of the chondrocytes. , The data were statistically analyzed, according to the age of 17 to 30 and 31 years of age grouping for comparison. Results Male and female clavicles began to heal as early as age 18 and healed completely at 22 years of age. The complete healing time is at the age of 32 for males and 31 for females. Epiphyseal healing of different genders in the two age groups there is a significant difference (P <0.01). Conclusion The situation of clavicle epiphyseal healing changes regularly with age, especially in 17 ~ 32 age group. According to the circumstance of clavicle epiphyseal heal, we can infer the value of age in forensic practice.
