Abstract：
Background and Objectives: Bone age determination is a valuable method for forensic and disaster identifications of unknown human remains, as well as for medical and surgical procedural purposes. This retrospective research study aimed to determine the age based on epiphyseal fusion stages and investigate differences related to gender. Materials and Methods: X-rays of the knee were collected from medical imaging centers in hospitals in the south of Jordan and examined by two observers who determined the bone epiphyseal phase of closure for the femur, tibia, and fibula bone ends close to the knee based on a three-stage classification. Results: The main results revealed that females showed earlier epiphyseal union (Stage II) at the lower end of the femur and the upper ends of the tibia and fibula compared to males. In males, the start of complete union (Stage III) at knee bones was seen at the age of 17-18 years, while in females, it was seen at the age of 16-17 years. Additionally, knee bones showed complete union in 100% of males and females in the age groups 21-22 years and 20-21 years, respectively. Although females showed an earlier start and end of epiphyseal complete union than males, analysis of collected data showed no significant age differences between males and females at the three stages of epiphyseal union of the knee bones. Conclusions: Findings of the radiographic analysis of bone epiphyseal fusion at the knee joint are a helpful method for chronological age determination. This study supports the gender and ethnicity variation among different geographical locations. Studies with a high sample number would be needed to validate our findings.
摘要：
背景和目的:骨龄测定是对不明遗骸进行法医和灾难鉴定的一种有价值的方法,以及医疗和外科手术目的。这项回顾性研究的目的是确定基于骨phy融合阶段的年龄，并调查与性别相关的差异。材料和方法：从约旦南部医院的医学影像中心收集膝盖的X射线，并由两名确定股骨闭合骨epi相的观察者进行检查，胫骨,和腓骨的末端靠近膝盖根据三阶段分类。结果：主要结果表明，与男性相比，女性在股骨下端以及胫骨和腓骨上端显示出较早的骨phy结合（II期）。在男性中，在17-18岁时，可以看到膝关节骨完全愈合的开始（第三阶段），而在女性中，它是在16-17岁的时候看到的。此外,在21-22岁和20-21岁的年龄组中，100%的男性和女性膝关节骨骼显示完全愈合，分别。尽管女性表现出比男性更早的骨phy完全结合的开始和结束，对收集到的数据进行分析显示，在膝关节骨的骨连接的三个阶段，男性和女性之间没有显着的年龄差异。结论：膝关节骨epi骨融合的影像学分析结果是确定实际年龄的有用方法。这项研究支持不同地理位置之间的性别和种族差异。需要大量样本的研究来验证我们的发现。
