The morphology of the growth plate undergoes various transformations during each stage of development, affecting its shape, width, density, and other characteristics. This significantly impacts the distribution of stress in the epiphysis of long bones. To the best of our knowledge, this study represents the first attempt to examine the relationship between growth plate morphology and trabecular bone patterns. Our analysis was conducted using a finite element model and we analyzed two medical cases: trabecular patterns in the femoral epiphysis and the calcaneus bone. Our findings revealed a correlation between the formation of main trabecular groups and growth plate morphology. We investigated how an increased density in high-shear stress zones, which are typically located at the periphery of the growth plate, may occur to prevent failure by shear. This is evident in cases such as slipped capital femoral epiphysis or sever's disease, different simulations align with the clinical data available in the literature from a qualitative and quantitative point of view. Our results suggest that further research should focus on understanding the impact of growth plate morphology on bone remodeling and exploring potential preventive measures for different bone disorders.
生长板的形态在发育的每个阶段都会经历各种转变,影响其形状、宽度、密度和其他特征。这对长骨骨骺中的应力分布有显著影响。据我们所知,本研究是首次尝试研究生长板形态与小梁骨模式之间的关系。我们使用有限元模型进行分析,并分析了两个医学病例:股骨骨骺和跟骨的小梁模式。我们的研究结果揭示了主要小梁组的形成与生长板形态之间的相关性。我们研究了高剪切应力区域(通常位于生长板周边)密度增加是如何发生的,以防止因剪切而失效。这在诸如股骨头骨骺滑脱或Sever病等病例中很明显,不同的模拟从定性和定量的角度与文献中可用的临床数据一致。我们的结果表明,进一步的研究应侧重于了解生长板形态对骨重塑的影响,并探索针对不同骨疾病的潜在预防措施。
