Abstract

Plate fixation is the primary treatment for clavicle fractures, but standard plates often fail, requiring reoperation due to irritation, bending, or fracture. These issues are linked to poor geometric fit suboptimal plate thickness, and material performance. This study proposes a personalized clavicle plate design methodology for middle one-third fractures. Using a reverse engineering approach, a 3D model of a 15-B1.2 oblique fractured clavicle bone is created from CT scan data. Customized plates of varying thicknesses are designed and simulated using titanium, stainless steel, and cobalt-chromium-molybdenum alloys. This research proposes a methodology based on finite element modeling (FEM) to assess structural stability, safety, and fatigue life by analyzing stresses and displacements under diverse loading conditions. This investigation aims to improve clinical decisions and patient outcomes through personalized treatments and enhanced fracture stability.

定制固定钢板治疗中三分之一锁骨骨折的数值设计与分析。

钢板固定是锁骨骨折的主要治疗方法，但标准钢板常因刺激、弯曲或骨折而失效，需要再次手术。这些问题与板厚不理想的几何配合和材料性能有关。本研究提出针对中三分之一骨折的个性化锁骨钢板设计方法。使用逆向工程方法，根据CT扫描数据创建15-B1.2斜向锁骨骨折的3D模型。不同厚度的定制板的设计和模拟使用钛，不锈钢和钴铬钼合金。本研究提出了一种基于有限元建模（FEM）的方法，通过分析不同载荷条件下的应力和位移来评估结构的稳定性、安全性和疲劳寿命。本研究旨在通过个性化治疗和增强骨折稳定性来改善临床决策和患者预后。
