The high demand for biodegradable implants in bone fracture fixations has dramatically increased the use of polymers for biomedical applications as well. However, the replacement of stainless steel and titanium screws by biodegradable materials represents one of the most critical aspects of biomechanics. In this study, the mechanical behavior of polycaprolactone (PCL) in tension and compression is examined. Driven by the advanced technology of computational mechanics, the fixation of the posterior malleolus fracture has been designed and analyzed. The core idea depicts the static analysis of screws made of PCL fixed in the ankle joint. The focus of the study is on this bio-absorbable, polymer-based material performance under constant compression. Parametric analysis is employed for the optimization of the PCL scaffold. Future studies will focus on the experimental verification of the numerical analysis results.
对用于骨折固定的可生物降解植入物的高需求也极大地增加了聚合物在生物医学应用中的使用。然而，用可生物降解材料替代不锈钢和钛螺钉是生物力学中最关键的方面之一。在本研究中，研究了聚己内酯（PCL）在拉伸和压缩时的力学行为。在计算力学先进技术的推动下，设计并分析了后踝骨折的固定方式。核心思想描述了由PCL制成的螺钉固定在踝关节中的静态分析。该研究的重点是这种基于聚合物的生物可吸收材料在恒定压缩下的性能。采用参数分析来优化PCL支架。未来的研究将集中在数值分析结果的实验验证上。
