Abstract Scope |
This study investigates the use of carbon fiber polyether ether ketone (CF PEEK) and glass fiber polyether ether ketone (GF PEEK) materials in a novel fixation device for fractured cephalomedullary femoral nailing systems. Previous models have shown failure mechanisms related to damage during screw insertion, fatigue, and overloading. The objective is to enhance system integrity and performance by utilizing these materials, mitigating risks of damage, fatigue, and overloading. Experimental work on 3D-printed models is conducted, analyzing mechanical properties under loading conditions. Optical and scanning electron microscopy are used. Finite element analysis is employed to understand stresses in the nail and screw interface. Insights inform a new fixation device design focusing on material properties to resist damage and fatigue. This study presents an innovative approach to improving the stability and durability of femoral nailing systems. |
