| Abstract Scope |
This study investigates the use of carbon fiber (CF) and glass fiber (GF) polyether ether ketone (PEEK) for an innovative fixation device in cephalomedullary femoral nailing systems. The research builds on additive manufacturing and hybrid material applications to enhance implant stability, durability, and patient outcomes. By combining titanium cores with PEEK composites, the study aims to address failure mechanisms like screw insertion damage, fatigue, and overloading. 3D-printed PEEK models were evaluated under mechanical loading scenarios, simulating clinical conditions. Optical and scanning electron microscopy, along with finite element analysis, were used to assess microstructural integrity and stress distributions at the nail-screw interface. The study incorporates data from advanced regulatory-approved PEEK implants, highlighting their clinical relevance. By integrating additive manufacturing and hybrid designs, this work proposes a new approach to improving femoral nailing systems, offering potential advancements in orthopedic device design to enhance patient recovery and reduce complications. |
