Assessment of Internal Fixation Implants for Treating Vertical Femoral Neck Fractures through Finite Element Analysis

Objective: This research primarily focuses on understanding the application of internal fixation implants in the treatment of Pauwels Type-3 vertical Femoral Neck Fractures (FNF). The main objectives encompass understanding the application of four distinct types of implants, assessing the impact of these fixation techniques on the femur bone, and comparing the efficacy of the implants using finite element analyses (FEA). Methods: Four types of internal fixation implants were examined: Cannulated screws in the inverted triangle (CSIT). Fixation by four screws. Dynamic hip screw with derotational screw system (DHS+DS). Proximal femoral locking plate system. The comparative effectiveness of these implants was determined using finite element analyses (FEA). Results: The research revealed that the DHS+DS implant exhibited superior performance when compared to other internal fixation implants. Conclusion: For the treatment of Pauwels Type-3 vertical FNFs, the DHS+DS implant demonstrates enhanced efficacy, potentially making it the most appropriate technique for such fractures. ABSTRACT
