Finite element analysis demonstrates the impact of coatings on mechanical properties in intertrochanteric fractures, suggesting optimal material selection.
In this study, the biomechanical performance of four different coating materials applied on 316L stainless steel Schanz screws used in the treatment of intertrochanteric fractures (ITF) was examined by finite element analysis (FEA). Coatings: hydroxyapatite (hA), hexagonal boron nitride (hBN), zirconium dioxide (ZrO 2 ), and aluminum oxide (Al 2 O 3 ). How these coatings affect the mechanical properties, durability, and biocompatibility of screws reveals the potential to increase the effectiveness of external fixators. Analyses aim to make recommendations for safer and more effective applications during the treatment process by examining the effects of each coating on stress distribution, deformation and stress parameters. Ultimately, the most suitable material selection for fracture healing depends on clinical needs and the patient's condition. If high stress transmission is required, 316L or 316L‐hA may be preferred. If more stable and low shear performance is desired, 316L‐ZrO 2 or 316L‐Al 2 O 3 coatings might be considered. In any case, it is essential to take all parameters into account when choosing the material.
