The Design and Optimisation of W-Angular Plate on Quadrilateral Surface

This study focuses on the design, optimization, and biomechanical evaluation of a W-angular hip plate intended for the quadrilateral surface of the human pelvis. The W angular configuration is chosen for its potential to enhance stability and load distribution across the complex pelvic anatomy. The primary objective is to investigate and refine the screw insertion technique that maximizes the plate's stability on the quadrilateral surface. This involves evaluating various parameters such as screw placement angles and depths to achieve optimal fixation. Mechanical behavior of the W-angular hip plate is comprehensively assessed under diverse loading conditions simulating activities essential to daily living, including walking, standing, and sitting. The evaluation encompasses the analysis of stress distribution, strain patterns, and deformation characteristics within the implant structure. Both male and female anatomical variations are considered to ensure a thorough assessment of performance across different patient demographics. The outcomes of this study aim to deepen the understanding of how the W-angular hip plate interacts with the pelvic bone and surrounding tissues under realistic conditions.
