Development of a Comprehensive Linear Finite Element Model of the Human Wrist Joint

This study presents a linear finite element model for the human wrist, constructed from a CT scan of a 68-year-old male (type I wrist). This model intricately captures the bones, soft tissues, and ligaments to study the biomechanics of static grasping by applying pressure loads on the five metacarpals. The results show radial transmission of the load, consistent with findings from wrist finite element models conducted in the last decade and other experimental in vitro studies. Validation is explored through the assessment of carpal resultant displacement. Our preliminary results confirm the model’s efficacy in reproducing key biomechanical aspects, laying the groundwork for future investigations into ongoing wrist biomechanics challenges.
