“…Richmond et al [18] studied the phalanges' curvature during grasping with a FE model and concluded to the great influence of the curvature on the computed strain. Ezquerro et al [19] developed a FE model of the carpal scaphoid and its joints to study the most efficient configuration of scaphoid fractures fixation devices (Kirschner wires). Recommendations of the positioning of such device are evaluated with FE models, in order to improve the scaphoid fracture fixation.…”

This paper investigates a biomechanical aspect of human hand during grasping, using the finiteelement method. A realistic three-dimensional finite-element (FE) model of a human hand is developed, including wrist bones, phalanges, soft tissues and skin, reconstructed from medical computed tomography (CT) scan images. Material laws of the literature have been implemented in the model, in order to be able to simulate a simple activity of grasping. In a human design context, this model allows an interesting biomechanical study, which simulates the grasping task in a biofidelic manner. This model is a first step in the modeling of the human hand that can lead to future studies dealing with the interaction of the hand with its environment for the improvement of safety requirements of future products development.

“…The screw must be as perpendicular as possible to the fracture to induce maximal compression forces and minimal shearing forces, thereby optimizing the stability of the fixation. 6 Compression loading is an important factor for bone healing. [7][8][9][10] Percutaneous screw fixation for scaphoid-waist fractures can be performed through a volar approach [11][12][13][14][15][16] or through a dorsal approach.…”
