We investigated the finger design and kinematics, mechanical joint coupling, and actuation methods of these commercial prosthetic hands. The empirical findings are supplemented with a compilation of published data on both commercial and prototype research prosthetic hands. We discuss numerous mechanical design parameters by referencing examples in the literature. Crucial design trade-offs are highlighted, including number of actuators and hand complexity, hand weight, and grasp force.
  The fibula is commonly known as the calf bone. It's the weight-bearing bone that extends to the ankle from the knee. It runs parallel to the tibia, which does is not w â¦ eight-bearing.he fibula is connected by a synovial joint to your other shin bone, the tibia. The â¦ fibula is what makes your outer ankle bone. And the tibia makes your inner 'ankle' bone. The main job of the tibia is to form a hinge joint with the femur, which allows you to walk, run, kick a ball, and generally have fun.
Peroneus Longus Muscle The peroneus longus muscle, whose name means âlong muscle of the fibulaâ is a major muscle of the lower leg that plantar flexes and everts the foot at the ankle. Also known as the fibularis longus, it is the longest muscle that attaches to the fibula and is used specifically when balancing oneâs weight on one foot. The peroneus longus muscle has its origin along the lateral edge of the head and proximal shaft of the fibula, just below the styloid process of the fibula.
