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.
For example, a fracture at the end of the fibula is called a lateral malleolus fracture, or if both the tibia and fibula are broken, it is called a bimalleolar fracture. Two joints are involved in ankle fractures: Ankle joint - where the tibia, fibula, and talus meet.
