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.rom its origin, it descends along the lateral edge of the leg as a thin strap of muscle in the lateral compartment of the leg....
