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.
Fractures of the lower end of the tibia and fibula are covered in ankle fractures. Fractures of the upper end of the tibia are covered in knee fractures.The tibia bone is the largest and most important bone of the lower leg. It is quite vulnerable to injury.n the case of an isolated fracture of the fibula you may be able to walk, but with nearly all other fractures it is impossible to bear weight. Within a few minutes of the injury the leg will swell up. If there have been injuries to the nerves or arteries the foot may be numb or cold.
