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.
Background. Lower leg fractures include fractures of the tibia and fibula. Of these two bones, the tibia is the only weightbearing bone. Fractures of the tibia generally are associated with fibula fracture, because the force is transmitted along the interosseous membrane to the fibula.The skin and subcutaneous tissue are very thin over the anterior and medial tibia and as a result of this, a significant number of fractures to the lower leg are open.he tibia and fibula articulate at the proximal tibia-fibular syndesmosis. Fractures of the tibia can involve the tibial plateau, tibial tubercle, tibial eminence, proximal tibia, tibial shaft, and tibial plafond. See the image below. Shown is an intra-articular fracture of the medial condyle of the tibial plateau.
