Here,where there are no muscles, the deep fascia is broughtdirectly over the sawn surface of the bone so that the skinmay be freely movable. Wilms attains the latter objectby interposing the tendo Achillis between the flap andthe end of the bone. We merely mention that Ollier andKummer use the skin of the heel as a covering for thestump to ensure that it will be able to bear weight, whileKummer waits until it has become contracted by theformation of granulation tissue.
