Tiien a catlin is to be passed between the bones, so as to divide the interosseous ligament and muscles ; a three-tailed retractor is then to be applied, and the bones sawn through together. If the spine of the tibia projects much, it can be removed by a fine saw, or bone-nippers. The vessels are to be secured, and the stump treated as in amputation of the thigh, the integuments being brought together in a straight line. Flap Operation.—This is generally preferred, and is thus per- formed. The surgeon first places the heel of the knife on the side Fig. of the limb, farthest from him, and draws it across the front of the limb, in a semicircular direction, making a semilunar flap. When its point has arrived at the opposite side, it is at once made to trans- fix the limb, and then the larger and posterior flap is cut. Tn trans- fixing the limb, care must be taken not to pass the knife between the bones. This amputation may also be performed near the ankle ; but, in this instance, it will be necessary to shorten the tendo Achil- iis after the flap is made. The leg should not be amputated nearer the knee than the tuberosity of the tibia, or the joint will be opened, and inflammation result. Hence amputation at the kfiee is rarely performed, although disarticulation may be readily performed with a large scalpel. In this operation the patella should be allowed to remain. AMPUTATION OF THE FOOT. The foot is amputated at two places. Choparlh Operation.—A flap is made from the upper part of the instep, and the disarticulation commenced immediately behind the tuberosity of the scaphoid bone. The bistoury is passed between the scaphoid and head of the astragalus, and then between the cu-. Please note that these images are extracted from scanned page imag
