The forearm is then slightly flexed, the fleshpinched up and transfixed down to the bone close to thejoint through the beginning of the preceding incision,and the knife carried downward and forward along thesame line to the completion of the flap. The flap isthen drawn upward and disarticulation is performed thesame as before. The union of the borders of the wound results in a poste-rior cicatrix. The Posterior Ellipse.—In this method the points of the ellipse arereversed, the flap being taken from the posterior surface. There is nothing.

In this amputation adrainage tube should be employed for the first few days of the treatment. The Circular Method.—Lay out the flaps obliquely, measuring from thecondyles—four inches below the outer and two and a half inches below theinner condyle. Divide the superficial tissues obliquely down to the fascia
