The practice of surgery : embracing minor surgery and the application of dressings, etc., etc., etc. . —This operation may be per-formed either by the circular method, as proposed by Abernethy,the oval process of Cornuau, or the double flap. Flap Operation—Process of Liston.—By forming the flapsfrom the anterior and posterior aspects of the limb, the bone maybe exposed and sawed at the inner trochanter, or it may be removedat the joint. In making the incision thus high, the common femoralis compressed, as it passes over the brim of the pelvis, and an assis-tant must follow the knife with his hand, and grasp firmly theanterior flap, whilst others are ready to compress the vessels in theposterior, so soon as the sawing or disarticulation is completed. These operations must be undertaken with determination andcompleted rapidly, in order that dangerous effusion of blood maybe prevented ; they are not to be attempted without great conside-ration, and only under very pressing circumstances. The fore part of the articulation is fully exposed immediately onthe anterior flap being The capsular ligament is cut by drawing the knife across deter-minately, as if it were the intention of the operator to cut off thehead of the bone. The round ligament and the posterior portionof the capsule are cut; and the blade of the instrument havinwbeen passed behind the neck and trochanters, the posterior flap isquickly formed, so as to allow the limb to drop. The vessels onthe posterior aspect are first tied; then the femoral, and those in 14* 162 AMPUTATION AT THE HIT JOINT. the anterior flap, which had been commanded by the assistant, areuncovered one by one, and secured. Process of Lisfranc.—The flap may be first formed by trans-fixion and cutting outwards, then opening the joint and carryingthe knife around the bone, so as to divide transversely, or withsuch obliquity as the state of the parts will allow, the tissues onthe opposite surface of the limb.
