In every case the abdominal tourniquet will be found of great service in checking hæmorrhage, during the operation of amputation at the hip-joint. It consists of an arch of steel fitted with a pad behind, which rests against the vertebral column, and a pad in front playing on a very fine and long screw, through an opening in the arch. When screwed down tightly on the aorta just before the incisions are commenced, it checks hæmorrhage admirably without injuring the viscera. When this is applied, a method of amputation once practised by Mr. Syme, though not so rapid as the double-flap method by transfixion, will be found very easy, and to result in most excellent flaps. He cut an anterior flap in the usual manner by transfixion, then made a straight incision from its outer edge down to about two inches below the great trochanter, thus exposing it fully, and from the lower end of this incision transfixed again, cutting a posterior flap nearly equal in size to the anterior; a few strokes of the knife round the joint finished the disarticulation. The resulting flaps came together with great accuracy, and were not burdened with the great unequal masses of muscles so often noticed in the posterior flaps which are made by cutting from within outwards _after_ disarticulation. In some cases of amputation where the femur has been badly shattered, it is a good plan to amputate through the upper third of thigh, tie all the vessels, and then, aided by an incision at outer side, dissect out the head of the bone. Mr. Furneaux Jordan of Birmingham carries out this principle by first dividing the soft parts in circular direction low down the thigh, and then dissecting out the head of the bone from the muscles by a long incision on the outer aspect of the limb. _Note._--In severe cases of smash when both lower limbs have required amputation, the author has derived much assistance from the method of managing the operation detailed below:-- _Double Primary Amputation of (both) Thighs from railway smash_--_Rapid recovery._--G., a healthy-looking man, aged twenty-seven, but looking much older, while driving a horse near Granton, caught his foot on the edge of a rail at a point, fell, and both his legs were run over by several loaded wagons. A special engine was procured, his thighs tightly tied up, and he was sent up to hospital at once. I was in hospital at the time, so with as little delay as possible he was placed on the operating table, and the necessity for amputation being too evident, I obtained his leave to remove both his legs above the knee; but his pulse was very feeble, and he was intensely nervous, throwing his arms wildly about, panting for breath, and looking very ill, cold, and exhausted.
