Where from injury in a muscular patient a long anterior flap cannot be had, recourse should be had at once to the operation at the seat of election, rather than run the risk of pressure on the cicatrix by using a double flap operation, or trust that broken reed, the long posterior flap from the great muscles of the calf. In June 1865, Mr. Henry Lee described a method of operating which he hoped would unite the benefits of Mr. Teale's method to the ease of performance of the old flap from the calf. I append a short account of his method. From its position, however, it has the great disadvantage of retaining the discharges, and by its weight straining the stitches and weighing down the cicatrix:-- LEE'S AMPUTATION _of the Leg by a long rectangular flap from the Calf_.--The operation described was performed according to Mr. Teale's method, as far as the external incisions were concerned, but the long flap was made from the back instead of from the front of the limb (Plate IV. figs. 14, 15). Two parallel incisions were made along the sides of the leg, these were met by a third transverse incision behind, which joined the lower extremities of the first two. These incisions, which formed the three sides of the square, extended through the skin and cellular tissue only. A fourth incision was made transversely through the skin in front of the leg so as to form a flap in this situation, one-fourth only of the length of the posterior flap. When the skin had somewhat retracted by its natural elasticity, an incision was made through the parts situated in front of the bones, which were reflected upwards to a level with the upper extremities of the first longitudinal incisions. The deeper structures at the back of the leg were then freely divided in the situation of the lower transverse incision. The conjoined gastrocnemius and soleus muscles were separated from the subjacent parts, and reflected as high as the anterior flap. The deeper layer of muscles, together with the large vessels and nerves, were divided as high as the incision would permit, and the bones sawn through in the usual way. The flaps were then adjusted in the manner recommended by Mr. Teale.[42] The patients were able to bear the weight of the body on the end of the stump. In cases of chronic disease, where the muscles are atrophied and condensed, the following posterior flap method may be used with advantage. It is approved of by Mr. Spence. An incision is made across the front of the leg from the _posterior edge_ of the fibula to the _posterior edge_ of the tibia, or _vice versâ_, according to the limb. The limb is then transfixed behind the bones from the same points, and a long and gently rounded posterior flap cut. The bones are then cleaned, and cut through at a little higher level.
