[History of surgical instruments: 8. Instruments and development of amputation technique exemplified by amputation sets from the middle of the 19th century].
The amputation of a limb is one of the oldest surgical procedures. However, in the course of medical history operative techniques and surgical instruments have been improved continuously. With an example of an amputation case of the last century we will summarize this development until the middle of the nineteenth century. Even in the first century Celsus gave a description of an amputation (circular cut). A major step in the development of the operative technique was the introduction of artery forceps by A. Paré in the sixteenth century. Nevertheless, due to a lack of analgesics and narcotics the operation had to take only a few minutes. Therefore the amputation was completed in one cut, i.e. detachment of the skin, muscles and bone at the same level. This technique known as "classic circular cut" was modified several times in the following period: in order to reduce suture tension Petit recommended to transect the skin first and the muscles and bone more proximal ("two-stage circular cut", 1718) and Bromfield approved to cut in turn the skin first, the muscles more proximal and the bone most proximal ("three-stage circular cut", 1773). Finally, Lowdham (1679), Verduyn (1696) and C. J. M. Langenbeck (1810) changed the operative technique to the effect that they used a soft-tissue flap in order to cover the bone without tension ("flap amputation").
