A key principle in the dissection of human cadavers (sometimes called androtomy) is the prevention of human disease to the dissector.Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique [2] and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses.

Pin tract infection: Because K-wires often pass through the skin into bone they form a potential passage for bacteria from the skin to migrate into the bone and cause an infection. In such cases, the area around the pin becomes red and swollen and may start to drain pus. Usually this infection clears up after removal of the pin.
The latter point was considered important in minimizing the formation of a dissecting hematoma. Once the desired blood was drained from the patient, the operator would place a pin through the edges of the incision. A figure eight of tail hair or thread was then placed over the pin to retain closure. [5]

(e.g. Mayo scissors, Metzenbaum scissors, Pott’s scissors, Iris Scissors).

Numerous pinning techniques have been proposed, however there is not enough evidence to determine which is more effective. [1] Pinning involves the manipulation, with X-ray guidance, of the fracture into an acceptable position, and the immediate insertion of metal pins, called Kirschner wires, through the skin, into one bone fragment and across the fracture line into the other bone fragment.

The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
