Abstract Operative surgery concerns itself with the production of therapeutically desirable changes in the anatomy of the body. The introduction of surgery to any special region of the body places its anatomy in a new perspective. Certain anatomical features are of little interest to the surgeon. On the other hand, structures which appear quite insignificant to the pure anatomist frequently are of primary importance to the surgeon. Specifically, he wants to know the substantiality of an individual, tissue in order to be able to use it with confidence. Second, since the surgeon must avoid injury to essential structures , he needs recognisable landmarks which indicate their presence or proximity. Finally, the anatomy as encountered by the surgeon is living and , as such, in motion. He must consider the physical strains and stresses of functional movement as related to the particular anatomy involved as well as the influence of his surgical interference upon them (Zimmerman and Bailey,1962). |
