In the management of wounds and other surgical conditions it is
necessary to eliminate various extraneous influences which tend to delay
or arrest the natural process of repair.
Of these, one of the most important is undue movement of the affected
part. "The first and great requisite for the restoration of injured
parts is _rest_," said John Hunter; and physiological and mechanical
rest as the chief of natural therapeutic agents was the theme of John
Hilton's classical work--_Rest and Pain_. In this connection it must be
understood that "rest" implies more than the mere state of physical
repose: all physiological as well as mechanical function must be
prevented as far as is possible. For instance, the constituent bones of
a joint affected with tuberculosis must be controlled by splints or
other appliances so that no movement can take place between them, and
the limb may not be used for any purpose; physiological rest may be
secured to an inflamed colon by making an artificial anus in the caecum;
the activity of a diseased kidney may be diminished by regulating the
quantity and quality of the fluids taken by the patient.
