A device used to support a HERNIA; or to retain the protruding organ within the cavity from which it tends to pass. Every truss possesses a pad of some sort to cover the opening and a belt or spring to keep it in position.
Before applying a truss the wearer must make certain that the hernia has been reduced; this may mean lying down beforehand. A truss will rarely control a hernia satisfactorily, and it should be considered as a temporary measure only until surgical correction is possible. In the past, trusses have been supplied to patients considered too frail for surgery, but modern anaes-thetic techniques mean that most people can have their hernias surgically repaired.
