Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement. Reduction could be by closed or open methods. 1  Open reduction refers to the method wherein the fracture fragments are exposed surgically by dissecting the tissues.2  Closed reduction refers to manipulation of the bone fragments without surgical exposure of the fragments.his sense of the term reduction does not imply any sort of removal or quantitative decrease but rather implies a restoration: re (back [to normal]) + ducere (lead/bring), i.e. , bringing back to normal..
