In cases of extensive laceration of the soft parts, all soiled, bruised, or torn portions of tissue should be clipped away with scissors, blood-clots removed, and the bleeding arrested by forci-pressure or ligature. If there is any reason to believe that the wound is infected, any fragments of bone completely separated from the periosteum should be removed. In comminuted fractures, extension applied by strips of plaster or by means of ice-tong callipers or Steinmann's apparatus (p. 150) often facilitates replacement of the fragments and their retention in position. Plates and screws are not recommended for comminuted fractures, owing to the mechanical difficulty of fixing a number of small fragments and the risks of infection. The wound should be purified with eusol, and the surrounding parts painted with iodine. On the whole, it is safer not to attempt to obtain primary union by completely closing such wounds, but rather to drain or pack them. To increase the local leucocytosis and so check the spread of infection, a Bier's constricting bandage may be applied. In other respects the treatment is carried out on the same lines as in simple fractures, provision being made for dressing the wound without disturbance of the fracture. Massage and movement should be commenced after the wound is healed and the condition has become analogous to a simple fracture. #Question of Amputation in Compound Fractures.#--Before deciding to perform primary amputation of a limb for compound fracture, the surgeon must satisfy himself (1) that the attainment of asepsis is impossible; (2) that the soft parts are so widely and so grossly damaged that their recovery is improbable; (3) that the vascular and nervous supply of the parts beyond has been rendered insufficient by destruction of the main blood vessels and nerve-trunks; (4) that the bones have been so shattered as to be beyond repair; and (5) that the limb, even if healing takes place, will be less useful than an artificial one. In attempting to save the limb of a young subject, it is justifiable to run risks which would not be permissible in the case of an older person. To save an upper limb, also, risks may be run which would not be justifiable in the case of a lower limb, because, while a serviceable artificial leg can readily be procured, any portion of the natural hand or arm is infinitely more useful than the best substitute which the instrument-maker can contrive. The risk involved in attempting to save a limb should always be explained to the patient or his guardian, in order that he may share the responsibility in case of failure.
