    CHAPTER V ON CONTRACTION OF SCAR TISSUE AND COMPOUND INJURIES ABOUT JOINTS The behaviour of large and deep scars has been studied mainly in connexion with bruises and burns. In the present war there have been a large number of extensive wounds from shell hre and compound wounds of bones and joints with large exit wounds. Moreover, there has been added a great deal of phlegmonous and gangrenous change in the tissues, leading to considerable loss of tissue. There has, therefore, in the last nine months been ample oppor¬ tunity of applying the lessons learned in civil practice and to test their truth. It is necessary to take a brief view of the histo¬ logical changes going on at the site of the wound, and to see how they are to be controlled in order to prevent stiffness of joints and mechanical disabilities due to the contracting scar. Roughly one may divide the process of repair, whether in epithelium, connective tissues generally, or bone in particular, into three stages. First: Early repair processes include the removal of dead tissues, sloughs, and necroses, and the establishment of an active hyperaemia with the formation of new loops of blood-vessels permeating the mass of blood-clot, exudate, and damaged tissues.
