Fracture of the Scapula The Body of the scapula may be broken in cases of injury due to directviolence, the fracture being usually of the fissured or stellate variety whenthe flat surface of the bone is damaged. The vertebral border is occasionallyinvolved in these injuries. The scapula is frequently injured in gunshotwounds ; an injury to the bone may be the only indication that a bullethas passed through the joint. The Spine of the scapula may also be fractured, generally as the resultof direct violence. FRACTURE OF THE SCAPULA 243. Fig. 215.—Sub-coracoid dislocation of tlu- hi-inl of thehuiiierus. The Acromion Process may be broken by direct violence applied tothe point of the shoulder. The arm hangs powerless by the side, and theshoulder is flattened. The irregularity of the bone can be readily detected,and crepitus can be elicited by the elbow and rotating the merely the tipis detached, and then theabove signs will not bepresent. The Coracoid Processis rarely fractured, and onlyfrom direct \iolence. Thereis but httle displacement,on account of the manypowerful ligaments at-tached to it. In spite ofthe attachment of suchpowerful muscles as thepectoralis minor, biceps,and coraco-brachialis, thedisplacement is not great,as the process is kept inposition by the coraco-clavicular ligament. The Neck of the scapula may be fractured immediately behind theglenoid cavity, but this is a rare injury. Its existence has been Cooper and South ha
