1859.] Dugas, on Fracture of Hie Scapula. 743constituted the treatment to which the patient had been subjectedprior to my seeing him.Examination.— By causing the boy to st<strong>and</strong> erect before me,with his chest bare, the left shoulder appears drooped, emaciated<strong>and</strong> very much flattened. The deltoid muscle feels loose<strong>and</strong> flabby, as though in a state of atrophy. This is not so perceptiblein the other muscles connected with the shoulder;the supra-spinatus, infra-spiriatus <strong>and</strong> pectoralis major are evidentlysmaller here than on the other side. The acromionprocess projects in a sharp angle, <strong>and</strong> the head of the humerusis depressed about three-fourths of an inch ;but may be easilyreplaced by pushing up from the elbow. The left h<strong>and</strong> can becarried upon the right shoulder while the elbow rests againstthe thorax, thereby precluding the idea of a dislocation properlyso-called.By grasping the head of the humerus, which is distinctly felt,with one h?nd, <strong>and</strong> rotating the lower end of the bone with theother h<strong>and</strong>, it is found that the head moves continuously w r iththe shaft, <strong>and</strong> without any crepitation whatever. There istherefore no fracture of the humerus at any point.By placing one h<strong>and</strong> upon the shoulder so as to fix the bodyof the scapula, the acromion process <strong>and</strong> the clavicle, at thesame time that various movements upward <strong>and</strong> laterally areimparted to the humerus, very distinct crepitation can be perceivedin the shoulder-joint. Crepitation is also distinctlyinduced by grasping the head of the humerus with the ends ofthe fingers resting upon the margin of the glenoid cavity in theaxilla, where it is easily felt in this case, <strong>and</strong> moving simultaneouslyboth the head <strong>and</strong> the glenoid cavity,the scapula is fixed as above mentioned.yetwhile the body ofThere must then bea solution of continuity somewhere between the glenoid cavity<strong>and</strong> the body of the scapula.The coracoid process is here very distinctly felt, <strong>and</strong> it doesnot follow the movements of the humerus when this is alternatelycarried up into its proper position <strong>and</strong> allowed to fall.By placing the fingers upon the coracoid <strong>and</strong> the acromion processesthey are found to move in unison with the lower angleof the scapula without crepitation, <strong>and</strong> are therefore continuouswith it, showing that the fracture must implicate some pointbetween the glenoid cavity <strong>and</strong> the root of thecoracoid pro-
