194 Injunes of Joints. 



The patient, a strong man, had fallen over a gi-eat height, and had 

 received severe internal injuries, from which he died shortly after his 

 admission into the Royal Infirmary. 



The deltoid has been thrown down to expose the region of 

 the shoulder. The head of the humerus was displaced 

 backwards into the infra-spinatus fossa, and is seen lying on 

 the infra-spinatus muscle. The capsule of the shoulder-joint 

 and the attachment of all the muscles to the two tuberosities, 

 except a small portion of the teres minor, were completely torn 

 off. The surrounding muscles and areolar tissue were infiltrated 

 with blood. Prepared by G. Hardyman, M.B. G. C. 3580.

5. 9. Forward Dislocation of the Head of the Radius. — 



Glue and glycerine cast of a fore-arm and part of an upper arm, 

 showing the above. 



The bone had been dislocated some years before, and had never 

 been reduced. The arm was, however, quite useful, except that flexion 

 was limited. 



The cast shows the projection of the head of the radius, 

 which occurred during flexion. G. C. 3202.

DISLOCATION OF THE HAND AND FINGEES. 



5. 10. Backward Dislocation of the Second Metacarpal 



Bone. — Cast, in glue and glycerine, of a right hand, showing 

 the above. 



The patient was a ticket -of-leave man. The accident occurred in 

 the course of a fight. An attempt at reduction without chloroform 

 failed, and the patient left the Infirmary before any further treatment 

 could be tried. 



The cast shows the projection of the base of the bone at 

 the carpus, and the sinking in of the head of the bone at the 

 knuckle. G. C. 2867.
