SERIES 5. INJURIES OF JOINTS. 



DISLOCATIONS OF THE CLAVICLE. 



5. 1. Forward Dislocation of the Sternal End of the 



Clavicle. — Cast in glue and glycerine of the front of the 

 •chest of an adult, showing the above. 



The patient, an elderly workman, was hit on the back of the 

 right shoulder by a passing truck and knocked down. Under chloroform 

 the dislocation was partially reduced, but it was found impossible to 

 retain the bone properly in its place. The patient left the Hospital, 

 however, with a fairly useful arm. 



The projection of the sternal end of the right clavicle is 

 well seen. G. C. 2858.

5. 2. Unreduced Sub-coracoid Dislocation of the Shoulder. 



— Left scapula — macerated,^ showing changes dependent on 

 the above. 



The inner margin of the glenoid cavity has been worn 

 away, and the adjacent bone is rough and irregular. These 

 changes have most probably followed an old-standing sub- 

 coracoid dislocation of the humerus. B. C. ii. M. 46. 



5. 3. Unreduced Sub-coracoid Dislocation of the Shoulder.
