S2 Injuries of Bone. 



3. 101. United Fracture of the outer end of the Clavicle. 



— Plaster of Paris cast of a left clavicle, showing the above. 



The bone has been broken through at the line of attach- 

 ment of the trapezoid ligament. The outer fragment shows the 

 characteristic displacement forwards without any depression.

FEACTUKES OF THE SCAPULA. 



3. 102. Ununited Fracture of the Acromion Process and 

 United Fracture of the Vertebral Border.— Left scapula 



of an adult — macerated — showing the above. 



The acromion process has been separated from the spine, 

 and the margins of the bone are thickened where the pieces 

 meet. The fracture at the inferior angle has extended to the 

 vertebral border, and the pieces have united with considerable 

 displacement. The injury to the acromion might, from the 

 position and direction of the line of separation, have been an 

 ununited epiphysis, but the raised margins of bone and the 

 presence of a fracture at another part of the bone render the 

 theory of fracture more probable. B. C. I. 1. M. 7b. 



3. 103. Supposed Fracture of the Acromion Process of 



the Scapula. — Right scapula — macerated — showing an irre- 

 gular groove between the acromion process and the rest of the 

 bone. 



This is possibly a late union of the epiphysis.
