118 Injuries of Bone. 



vertebrse, pelvis, and femora — macerated, showing the above. 

 The bones on the fractured side are placed in the position in 

 which they were found on dissection. 



The fracture is of the impacted extra-capsular variety. 

 It will be seen that the great trochanter has been split, and 

 that one of the fragments, along with the shaft of the bone, 

 has been drawn up to the crest of the ilium. The head and 

 neck remain in their normal position. B. C. i. 1. M. 17. 



3. 204. Ununited Impacted Extracapsular Fracture of 

 the Neck, with great Displacement. — Plaster of Paris 



cast of a left innominate bone, and the upper end of the 

 corresponding femur, showing the above. 



As in the last specimen, the great trochanter has been 

 drawn up to the crest of the ilium. The connection between 

 the upper end of the shaft and the ilium was not composed of 

 bone, as it seems to be in the cast. The appearance of bony 

 union is due to a fault in the cast.

3. 205. United Extra-capsular Fracture and Ununited 

 Intra-capsular Fracture of the Neck, with Arthritis 



Deformans. — Upper end of a right femur — macerated, show- 

 ing the above. 



The appearances presented by this specimen are remarkable 

 and unusual. The lower fragment at its upper end has all the 

 appearance of a healed impacted extra-capsular fracture, of the 

 type seen in Nos. 3.199 and 3.200, to the latter of which it has 

 a considerable resemblance. But there is also an ununited 

 fracture of the neck, as well as changes in the upper fragment, 

 such as are produced by arthritis deformans. It is highly 

 probable that arthritis deformans followed the impacted extra-
