112 Injuries of Bone. 



The broken surfaces are covered with lymph, or forming 

 fibrous tissue. The capsular ligament is considerably thickened.

3. 190. Extra-capsular Impacted Fracture of the Neck, 



uniting". — Upper end of a left femur — macerated and varnished, 

 showing the above. 



The patient lived for three months after the injury, and the toes 

 were said to have been "inverted." Since, however, the linea aspera is 

 in line with the head, this must have been a misprint for " everted." 



The neck has given way, as usual, at its junction with the 

 trochanters, and these, in turn, have been detached from the 

 shaft, and severely comminuted by the impaction. There has 

 been no union, but new periosteal bone has been formed round 

 the upper part of the shaft and on the fragments of the 

 trochanters. The neck shows some erosion, but no new bone 

 formation. G. C. 174. a.

3. 191. United Extra-capsular Fracture of the Neck.— 



Upper end of a left femur — macerated and varnished, showing 

 the above. 



The neck has given way at the usual place, and its anterior 

 broken border is in front of the upper end of the shaft. 



The upper and back part of the great trochanter and the 

 lesser trochanter have been detached in one piece from the top 

 of the shaft. 



The axis of the neck is horizontal. There has been an 

 unusually great shortening, but very little rotation either way. 

 The greater part of the head and adjacent neck have been 

 absorbed. 



It Avill be observed that while there is much new periosteal 

 bone upon the tipper part of the shaft, there is much less upon
