106 Injuries of Bone. 



impaction. 2. Crepitus, although looked for, was absent 

 immediately after the accident, although against this it is 

 right to set the shortening, which could apparently be overcome. 

 3. The great shortening of the neck and its impaction into the 

 head are distinctly seen, especially above, while there is no 

 appearance of impaction of the neck into the great trochanter. 

 As is usual in impaction near the head, the outer fragment has 

 been driven into the inner one. The capsule seems thickened. 

 The lower fragment has been everted, and the trochanter 

 is almost on a level with the head. The bone is condensed 

 in the head and at the line of fracture. G. C. 746.

3.173. United Intra-capsular Fpaeture of the Neck.— 



Anterior half of the preceding specimen, muscles dissected off 

 — in spirit, showing the above. 



In addition to indications of impaction seen also in the 

 previous specim.en, this one shows in another way the eversion 

 which was present. The head has been pushed back from 

 the front of the neck, thus allowing the upper end of the 

 lower fragment to project in front. The front of the capsule 

 seems also thickened. In both specimens the cartilage covering 

 the head is seen to be eroded as in arthritis deformans.

3. 174. United Intra-capsular Fracture of the Neck.^ 



Anterior half of the upper end of a right femur — muscles 

 cleaned off, and in spirit, showing the above. 



The line of fracture within the capsule is quite distinct.. 

 There has been shortening and eversion, but not impaction. 

 The cancellated tissue has been re-formed, except at the lower part 

 of the neck, where the new bone is condensed. G. C. 2461.
