70 Injuries of Bone. 



cervical vertebra has been dislocated forwards ; on the right 

 side the lower articular process with adjacent part of lamina 

 has been broken from the rest of the bone. 



There has been a slight fracture of the upper part of the 

 body of the seventh cervical vertebra, especially towards the 

 left side. G. C. 173a.

3. 75. Dislocation between the last Cervical and first 



Dorsal Vertebrae. — Last three cervical and upper three 

 dorsal vertebrae, with the muscles cleaned off — in spirit — 

 showing the above dislocation. 



' ' The man fell headlong from a barge lying aground in the Thames. 

 His head stuck in the mud, and the whole weight of his trunk and limbs 

 was thrown on the neck, and an obliquity in the direction of the force 

 probably twisted the vertebrte. He died instantly." 



There seems to be no indication of fracture. The dura 

 mater is seen between the separated vertebrae. B.C. 1. 4. M. 7. 



3. 76. Severe Crushing* Fracture of the third and fourth 



Dorsal Vertebrae. — First seven dorsal vertebrae, with the 

 adjacent parts of the ribs — cleaned, dried, and varnished, and 

 the canal exposed by the removal of the laminae on the right 

 side, showing the above condition. 



The patient was a lad, aged seventeen. There was paralysis below 

 the injury, with priapism. He lived twenty-five days. 



The adjacent parts of the third and fourth bodies have been 

 greatly crushed. The remainder of the body of the third, with 

 those of the vertebrae above, have been displaced forwards. 

 The heads of the fourth ribs on both sides, as well as those of the 

 lifth, sixth, and seventh ribs on the right side have been broken. 

 The spine of the first, and the spines and laminae of the second 

 and third vertebrae, have also been fractured. The cord must 

 have been crushed. This has evidently been a case of fracture 

 by forcing the spine forwards.
