74 Injuries of Bone. 



downwards and forwards, and the spinal cord and accom 

 panying nerves have been crushed between the body of the 

 tenth and the lamina of the ninth vertebrae. G. C. 2903. 



Presented by John Duncan, F.R.C.S.E. 



3. 82. Fracture throug-h the tenth Dorsal Vertebra in an 



Old Man. — Portion of the ninth and the tenth, eleventh, and 

 twelfth dorsal and first lumbar vertebrae — the muscles cleaned 

 off, dried and partly varnished, to show the above condition. 



The spine had previously been anchylosed, and therefore 

 would not bend. The fracture has passed irregularly through 

 the body, lamina, and spinous processes. The bony masses 

 which had produced the previous anchylosis are seen on either 

 side of the front of the bodies {Arthritis deformans).

3. 83. Dislocation forwards of the tenth, and Fracture of 

 the Body of the eleventh Dorsal Vertebrae.— Section 



through the bodies and laminae of the lower part of the sixth 

 and of the seventh, eighth, ninth, and tenth, and part of the 

 eleventh dorsal vertebrae, to show the canal from the front. 

 The muscles are dissected off — in spirit. 



The body of the tenth vertebra has been displaced for- 

 wards and downwards, and has crushed a fragment from the 

 upper and back part of the eleventh vertebra back iipon the 

 spinal cord, so as to bruise and compress it. An irregular 

 fracture is seen running through the body of the eleventh 

 vertebra. 



This specimen was used by Sir Charles Bell as an argument 

 for the uselessness of trephining the spine after injury.
