‘Of the back never happens without immediate death, the spinal mar- _ 
row being inevitably broken. 
‘At sometimes happens, however, that’ partial dislocations of the 
back take place, and the patient may survive, and even a complete 
cure may be obtained; but this does not often happen. 
These luxations may be known by examination, by the body being 
distorted, and by a paralysis of all that part of the body below it. 
These dislocations are extremely difficult to reduce, because the 
bones are usually forced inward. The safest, and perhaps the most 
certain method is, to bend the body slowly and gradually forward, as 
far as it can be done, over a cask, extending it a little at the same 
time. Tf this brings it into place, the body should be immediately 
raised ; but if not, it should be repeated. hen the displaced bone _ 
is much out of its place, neither this nor any other method will pro- 
bably succeed. aS 7 
DISLOCATIONS OF THE COLLAR BONE, 
Are not common ; they are more liable to be broken. They may — 
be luxated, however, at either end, though usually at its junction with 
the breast bone. - oe ice : 
As the collar bone is thinly covered, dislocations of their ex- 
tremities are easily discovered ; they commonly produce a good 
deal of stiffness and immobility in the shoulder ; for the neck of the 
shoulder-blade, having lost its suppert, is liable to be drawn out of 
its situation. : 
_ A dislocation of this bone is easily reduced by pressure withthe 
fingers. The difficulty consists in keeping it in place.. The weight 
of the fore-arm ought to be moderately supported, and a little press 
sure made upon the displaced end with a bandage, ee
