HYGIENE OF THE BONES. 355 



the person should be moved as little as possible. If neces- 

 sary to move the body, care should be taken to keep the limb 

 straight, lest the sharp ends of the bones cut blood tubes and 

 other tissues. It is well to tie some rigid object alongside 

 the broken limb to keep it straight. 



Sprains and dislocations are injuries to the joints, and 

 often bring more serious results than a broken bone. There 

 should usually be complete rest until the part can be used 

 without pain. Otherwise a stiffened joint may result.
