DISLOCATIONS

or a ring in the manger, or over a beam (Plate XLIII, fig. l). This having 

 been done, the hand is placed beneath the bone, which is pressed in an 

 upward and forward direction. If the leg at the same time continues to 

 be forcibly advanced, the patella will soon yield to the pressure, and with 

 a sudden click fall into its place. 



To keep it there is the next requirement, and for this purpose the leg 

 must be made secure to a collar round the neck (Plate XLIII, fig. 2), and 

 the animal tied up to the rack, or put in slings, and kept perfectly quiet.

A sharp blister must then be applied over the region of the stifle, and, 

 in addition, it is recommended that a shoe, thicker at the toe than at the 

 heels, and having a projecting piece of iron attached to the former, be 

 put on. So soon as the effects of the blister have passed away, it may 

 be desirable to repeat it before the animal is relieved of restraint. 



Where the mishap results from general weakness, or slow growth and 

 development of the parts concerned, a liberal supply of good food is of the 

 first importance, and this should be supplemented by sulphate of iron and 

 nux vomica, given alternately night and morning in the corn. 



The patient should be confined to a small shed or loose -box, and 

 blistered over the stifle from time to time, until the displacement ceases 

 to occur.
