598 ACCIDENTS INCIDENTAL TO PARTURITION 



and more effective when passed through the skin at the point of the hip. 

 Two wires across are generally sufficient ; the ends are bent round by 

 pliers after they are inserted, and through these eyelets on each side a 

 vertical wire is passed (Fig. 199). This keeps the horizontal wires 

 together, and in place. 



Other metallic sutures, in the form of pins, screwed at one end to fix 

 into plates after being pissed through the labia of the vulva, and other 

 contrivances of this description, have been described ; but in principle 

 they are all the same, and there is no manifest advantage in their 

 employment. 



In fact, it may be said of all the labial or other sutures, that they in no 

 respect prevent the inversion of the organ internally, but merely prevent 

 its escaping beyond the vulva ; and, as their integrity depends not only 

 upon the material of which they are composed, but also upon the integ- 

 rity, or power of resistance of the textures through which they pass,

it often happens that they either give way themselves, or they " tear out " 

 prematurely, leaving oftentimes troublesome wounds or cicatrices. 



It must not be forgotten, too, that even under the most favorable cir- 

 cumstances, these sutures, both during their insertion and their main- 

 tenance, are a source of uneasiness and pain to the animal. 



Bandages^ or Trusses. — To dispense with the inconveniences of the 

 pessary and suture, the bandage or truss has been proposed, and exten- 

 sively employed ; and we must confess that, in the great majority of 

 cases of uterine inversion, it should be adopted in preference to the 

 other methods of retention. 



The truss or bandage may be composed of cords, surcingles, leather, 

 canvas, etc., which are so arranged and disposed as to make pressure
