122 PAETICULAR FRACTURES. 



say that in this fracture the legs bent under the horse, and that 

 this was its diagnostic sign. 



Treatment. — Slinging and rest; and as a rule cases terminate 

 very satisfactorily, all that remains being the flatness of the 

 quarter. 



The Coccygeal Bones are also liable to fracture, which may 

 be detected by inability on the part of the patient to raise the 

 tail, difficulty in defsecation, and by crepitation. 



Treatment. — Strong leather binding laced around the taU, ex- 

 tending from its upper to its lower part, proper padding being 

 at the same time used to prevent excoriation. 



The rudimentary spines of the false vertebrae of the tail are 

 sometimes fractured, giving rise to troublesome sinuses. 



The wounds to be laid open, and the detached bones removed. 



A comminuted fracture of the bones of the tail, with violent 

 bruising of the soft parts, succeeded by inflammation, and even 

 gangrene, is occasionally seen in practice. In such, amputation 

 of the tail and removal of all the fractured bones must at once 

 be resorted to, or serious consequences may result, such as 

 irritative fever or tetanus. 



FRACTURE OF THE PELVIC BONES 



May be arranged under seven heads : — 



1st. Fracture of anterior iliac spine, 



2d. „ of posterior iliac spine. 



Zd. „ of the shaft of the ilium. 



4:th. „ through the acetabulum. 



bth. „ into the foramen ovale. 



6^A. „ through the symphysis pubis. 



1th. „ of the tuberosity of the ischium. 



Fracture of Anterior Iliac Spine. — This is the most common 

 form of fracture to which the horse and the cow are liable ; it is 

 generally caused by falls, or by the animal striking this part 

 against a waU or side of a doorway, most commonly the latter, 

 and chipping off, as it were, more or less of this prominent part 

 of the quarter. It is not always attended by lameness, and is 

 distinguishable by lateral flatness of that quarter. 



The broken piece of bone is drawn inwards and downwards
