486 DISLOCATION OF BONES. 



sively applied. In Blount's Farriery there is a plate repre- 

 senting some ingenious machinery for the cure of these 

 lesions. Mr. Bass, near Barnet, is said to have had several 

 of such cases, which have terminated successfully, by the 

 application of proper splints with bandages ; of which in- 

 stances are now so common, that no practitioner would be 

 warranted in condemning a horse with a simple fracture of 

 one of these bones. 



Fi'actures of the large and lesser Pastern and Coffin Bones. 

 — These bones have never been successfully united. The 

 animal may afterwards, however, be fit for breeding, but 

 never again, or so rarely that the exception proves the 

 rule, can be fit for fast work. When it is determined to 

 try chances, it is better to sling the horse, and allow nature 

 to do the rest. 



Fractured Navicular Bone. — This accident, though rare, 

 never happens unless the bone be much absorbed, and very 

 hollo Wj in consequence of pre-existing navicularthritis. It 

 is impossible to suggest any remedy, or if any measure 

 likely to benefit the part could be thought of, we do not 

 see in what way it is to be applied. 



A Fracture of the prominent portion of the Ilium, or 

 Haunch Bone, sometimes occurs ; when it is of the simple 

 kind, the adhesive inflammation which follows readily unites 

 the parts ; but from the action of the muscular fibres im- 

 planted into the disunited portion, it is drawn aside, and 

 no surgical efforts can retain it in just opposition with its 

 fellow portion. These cases are called hipped, or let down 

 on the hip. 



The Patella is likewise occasionally fractured by violent 

 kicks ; when the action of the tendons inserted into its sur- 

 faces disunites the fractured portions, beyond the power of 

 veterinary surgery to bring them together ; the limb is use- 

 less, having lost the antagonism to undue flexion : it will be 

 therefore of no avail to attempt a fruitless course of hope- 

 less treatment. 



DISLOCATION OF BONES. 



The articular surfaces of bones are sometimes displaced 

 from their proper situation, when they are said to be dis- 

 located or luxated. In human surgery this forms a very
