FEACTUEE OF THE INNER MALLEOLUS. 



This consists in fracture of the bony prominence on the 

 inner side of the hock at its highest point. It usually re- 

 sults from a blow with the opposite foot in fighting flies. 

 There is more or less swelhng of the part, with an un- 

 natural mobihty of the process and in some cases dis- 

 tinct grating. It is not unfrequent to have a wound in the 

 skin and a flow of glairy synovia from the opened joint. 

 In other cases, independently of fracture, there is inflam- 

 mation and enlargment of the bony eminence. 



Treatment. Eest is imperative, as the fracture often 

 imphcates the joint. If synovia escapes use a sugar of 

 lead lotion (1 oz. to 1 pt. water and 60 drops carbolic 

 acid), or even apply a blister around the joint, leaving the 

 space of an inch around the wound untouched. In other 

 cases rely on soothiag applications, followed by bhstera 

 when heat is diminished. Such cases usually do well, even 

 an open joint being harmless from the wound being at its 

 upper part. Even pieces of bone may be taken out with 

 portions of the joint surface and yet a satisfactory recovery 

 ensue. 



FRAOTUBE OF THE POINT OF THE HOCK. 



This may merely implicate the extreme summit of the 

 bone in young horses or it may occur lower down in the 

 middle of the bony process. There is much lameness and 

 difficulty in bringing the foot to the ground, the limb being 

 often kept raised and semi-flexed, and the detached por- 

 tion may be felt in front of the point of the hock, or a line 

 of tenderness may be detected across the middle of that 

 bone, detachment and grating being obviated by the strong 

 fibrous investment. 



Treatment. If a portion has been detached from the 

 eammit, place in slings, extend the joint and replace it,
