LAMENESS IN THE PORE LEG 131 



in the manifestations of discomfort that we may arrive at the 

 proper conclusion. 



Some hyperthermia is to be recognized in acute inflammation, 

 by comparing the extremities. In the fore legs, navicular disease 

 is differentiated by noting absence of contraction at the heel. 

 By use of the hoof testers one may recognize evidence of inflam- 

 mation of the navicular apparatus. In inflannnation of the pos- 

 terior ligaments of the pastern joint, there is also absence of the 

 characteristic stuml)ling which is seen in navicular disease. 



Treatment. — Rest is the first requisite, and in addition every 

 mechanical means possilile to change the center of gravity in 

 the phalangeal region, is to be employed. This is best accom- 

 plished by shortening the toe and paring the sole at the toe as 

 much as conditions will permit. The heel is raised by means 

 of a shoe with moderately high heel calks. 



The iodin-glycerin combination heretofore mentioned may be 

 ai)plied and the parts covered with cotton and bandage. Sub- 

 jects require froin three weeks to several months' rest and must 

 be returned to work carefully, lest the incompletely regenerated 

 tissues suffer injury. 



Regeneration of tissue in such cases, as has been pointed out, 

 is slow and sufficient time for complete recovery must be al- 

 lowed or relapses will occur. 



Fracture of the First 2uid Second Phalanges. 



Etiology and Occurrence. — Fractures of the first phalanx 

 (suffraginis) occur with respect to frequency, second to pelvic 

 fractures. Often, almost insignificant injuries cause phalangeal 

 fractures. On city streets, horses shod with shoes having long 

 calks get caught in frogs of street railways or by slipping on 

 rails, and phalangeal bones are often broken. The author ob- 

 served a case of comminuted fracture of both the first and sec- 

 ond phalanges (suffraginis and corona) in a polo pony caused 

 by making a sudden turn while in action in a contest on the turf. 



Symptomatology. — Fracture of the phalanges is nearly al- 

 ways signalized l)y lameness, and this is marked during the pe- 

 riod of weight bearing. Lameness is usually intense and where
