fraccare is most satisfactorily diagnosed by rectal examiua- 

 tion. The liand, in the rectum, easily detects abnormal 

 mobility, crepitation and possibly swelling along the shaft 

 of the ilinm, either by walking the horse or by moving the 

 leg otherwise. (See fig. 23.)

Inspection. — Supporting-leg lameness. Usually no exter- 

 nal deformity, but now and then one sees an oedematous 

 swelling about the scrotum, udder, or belly, together with 

 symptoms of internal hemorrhage, as blanched visible 

 mucous membranes, hurried breathing, etc. 



Palpation. — Rectal examination gives positive results as 

 to crepitation and location of the fracture. (See fig. 23.)
