RESULTING FROM FRACTURE OF THE PELVIS. 123 
fracture is most satisfactorily diagnosed by rectal examina¬ 
tion. Tlie band, in the rectum, easily detects abnormal 
mobility, crepitation and possibly swelling along the shaft 
of the ilium, either by walking the horse or by moving the 
leg otherwise. (See fig. 23.) 
Fig. 23.—Schema illustrating fractures of the pelvis in the horse. 
(1) Fracture of external iliac angle ; (2) internal iliac angle ; (3) shaft of 
the ilium ; (4) transverse portion of the os pubis; (4a) external 
portion of the ischium; (5) cotyloid cavity ; (6) tuber ischii; (7) 
symphysis pubis. 
3.—Fracture Through, the Obturator Foramen. 
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 
.cymptoms of internal hemorrhage, as blanched visible 
mucous membranes, hurried breathing, etc. 
Palpation .—Kectal examination gives positive results as 
to crepitation and location of the fracture. (See fig. 23.)
