REPORTS OF CASES. 
FRACTURE AND DISLOCATION OF THE PATELLA. 
By J. G. Meyer, Jr. 
April 4th I was requested to visit a bay gelding five years old, 
which during a runaway accident on the forenoon of the same day 
received a violent fall upon the hard turnpike, and was dragged a 
short distance by the horse he was hitched with. He sprang to 
his feet without assistance, and though very lame, was led a dis¬ 
tance of one mile and put into a stable, where he broke out into a 
profuse perspiration. He being under considerable excitement 
and in great distress, his owner was prompted to turn him out 
into an adjoining field, where, on my arrival I found him standing 
with the injured right hind limb in a flexed position resting on 
his toe. When forced to move, extreme lameness is exhibited, 
resembling very much that of a case of haemoglobinuria, or what is 
designated as azoturia by some authors, in which the chief sub¬ 
paralytic manifestations are located in one hind extremity only. 
An inspection of the limb reveals the presence of a decided 
swelling and deformity at the stifle joint. An abrasion of the skin 
on the inner side of the stifle joint is visible. Palpation furnishes 
the detection of fluid, either blood or serum, or more probably 
both, within the swelling. An abnormal bony protuberance can 
be easily felt on the outer side and lower border of the femoro 
tibial articulation, which is the external fragment of the fractured 
patella. Its replacement into the trochlea is easily effected by 
applying the hand against the dislodged fragment and pushing 
it gently upwards and inwards, when it will drop into its proper 
position, but as soon as the horse attempts to put any weight
