PARALYSIS OF THE HIND LIMB. 



Hollniann saw rupture of the rectus femoris muscle in a cow, followed 

 by permanent lameness ; Eaubner described injuries to the extensors of 

 the patella in a horse. Meyer saw rupture of the rectus femoris, and both 

 vasti muscles in a cow ; a distinct depression could be detected about 

 8 inches above the patella, The symptoms were similar to those of 

 Crural paralysis. 



Rupture of the straight ligaments of the patella has been seen in horses. 

 Mb Her saw two cases of rupture of the external straight ligament — in one 

 due to a collision with a carriage-pole, in the other, apparently to slipping 

 in the stable. Both animals showed inability to bear weight on the limb 

 (supporting leg-lameness). At first the animals could not stand on the

affected limb at all, and later only to a certain extent. Below the stifle 

 only the middle and inner straight ligaments could be felt; in place of 

 the outer was a depression. Pressure at this part caused lively pain. 

 After complete rest for three and four weeks respectively, the horses im- 

 proved sufficiently to return home. 



Voigtlander confirmed his diagnosis of rupture of the straight patellar 

 ligaments in an ox by post-mortem examination. The inability to stand. 

 severe inflammation of the stifle-joint, marked flexion of the limb,, and 

 inability to extend or bear weight on it, and the relaxation of the affected 

 ligaments, left little doubt of the character of the injury, even during life. 

 Voigtlander saw a cow with rupture of the inner and middle straight liga- 

 ments, and of the inner lateral Ligament, and outward luxation of the
