 "with the soft muscular substance in the center, 



Retraction of the Tibial Aponeurosis. 



What importance is attached to retraction of the tibial apo- 

 nev/rosis ? 

 By some authorities retraction of the tibial aponeurosis 

 is given as the cause of stringhalt. 



Does this assertion prove true 9 



By no means. Some stringy horses make a recovery 

 when section of the aponeurosis is made, especially when

 Sfingbone, spavin, coronary caulking, etc.
