RESECTION OF FLEXOR PEDIS PERFORANS TENDON.

changes with tincture of iodine. The space is filled with tow, partly 
to check the bleeding which follows removal of the tourniquet, partly to 
restore the fibro-fatty frog and sensitive frog to their normal position. 
Next day the dressing is removed, the wound rinsed out with disin¬ 
fectants, and the dressing renewed, but the cavity is only loosely filled 
with carbolic tow or jute. This second dressing remains in position 
eight to ten days, provided it is not wet through with discharge, and 
neither fever nor severe pain has set in. In the interval the walls of the 
space have everywhere become covered with granulations—in favourable 
cases without any trace of pus formation. The dressing is then renewed 
every four or five days; and as the cavity fills with granulations, less 
material is used. Finally, healing becomes complete ; the frog may 
possibly appear rather shortened, but, as a rule, no other deformity 
remains. The French and German operators often return horses to 
work in four to six weeks, but it is best to keep a protective dressing 
splinted on the sole for some time. 
A very convenient method of applying the above dressings is by 
means of a shoe fitted with a thin iron plate of sufficient size to fill up 
the entire space between the limbs of the shoe, to which it is fastened by 
screws. (See p. 885 of “Horse-shoeing and the Horse’s Foot.”) 
The best results are seen in heavy draught-horses. In carriage and 
trotting horses slight lameness may persist for a considerable time, 
though it seldom proves permanent. (Full clinical details of several 
cases of resection of the flexor pedis tendon are given at p. 451 of 
“ Clinical Veterinary Medicine and Surgery.”) 
Partial resection of the flexor tendon is not to be recommended, 
because the bursa podotrochlearis is generally implicated, and therefore, 
after removal of the necrotic portion, purulent bursitis continues, and 
leads to fresh necrosis of the tendon. For this reason reports of success 
after partial resection of the flexor pedis perforans tendon are to be 
received with caution. The fact that recovery has been described as 
occurring in eight to fourteen days, or even earlier, shows that the cases 
were not cases of necrosis of the flexor tendon, but only of the fibro- 
fatty frog. In these it is often sufficient to freely scarify the parts with 
the curette.

The above injury, as the name implies, is generally produced by the 
animal treading with the heel of one foot on the coronet of another.
