through the skin and aponcurotic portion of
the pectoralis transversus and panniculus muscles, about 1 to 3 inches
(depending on the size of the horse) below the internal condyle of the
humerus, and immediately behind the ridge formed by the radius. This
latter, and the nerve which can be felt passing over the elbow-joint, form
the chief landmarks. The haemorrhage which ensues is principally venous, and
is easily controlled by the artery forceps. In some cases I have found it
of advantage to put on a tourniquet below the seat of operation, but this
is not always advisable, as it distends the radial artery. We now have
exposed to view the glistening white fascia of the arm, which must be
incised cautiously for about an inch. This will reveal the median nerve
itself situated upon the red fibres of the flexor metacarpi internus
muscle. If not fortunate enough to have cut immediately over the nerve, it
can be readily felt with the finger between the belly of the flexor muscle
and the radius.'[A]

The nerve exposed, the remainder of the operation is exactly as that
described in removing the portion of the nerve in the plantar operation.
The wound is sutured and suitably dressed, and a fair amount of exercise
afterwards allowed the patient.

F. LENGTH OF REST AFTER NEURECTOMY.

This is placed by the majority of surgeons at about three weeks to a
month. Within that period no excessive exertion should be undergone by
the patient. A certain amount of quiet exercise, however, is beneficial,
facilitating the healing of the wounds, and accustoming the animal to the
altered condition of his limb.

G. SEQUELAE OF NEURECTOMY.

These we shall relate collectively, making no distinction between those
following excision of the plantar nerve and those succeeding section of the
median. It must be remembered by the surgeon, however, that the unfortunate
sequelae we are now about to describe are likely to be far more grave when
following section of the larger nerve.

_Liability of Pricked Foot going undetected_.--On account of the warning
they convey to the surgeon, first place among the sequelae of neurectomy
must be given to accidents following loss of sensation. Take, for example,
punctured foot. In any case, in the sense of being unforeseen, it is
accidental. In the neurectomized foot it becomes doubly accidental, in that
not only is it unfor
