THE
USE
OF LASER
FOR
HAND
SURGERY
Recently, the use of helium-neon
(He-Ne)
laser has
assumed
an impor-
tant role in hand surgery. lts main prop-
erties are:
to
improve body or local mi-
cro-circulation and lymphatic
(white
blood)
return so as
to
reduce swelling,
relieve pain
and
to
manage
inflammation;
to
enhance or balance
metabolism in
the
body;
accelerate
union of
cut surfaces
-
it
seems to work
by accelerating the absorption
of
ne-
crotic (dead) tissues; to stimulate
pe-
ripheral nerve
endings
so as to
stimu-
late (by
reflex)
tissue
re-growth and
repair.
The principle behind such appli-
cations
is
that low-energy
He-Ne laser
actually
have
stimulation
effects, as
against higher-energy ones that
have
destructive etfects. The effect is also
cumulative. He-Ne
laser has
been
found to stimulate biologically antibody
production
and can
affect
body
metabo-
lism at
different
stages.
Such lasers
would also dilate blood vessels and in-
crease DNA. Hence, these properties
are
benelicialto damaged nerves. From
our experience, we believe that the He-
Ne
laser
has an
excellent
prospect
for
hand surgery.
