What happens when the joints are broken
cracking your knuckles is an
extremely
common habit
most people consider it rude and
still
others believe that the practice is
harmful for your joints so what's
the
truth is this an innocent nervous
tic or
the beginning of arthritis today
we're
answering the question what happens
when
you crack your fingers cracking
joints
isn't interesting and poorly
understood
phenomenon there are many theories
as to
why joints crack or pop but there
is
some contention as to what is actually
happening in your body as a rule
painless cracking of joints is not
harmful however common sense would
generally suggest that the
intentional
and repetitive cracking of one's
joints
is not only potentially bothersome
socially but could also be
physically
troublesome when it produces pain
however knuckle cracking has not
been
shown to be harmful or beneficial
more specifically knuckle cracking
does
not cause arthritis the noise of
cracking or popping in our joints
is
actually nitrogen bubbles bursting
in
our synovial fluid says dr. Robert
clapper co-director of the joint
replacement program according to dr.
Klapper
synovial fluid lubricate your
joints
like motor oil in a car's engine
reducing friction and preserving
our
cartilage the nitrogen bubbles
within
the synovial fluid usually take 20
minutes to reform in your joints
before
they can crack again part of the
appeal
of knuckle cracking could be that
20-minute
lull when gas bubbles are
reforming in the synovial fluid
you might feel looser during that
period
as if you've relieved pressure from
your
joints but the satisfaction is
mostly in
your head feeling good after
cracking
your knuckles is a psychological
experience says dr. Klapper one of
the
most convincing bits of evidence
suggesting that knuckle cracking as
harmless comes from a California
physician who reported on an
experiment
he conducted on himself over his
lifetime he regularly cracked the
knuckles of only one hand he
checked
x-rays on himself after decades of
this
behavior and found no difference in
arthritis between his hands a
larger
study came to the same conclusion
the
other reason that joins seemed to crack
is because our ligaments snap into
place
as we move our bodies
furthermore the nitrogen buildup
theory
has been debunked in recent years
in a
2015 study
researchers watched knuckles
while they were cracked using an
MRI
they found that a cavity formed due
to
the negative pressure created when
the
joint was pulled apart quickly they
determined that the sound was made
by
the formation of the cavity
however this couldn't explain the
loudness of the sound a 2018 study
suggested that the sound was
actually
caused by their partial collapse of
the
cavity a review of studies noted
that it
takes 20 minutes for the cavities
of
fully claps so a new cavity could
be
formed this may be why after you've
cracked your knuckles you're not
able to
do it again right away
there are rare medical reports of
problems associated with this
behavior
that may relate to how much force
is
applied and ones particular
technique
for example joint dislocations and
tendon injuries have been described
after attempts to crack knuckles
one
study published in 1990 found that
among
74 people
who regularly crack their
knuckles their average grip
strength was
lower and there were more instances
of
hand swelling than among 226 people
who
did not crack their knuckles
however the incidence of arthritis
was
the same in both groups so what's
the
verdict cracking your knuckles has
no
inherently harmful or beneficial
quality
it won't cause arthritis or any
other
chronic issues so long as you don't
use
excessive force if you are too
forceful
you may cause pain and inflammation
of
the knuckles if you notice your
joints
are painful or swollen while
cracking
your knuckles it's likely due to an
underlying condition and should be
evaluated by your doctor in case
we're
trying to quit the habit doctors
recommend deep breathing meditation
and
yoga to keep your mind off your
knuckles
