Part of the reason
that we are able to move so freely
is due to the flexibility of our
joints.
Bursas
are small, fluid filled sack-like
structures that serve to diminish
friction between two moving
structures, to allow them to move
over one another with more fluidity.
There are over 150
bursas
throughout your body, found where
tendons meet bones to cushion their
movement and reduce rubbing; if we
didn't have bursas the lack of
lubrication would limit our range of
motion, significantly increase wear
and tear, and be very painful. |

When a bursa is
inflamed it results in a condition
called
bursitis.
This usually occurs with repetitive
use of a joint or constant pressure;
occasionally an infection within the
bursa will be responsible for the
inflammation.
Due to this
inflammatory process, the bursa
loses its lubricating ability,
becoming more swollen, painful and
inflamed as it is moved. Due to its
diminished function, the joint
itself will become painful and hard
to move. Normally, it is the major
joints that are more susceptible to
bursitis such as the knee,
hip or shoulder, but it can also
occur in the smaller joints such as
the big toe. Sometimes, small
calcifications can form on tendons
were they meet joints, causing the
development of new bursas in these
areas.
Symptoms of bursitis
can appear similar to tendonitis or
arthritis and can be mistaken for
these other conditions. Bursitis
is unlike other conditions involving
bones and joints and does not lead
to deformity and is usually short
lived, but can flare up chronically.
Symptoms can be more noticeable at
night or after periods of use.
Similar to other musculoskeletal
conditions, bursitis can be very
painful and limit motion. As stated
earlier, the most common reason for
bursitis is over-use or injury, but
it can also be associated with other
conditions such as arthritis, gout,
bacterial infection, and rarely,
tuberculosis.
There a few
different types of bursitis,
mainly named after the type of
occupation that can cause the
condition:
-
Weaver's bottom.
This type of bursitis gets its
name from an inflamed bursa
resulting from sitting on a hard
surface and swaying back and
forth, such as sitting at a loom.
The bursa affected sits over the
bone in your buttocks.
-
Housemaid's knee.
In this type of bursitis a soft,
egg-shaped bump forms on the front
of your knee, due to kneeling
while scrubbing a floor, gardening
or doing other activities that
place pressure on your knees.
-
Miners' elbow.
This form results from swinging a
pick. You may get a similar
inflammation by pushing a vacuum
cleaner back and forth. Constant
hammering and swinging a tennis
racket are other examples of
repeated physical activities that
may lead to bursitis of the elbow
or shoulder. In addition, repeated
leaning on your elbows could lead
to bursitis over the tip of your
elbow.
-
Dull
ache in your hip, shoulder or
elbow or smaller affect joint
-
Heat
or swelling in area with inflamed
bursa
-
Limited range of motion in
affected joint
-
Pain
and stiffness with movement or
pressure to inflamed bursa
With hip
bursitis,
there will be no noticeable redness
at the hip, due to the fact that the
bursa lies deep to major muscles.
The pain with this type of bursitis
will manifest over the greater trochanter, the part of your
thighbone that juts out just below
your hip.
