Subcutaneous Bursae

HIDE
PrevNext

0:00

<v ->Now, subcutaneous bursae are typically

0:03

synovial-lined flattened sacks that exist

0:06

between the skin and dermis superficially,

0:09

and more deeply between the bone

0:11

and the covering periosteum.

0:14

Small amounts of fluid are often present

0:17

within these subcutaneous bursae,

0:20

and that does not produce symptoms.

0:22

These bursal walls are tethered both to the periosteum

0:26

of the bone and to the dermis,

0:28

and they move with those structures.

0:31

And because of that movement they promote free

0:34

or frictionless movement of the tissues

0:37

in this particular region.

0:39

We often see bursitis in various subcutaneous bursae

0:43

in the human body.

0:45

To give you an example, we'll start here.

0:48

We're looking at a subcutaneous bursa.

0:50

You know it well as the olecranon bursa.

0:53

In this example, this is not a gouty tophus,

0:56

but this is urate material within the bursa.

0:59

Note the abnormal signal:

1:01

Being homogenous of the altered signal

1:04

and the thickened wall

1:06

of this particular subcutaneous bursa.
