Tuberculosis with Tenosynovitis and Septic Flexor Tenosynovitis

HIDE

0:00

<v ->Here's another example of rice bodies.

0:03

This one related to tuberculosis involving here

0:07

an extensor tendon sheath about the ankle.

0:11

And once again, as you look at the gadolinium

0:13

these are not enhancing in the gadolinium image

0:17

but a beautiful example of what rice bodies look like.

0:22

Now, infection certainly can involve

0:24

the flexor tendon sheets of the fingers.

0:26

And we talked a bit about their anatomy,

0:29

the connections to the ulna and radial bursa

0:33

in the first and fifth fingers

0:35

and the absence of those connections

0:37

in the second third and fourth.

0:39

Here's an example of septic flexor tenosynovitis.

0:44

And I wanna indicate to you why this is a serious condition.

0:47

If we just look at the anatomy,

0:49

this is a sagittal section.

0:51

Here we can see the tendon withdrawn.

0:54

This is the tendon sheet.

0:56

If you neglect infective tenosynovitis,

1:00

it will invade the bone producing an osteomyelitis.

1:04

It may invade the joint,

1:06

here the metacarpophalangeal joint

1:08

producing a septic arthritis and it may extend to,

1:12

remember one of those spaces was the midpalmar space.

1:16

So these infections beginning in a tendon sheet

1:19

may extend to other tissues.
