Direct Impaction and Post Operative

<v ->The third mechanism for septic arthritis

0:03

is direct implantation of organisms into the joint,

0:10

and this can relate to inoculation during joint aspiration,

0:14

joint arthography or arthroscopy, or a penetrating wound.

0:18

I showed you this picture in an earlier lecture.

0:21

This is the human bite with the classic involvement

0:25

typically of the third metacarpal phalangeal joints,

0:28

sometimes of the second,

0:30

and here is the MR evidence in a different patient

0:33

showing you septic arthritis and osteomyelitis.

0:38

And then finally the fourth mechanism is postoperative,

0:41

and although it's not really a separate mechanism

0:45

it relates to one of the others that I have indicated.

0:48

It is well known and it is a serious concern

0:53

for the orthopedic surgeon.

0:55

So, this can occur with a variety of surgical procedures.

0:59

I show you an example here of intramedullary rodding.

1:03

The rod has been removed,

1:05

but what has occurred is a septic arthritis

1:07

and osteomyelitis related to postoperative change.
