Saucerization and Arthrodesis

Hello :)

I was fascinated with this two terms :- Saucerization in Osteomyelitis and Arthrodesis (I studied it in treatment of foot drop).

SAUCERIZATION

-Extension of surgical debridement
-Debrided wounds left open widely through excision of overhanging soft tissue and bone
-Wounds drain freely (otherwise If we close it the pus will keep on collecting)
-Abscesses do not form
-Limited to areas where it causes acceptable loss of function e.g. Tibia and femur

Arthrodesis

The term arthrodesis refers to surgical fusion of a joint.
The indications for this are pain & instability in a joint and, in some situations, following the failure of joint replacement.

FIXATION POSITIONS
The optimum positions for arthrodesis in different joints are as follows:

1. SHOULDER:
-In such a position that the hand can comfortably reach the mouth.
-The person will be able to perform the day-to-day activity like eating.combing,scratching the back,cleaning.
-Arthrodesis of shoulder joint is usually reserved for a flail joint as may follow a brachial plexus injury.
-Stabilization of this joint may lead to improvement in the remaining distal function of the arm.

2. ELBOW: 90° of flexion.
(Suppose you won't be able to flex it 90 degree ,then what will happen? Try eating food with that position. You won't be able to do that without this.)

3. WRIST: A few degree of extension
4. THUMB:
-MCP joint in 20° of flexion.
-IP joint in slight flexion.
5.FINGERS:
MCP joints in 20° -30° of flexion.
 (These joints are rarely fused).
 Proximal IP joints in 40° -45° of flexion (less in middle & index fingers)
To show the importance of fixation
