2. Eradication of dead space 
| The cavity remaining
should then be ‘de-roofed’ to such an extent that the tubular
bone is widely opened. One of us even removes enough bone to convert the
remaining bone to resemble a saucer (saucerisation) when this is allowed
by the thickness of the newly formed involucrum. At the proximal and distal
ends this is impossible to do as the shape and texture of the bone in
these regions will not have been adequately increased (in fact ‘strengthened’)
by the disease to allow removal of one half or more of its circumference.
However, one should aim to eradicate as much as possible of any dead space
so that the surrounding soft tissues can fill all the cavity produced.

sequestrectomy and saucerisation - but note the 'man made fracture'
which fortunately healed without trouble |
