Healing does not take place until the sequestrum is extruded or removed by operation.
If the sequestrum be not loose we must wait until it is movable.
Usually running down to the sequestrum, are enormous sinuses, from which comes a foul, purulent discharge.
A mass of dead tissue in a soft part is termed a slough, while the same in bone is called a sequestrum.
In fact, there is less danger in leaving the sequestrum than in attempting to remove it.
The sequestrum is slowly thrown off, and when separated is circular like a coin and presents worm-eaten edges.
The bone is replaced by granulation tissue, and disappears, or part of it may become sclerosed and in time form a sequestrum.
The swelling gradually softens and ulcerates, and a sequestrum may separate and leave a perforation in the palate (Fig. 246).
In some cases a sequestrum is formed, either on the surface or in the interior of a vertebra.
Sometimes the separated and displaced epiphysis dies and constitutes a sequestrum.
