Overview
There are several types
of wound which characteristically are much more
difficult to heal than the acute traumatic wounds.
The major reasons are the typical presence of impaired
perfusion as seen, e.g. with venous hypertension or
diabetes and an underlying disorder such as immobility
as seen in the population with pressure ulcers.
Typically these wounds begin healing by the normal
acute healing process with the process simply
being prolonged into months instead of weeks. There
is also an increased risk of wound complications due
to the underlying impediments to healing. These
wounds are also at high risk for evolving into a
chronic wound where the acute healing process
essentially stops. The three most common types of
wound which fit into the difficult to heal category
are a diabetic, venous stasis and pressure ulcer.
