Pressure sores: classification and management.
Four grades of pressure can be recognized on the basis of pathophysiology of soft tissue breakdown overlying bony prominences. Management is correlated with the extent of the lesion and ranges from local wound care, turning and systemic support for Grade I and II, to local and radical excision with soft tissue flap closure for the more extensive Grades III and IV.
