This book is an interesting and easily readable overview of cutaneous ulcers and pressure sores. Chapters include information on etiology, diagnosis, evaluation, and basic science as well as the history and societal aspect of these difficult problems.
The magnitude of the problem is addressed early:
The estimated cost of healing a pressure sore is between $5000 and $75,000 depending on depth, complications, and treatment.
In addition to pressure sores, there are approximately 12 million people with diabetes in the United States, a considerable portion of whom will develop foot infections or ulcerations that will eventually end in amputation.
