Many in podiatry make wound healing a large part of their practice, while others make all attempts at avoiding this patient population. The reality is that we will all have to deliver some degree of wound care in our practices. The better we understand the biology and biochemistry of the disease process, the better we will be able to deliver appropriate care for these patients. Well respected clinician and educator Jeffrey Niezgoda. MD provides an insightful overview of the many complex aspects of wound care in this presentation. This A-Z lecture is an excellent introduction to the intricacies of wound healing science for the doctor in training. This lecture defines 'compromised wound healing' and then follows with physiology and principles of wound healing and the wound healing phases. The discussion concludes with multiple intriguing case studies and presents treatment options to augment wounds that are granulating. Clearly there is much new in the science of wound healing. Even if your practice is ultimately geared toward sports medicine and elective surgery, you will be faced with problem non healing wounds on occasion. This lecture discusses pressure, arterial, venous, neuropathic, and surgical wound types, which span through all types of practice. Having the basic science understanding and the clinical skills at hand when a problem wound arises will make all the difference for you and your patient's outcome.
