The document discusses risk factors, evaluation, and management of diabetic foot ulcers. Key risk factors include neuropathy, peripheral arterial disease, abnormal foot biomechanics, and delayed wound healing. Evaluation involves medical history, physical exam, and lab tests. Management consists of wound debridement, dressing, antibiotics, revascularization if needed, and sometimes amputation for infected or non-healing ulcers. Patient education and preventative foot care are also important.
