The document discusses the diabetic foot and ankle. It notes that diabetes requires treatment from a multidisciplinary team, with vascular disease often requiring input from vascular surgeons. The orthopedic surgeon sees increasing cases of ulceration, deformity, osteomyelitis, and Charcot osteoarthropathy as direct complications of diabetes. The key topics covered are the pathophysiology of hyperglycemia on tissues, assessment of diabetic foot pathology, management of foot/ankle ulceration and Charcot disease, and treatment of ankle fractures in diabetics. Early diagnosis and a multidisciplinary approach are important to prevent complications.
