Initial diagnosis of<unk> s is made primarily via thorough history and physical to include visual inspection of the feet, evaluation of any wounds, distal pulses, and neurologic function. History and physical History should be taken for known recent foot trauma, and the lower extremities should be inspected for signs of recent trauma, including redness, induration, edema, visible ulceration with exudate or pus, or bony deformity. Ulcers do occur in the absence of pathological<unk> . Diagnosis of an infected wound is classically made with ≥2 signs of inflammation or purulence. Peripheral pulses should also be evaluated (posterior tibial and dorsal pedis), and if not palpable, should be further evaluated using ultrasound. In patients with non-palpable pulses, evaluation of PAD with an ankle-brachial index should also be performed. Ulceration or deeper wounds should be probed to identify the depth of penetration and determine involvement of bone, which would indicate osteomyelitis. Neurologic testing includes testing peripheral sensation to vibratory stimuli, temperature, pain, along with deep tendon reflexes. Imaging Imaging may also be used for further evaluation. Plain x-ray, the most common initial imaging study, may show fractures, osteomyelitis, gas collection from gas-producing infective organisms, calcification of blood vessels, or foreign bodies. Magnetic resonance imaging is useful to determine the depth of soft tissue<unk>  and evaluate for presence of osteomyelitis, especially in patients which do not respond to initial antibiotic therapy. Finally, patency of the lower extremity vasculature may be evaluated by magnetic resonance angiography or ultrasonography
