The Diabetic Sensorimotor Polyneuropathy (DSPN) is a symmetrical, length-dependent sensorimotor polyneuropathy attributable to metabolic and microvessel alterations as a result of chronic hyperglycemia exposure (diabetes) and cardiovascular risk covariates.
The levels in this new diabetic retinopathy disease severity scale consist of five scales with increasing risks of retinopathy.
Wagner Classification of Diabetic Foot Ulcers
Grade 0: No ulcer in a high risk foot.
Grade 1: Superficial ulcer involving the full skin thickness but not underlying tissues.
Grade 2: Deep ulcer, penetrating down to ligaments and muscle, but no bone involvement or abscess formation.
Grade 3: Deep ulcer with cellulitis or abscess formation, often with osteomyelitis.
Grade 4: Localized gangrene.
Grade 5: Extensive gangrene involving the whole foot.
