The diabetic foot is "common foot problems in persons with diabetes mellitus, caused by any combination of factors such as diabetic neuropathies; peripheral vascular diseases; and infection. With the loss of sensation and poor circulation, injuries and infections often lead to severe foot ulceration, gangrene and amputation."[1]
Diagnosis
The signs of underlying osteomyelitis are "an ulcer area larger than 2 cm2, a positive probe-to-bone test result, an erythrocyte sedimentation rate of more than 70 mm/h, and an abnormal plain radiograph" according to a systematic review by the Rational Clinical Examination.[2] A normal magnetic resonance imaging makes osteomyelitis unlikely.
The National Institute for Health and Clinical Excellence (NICE) has addressed screening and recommends annually:[3][4]
Physical examination of patients’ feet:
- testing of foot sensation using a 10 g monofilament or vibration
- palpation of foot pulses
- inspection of any foot deformity and footwear
Although NICE and others[5][6] have recommended monofilament testing, its contribution in the major randomized controlled trials is not clear.[7][8]
If screening with the monofilament is done, a three site test of the plantar surfaces of the great toe, the third metatarsal, and the fifth metatarsalsis is adequate according to a systematic review[9] of studies[10]. Another systematic review questions the test accuracy of the monofilament exam.[11]
The role of patient education in preventing ulcers is not clear according to the Cochrane Collaboration. [12]
Prevention
"Of all methods proposed to prevent diabetic foot ulcers, only foot temperature-guided avoidance therapy was found beneficial in RCTs" according to a meta-analysis.[13]
