Conservative treatment, including prolonged, culture-guided parenteral and oral antibiotics, is successful without amputation in a large proportion of diabetic patients admitted for a foot skin ulcer or suspected osteomyelitis. Future studies comparing early amputation with novel therapeutic strategies for severe diabetic foot infection should take into account currently identified factors that predicted failure of conservative treatment on admission to the hospital.

Integration of health promotion in medical education may be needed to increase knowledge as well as attitudes of GPs regarding this issue.

If confirmed in a randomized prospective study, these results indicate that a single bisphosphonate infusion, with consecutive transient improvement of functional capacity in relation to plasma calcium normalization, could help in identifying elderly patients who would benefit by parathyroidectomy.
