Diabetes mellitus affects around 10% of the whole population and unhealed diabetic foot ulcer is one of the most debilitating and economically burdensome conditions. This condition is commonly seen by different specialists including physicians, orthopaedic surgeons and vascular surgeons.

We also review the literature with respect to management strategy and rationale of hyperbaric oxygen therapy for diabetic foot ulcers.
