Objective: To evaluate the efficacy of low-intensity laser irradiation for the induction of wound healing of a diabetic neuropathic foot ulcer. Case: We report a case of a man with insulin-dependent diabetes mellitus, sensory neuropathy, macroangiopathy and microangiopathy who had been suffering from an ulcer of his first left toe accompanied by osteomyelitis for 6 weeks. Results: After a total of 16 sessions of low-intensity laser therapy using a 670-nm diode laser administered within a 4-week period the ulcer healed completely. During a follow-up period of 9 months, there was no recurrence of the ulcer even though the patient’s metabolic condition remained unstable. Conclusions: Although laser therapy was not applied as a monotherapy, the present observation suggests that it might constitute a useful side-effect-free alternative treatment modality for the induction of wound healing of neuropathic ulcers in diabetic patients. Therefore large properly controlled randomized studies seem justified.
