Collagen matrix wound dressings and the treatment of DFUs.

Objective: To obtain clinical evidence on the use of a collagen wound dressing in patients with diabetic foot ulcers (DFUs). Method: A convenience sample of patients managed in the podiatry outpatient clinic over an 8-month period were included in the evaluation, if their DFUs were not progressing. All participants received traditional adjunctive wound care as part of their treatment. Wound surface-area measurements and imaging of patients was carried out on a regular basis to allow the tracking of wound healing. Results: Six patients, with seven wounds were included in this study. There was an overall decrease in wound surface area over time. Three patients showed a relatively swift reduction in wound area, while one patient showed a slight increase in wound area. The percentage decrease in wound area levelled out quite quickly in three patients, with a mean wound duration of 14 months compared with 7.3 months in the remaining four wounds. One patient died of an unrelated cause. Conclusion: This case ser...
