Use of collagen and negative pressure wound therapy on a diabetic foot ulcer: a case study.

This case study describes the combined use of a wound contact layer dressing containing collagen with negative pressure wound therapy (NPWT) on a diabetic foot ulcer (DFU). The patient was treated at a university hospital in Santiago, Chile. A wound size reduction of 58% was observed within the first 10 weeks of treatment, and the wound went on to heal fully over the next 14 weeks. The combined use of collagen and NPWT helped to initiate healing and prevent amputation of the foot. At 64, the patient was able to maintain his independence and quality of life.
