BACKGROUNDChronic ulcers are defined as a slow or non-healing breakdown of epidermal and dermal tissue that lasts more than 6 weeks. Regardless of aetiology, chronic ulcers cause considerable and prolonged distress for patients. The use of newer dressings with collagen dressing may increase the wound-healing potentials.The aim of this study is to compare the efficacy of collagen dressing with that of conventional dressing in the management of chronic ulcers and their healing process.
