Is there an easier way to autograft skin in chronic leg ulcers? 'Minced micrografts', a new technique

Background Chronic venous leg ulcers represent an urgent and increasing problem for public health. The use of skin autografts results in a greater therapeutic success in healing chronic ulcers. Objective A simple method of skin autografting that could permit a wider use of skin grafts in outpatients is needed. A new technique allowing skin autografting in a simple one-step process, without complex surgical procedures or expensive technical supplies, is presented. Methods A small, full-thickness skin specimen taken from the patient is finely minced and spread on his leg ulcer bed allowing to cover a surface many times wider than the sample itself. Results This method induces faster re-epithelization of chronic leg ulcers that failed to heal despite good conservative local therapy and give the possibility to repair very large ulcers with small fragments of skin. A clinical case is shown as an example out of 20 ulcers we recently treated. Conclusion Our preliminary report shows that this technique results in a greater therapeutic success (18 of 20 cases) in healing chronic leg ulcers, a common pathology that often affects outpatients treated for very long periods at home or in the Dermatologist's office. In our experience, this new and successful reparative possibility makes ‘mince grafting’ a recommendable procedure.
