<p>In recent years, many books on wound management have used terminology such as 'chronic wound care' or 'chronic wound management' [1-5]. Other descriptors have also appeared in the literature, eg 'problem wound' [6], 'chronic and non-healing wounds' [7], 'non-healing wounds' 8], 'hard-to-heal wounds' [9], 'recalcitrant wounds' [10], ‘difficult’ [11] or ‘complex’ (see above). </p>
