AbstractDifficult cavity wounds have undermined and tunneling morphology of their edges or a location which is difficult to access. Collagen dressing is an interactive dressing designed for wound management. Collagen particles are designed for cavity wound management. Filling the difficult cavity wound with collagen particles has some practical problems. To overcome these problems we have used an innovative method of filling collagen particles in difficult cavity wound. Innovative method of filling collagen particles is simple and effective solution of the problems faced in managing difficult cavity wounds.
