(A) Paraplegic patient with sacrococcygeal pressure ulcer, underwent excision and gluteus maximus myocutaneous flap closure. Healing was complicated by dehiscence of wound because of malnutrition. The wound was characterised by extensive undermining (B). NPWT was applied for 4 months, allowing for complete obliteration of undermined area. (C) After 4 months, a small persistent wound still remains, but no further undermining was present, and local wound care was continued to full healing.
