One-Stage Perifascial Areolar Tissue and Skin Grafting Combined with Negative Pressure Wound Therapy for a Refractory Wound with an Exposed Elbow Joint and Extensive Skin Defect

Joint exposure with an extensive skin defect following soft tissue tumor resection might cause a refractory ulcer. Although a vascularized tissue transplant is ideal for ulcer treatment, it is a highly invasive procedure and usually unsuitable for older patients with general prostration. One-stage perifascial areolar tissue (PAT) and skin grafting combined with negative pressure wound therapy (NPWT) is less invasive and effective procedure for refractory wounds with exposed bones and tendons. This is the first case where this procedure was used to treat a wound that involved an exposed elbow joint with an extensive skin defect. An 80-year-old woman underwent wide excision to remove a leiomyosarcoma on the olecranon with reconstruction using an ipsilateral pedicled latissimus dorsi musculocutaneous flap. The distal three-quarter of the flap was necrosed owing to insufficient blood supply. Furthermore, an articular capsule deficit of 1.5 × 1.0 cm2 was found during necrotomy. The PAT was harvested from the lower abdomen as a non-vascularized tissue, and the articular capsule deficit was covered by overlapping on the granulation tissue around the deficit. Simultaneous split-thickness skin grafting combined with NPWT was applied on the PAT and residual skin defect. Wound healing was achieved in 4 weeks postoperatively without synovial fluid leakage. Elbow joint motion ranging from 0 to 120° was maintained 18 months postoperatively. This procedure helped achieve better wound healing and sufficient functional outcome. Furthermore, this can help decrease patients’ burden by preventing invasive resections associated with severe functional impairments or long-term rehabilitation requirements.
