Surgical intervention and customised dressings in an extremity wound caused by necrotising fasciitis: a case study

Necrotising fasciitis can result in extensive loss of soft tissue and limb function. Therefore, surgical intervention requires a balance between extensive tissue removal and saving the limb. A 56-year-old male presented with necrotising fasciitis of the upper extremity. Debridement resulted in a full-thickness wound of the forearm and upper arm, an exposed olecranon and two proximally-based skin flaps. Reconstruction required multiple debridements to optimise the wound for skin grafting and to obtain flap adherence to underlying tissues of the upper arm. Conventional dressings over the flaps proved unsuccessful. Therefore, a customised versatile dressing to address each area of the wound was developed. Negative pressure wound therapy (NPWT) was applied over the exposed muscle (no exposed bone or tendon) of the lower arm and anterior upper arm; a hydropolymer foam dressing covered the elbow region. Closed incision negative pressure wound therapy (ciNPT) was applied over the incision on the posterior upper arm. Ultimately, complete wound closure was achieved, with normal/near-normal range of motion for all joints of the affected limb. There was complete take of skin grafts on the wrist, lower arm and anterior upper arm. ciNPT was effective in holding the incision together and promoting healing of the posterior upper arm, and the hydropolymer foam dressing aided with healing and coverage of the elbow region. In this case, healing of a large, complex upper extremity wound and restored limb function were achieved following use of a combination of surgical techniques and customisation of wound therapy modalities.
