A dual-site trauma system during COVID-19 pandemic - Our experience in a high-risk area with 60-day mortality report.

AIM: We set up a COVID-free trauma site due to the high rates of COVID-19 infections within our hospital. We aimed to determine the incidence of post-operative COVID-19 infection within the first two weeks post-treatment at the COVID-free site and the postoperative mortality rate. We analysed data for non-hip fracture and fragility hip fracture patients separately. METHOD: Data was collected for 138 patients presented during the study period, having 147 operations in total. 103 were non-hip fracture patients and 35 were hip fracture patients. RESULTS: All patients were followed up and none of the non-hip fracture cohort developed symptoms of COVID-19 infection. Postoperative 60-day mortality rate for this cohort was 0.97%. Of the 35 hip fracture patients, none were tested positive for COVID-19. However, two patients were treated as suspected COVID cases due to their symptoms. CONCLUSION: Establishing a separate site with screening for COVID-19 infection can allow safe emergency surgery.

Negative pressure wound therapy - a review of its uses in orthopaedic trauma.

The use of Negative Pressure Wound Therapy (NPWT) for complex and large wounds has increased in popularity over the past decade. Modern NPWT systems consisting of an open pore foam sponge, adhesive dressing and a vacuum pump producing negative pressure have been used as an adjunct to surgical debridement to treat tissue defects around open fractures and chronic, contaminated wounds. Other uses include supporting skin grafts and protecting wounds at risk of breaking down. This review outlines the current and emerging indications for negative pressure wound therapy in Orthopaedic trauma and the existing preclinical and clinical evidence base for its use.
