Evaluation of Clinical Outcomes of Negative-Pressure Wound Therapy in Gustilo-Anderson Type IIIA/IIIB Open Fractures...

Background Open fractures are common and serious injuries that primarily affect young males. Fracture management has improved in the last decade. However, infections with their complications are still a concern, especially in open fractures for primary closure of the injured area. A newer technique called vacuum-assisted therapy has become a therapy of choice for many orthopedic surgeons. This study aimed to determine whether vacuum-assisted closure reduces the duration of wound healing and the frequency of infections after fixation of Gustilo-Anderson Type IIIA/IIIB fractures of the extremities. Methodology An observational analytical study was conducted among 34 patients with Gustilo-Anderson Type IIIA/IIIB fractures of the limbs who presented to the Department of Orthopaedics, R. L. Jalappa Hospital, Kolar, from December 2019 to July 2021. Negative-pressure wound therapy was employed for wound closure after fixation of fractures. Patients were followed up for one month. Results The mean age of the patients was 37.06 ± 10.340 years. The prevalence of infection before vacuum-assisted closure dressing was 80.6%, and the prevalence of infection after vacuum-assisted closure dressing was 19.4%. The difference in proportion before versus after the intervention was statistically significant (p < 0.001) according to the McNemar Test. Hence, vacuum-assisted closure dressing decreased the rate of infection. The mean dimension of the wound before vacuum-assisted closure therapy was 66.05 cm² and the mean dimension of the wound after vacuum-assisted closure therapy was 27.97 cm². The difference in the mean before and after the intervention was statistically significant according to the paired t-test (p < 0.001). Hence, vacuum-assisted closure dressing helped decrease the wound size which was proven statistically. Conclusions Vacuum-assisted closure is a viable and beneficial treatment option for complicated fractures with large soft-tissue abnormalities.
