- Abstract: BACKGROUND:As the population ages at an accelerated rate in China,the incidence of bone and soft tissue infections is likewise on the rise.Bone and soft tissue infections can involve all bone and surrounding soft tissues,including the periosteum,cortex,cancellous bone and bone marrow.Examples of such infections include diabetes foot,osteomyelitis,surgical incision infection,and infection around joint prostheses.Owing to the intricate pathogenesis and challenging treatment,it has become increasingly noteworthy in clinical settings.Negative pressure wound therapy is a modern wound treatment which has been gaining popularity,especially in the area of bone and soft tissue infection. OBJECTIVE:To analyze the global research progress in the utilization of negative pressure wound therapy for treating bone and soft tissue infection in recent years. METHODS:Relevant articles in Chinese and English published in PubMed,Web of Science,and CNKI from 1990 to 2022 were retrieved.Search terms were"negative pressure wound therapy,vacuum assisted closure,negative pressure,osteomyelitis,bone infection"in English and Chinese,separately.A total of 711 articles were initially retrieved,out of which 65 articles were included for further review. RESULTS AND CONCLUSION:Negative pressure wound therapy,as an auxiliary approach to treating wounds,has a range of positive effects such as stabilizing wounds,diminishing edema,decreasing bacterial load,encouraging granulation tissue and angiogenesis,enhancing tissue perfusion,modulating peripheral nerves,modulating biological immunity and promoting the growth and differentiation of osteoblasts.This is a more effective method for managing complex wounds,such as bone and soft tissue infections,than traditional dressings with one-dimensional benefits.Numerous studies,both basic and clinical,have demonstrated the safety and efficacy of negative pressure wound therapy in the auxiliary treatment of bone and soft tissue infections.
