Progress of research and technology application of the treatment of fracture nonunion / 中国组织工程研究

ABSTRACT

BACKGROUND:Nonunion is a common clinical problem of bone fracture. For decades, with the help of internal/external fixation materials, popularization of microsurgical technique, innovation of bone graft materials, especial y molecular biology techniques, breakthrough progress has been made in the treatment of nonunion. OBJECTIVE:To summarize the research progress of treatment in nonunion and to provide better technology theory and choices of method for the treatment of nonunion in future. METHODS:The PubMed database and CNKI database were retrieved by the first author for the articles related to reason and treatment method of nonunion published from January 1990 to May 2013. The key words were “fracture nonunion, treatment, progress”. For the articles in the same field, those published recently or in authorized journals were selected. RESULTS AND CONCLUSION:The repetitive and old articles were eliminated, and final y 48 articles were selected for further analysis. At present, two methods can be used in the treatment of nonunion, including nonsurgical method and surgical method, the surgical method is utilized more frequently and more efficiency in clinic. Fracture healing is the complex process involving various aspects, and once the nonunion occurred, different patients should be treated with different methods, and the combination of various surgical and nonsurgical methods can be used if necessary to obtain satisfactory effect. But al the treatment methods should pay attention to soft tissue protection.
