Abstract:
BACKGROUND: With the constant development of current society, traumatic bone injury caused by the traffic and other accidents becomes more and more common. Bone defect scope is increasingly extend, and the treatment results in the long cycle, the high cost, and the uncontrolled effect, accompanied with infections, bone nonunion and other complications, which not only causes the painfulness of the patient physically and mentally, but also is a difficult problem and challenge for orthopedic surgeons at the same time. OBJECTIVE: To analyze the advantages and disadvantages of traditional treatments and their latest progress, and focus on the research progress and advantages of tissue engineering technology in treating bone defect. METHODS: The author took “bone defect, bone transplantation, tissue engineering, induced membrane technology, bone transfer technology, endothelial progenitor cells, 3 D printing technology” as the key words, and data were summarized by searching CNKI, Wanfang and Pub Med databases. Totally 120 related literatures were retrieved. Through reading the title, abstract and part of the literature content, the outdated, ambiguous and repetitive literatures were excluded. Finally, 49 literatures meeting the inclusion criteria were selected for review. RESULTS AND CONCLUSION:(1) Traditional bone defect treatment has certain defects. The emergence of bone tissue engineering technology is expected to become one of the most effective ways for bone defect.(2) Seed cells have good osteogenic properties and can secrete some important factors.(3) Scaffold material can provide mechanical strength for patients in early stage, and has advantages of good biocompatibility, bone induction, and controllable degradation.(4) The urgent problem of vascularization is also being solved gradually, which can bring good news to the patients with bone defect.
