Abstract: BACKGROUND: Thorough removal of local necrotic lesions and one-stage use of bone repair materials can significantly promote local bony fusion, avoid recurrence of tuberculosis in the middle and long terms and reconstruct spinal stability in the surgical treatment of spinal tuberculosis.  
OBJECTIVE: To review the application of bone graft materials in the treatment of spinal tuberculosis.
METHODS: The first author searched the articles related to bone graft materials of spinal tuberculosis in Bailian, CNKI, and Natures databases published from 2001 to 2020. The priority was the articles published recently or in authoritative journals. The search keywords were “bone graft materials, bone tissue engineering; spinal tuberculosis; titanium mesh; autogenous bone” in Chinese and English.
RESULTS AND CONCLUSION: At present, bone graft materials have been widely used in clinic, but each has its own disadvantages. For example, the amount of autologous bone is limited, and the transplantation of autologous bone will cause bleeding and potential complications of donor site; allogeneic bone will lead to delayed healing and infection; titanium mesh has the problems of postoperative subsidence and kyphosis correction angle loss; the organic polymer materials such as polylactic acid and polymethyl methacrylate are lack of bone induction performance. Although Ca/P-based ceramic materials can be used as carrier materials of antituberculosis drugs, their biomechanical properties cannot fully meet the clinical needs. In view of the shortcomings of the above materials, it is necessary to find a composite bone tissue engineering material, which can meet the requirements of good biocompatibility, mechanical properties, degradation properties, osteogenic activity, and drug release performance.
