Objective To review the l iterature about the development of resection and reconstruction of sacral tumors. Methods Based on an extensive review of the latest l iterature concerned, we analyzed the cl inical research on resection and reconstruction of the sacral tumor. Results The development of resection and reconstruction of the sacral tumor in the fields of modus operandi and biomechanics provided a new cl inical concept for the therapy of the sacral tumor. Conclusion On the basis of the research of biomechanics, the therapy of the sacral tumor has a bright future.
