Bone defects may occur after trauma, infection, or oncologic resection. A critical sized defect is any defect that is unable to spontaneously heal and will require secondary procedure(s) to obtain union. Autologous grafting is widely used, but may be insufficient to obtain union in these situations. Other options include the induced membrane technique, bone transport through distraction osteogenesis, or free vascularized bone transfer. This chapter will review options for obtaining graft, and the aforementioned special techniques for managing these challenging problems.
创伤、感染或肿瘤切除后可能会出现骨缺损。临界大小的骨缺损是指任何无法自行愈合且需要二次手术才能实现骨愈合的缺损。自体骨移植被广泛应用，但在这些情况下可能不足以实现骨愈合。其他选择包括诱导膜技术、通过牵张成骨进行骨运输或游离带血管骨移植。本章将综述获取移植骨的方法，以及上述用于处理这些具有挑战性问题的特殊技术。
