We offer our personal experience of the use of massive bone allografts after tumour resection. We demonstrate the long-term results from 71 patients (72 allografts) operated on between 1961 and 1990. The long-term survival rate in osteoarticular and intercalary grafts is around 60%. Fractures of the graft can be salvaged in most cases. Infection leads to the removal of the graft in almost all cases. Factors influencing the survival, remodelling and complications of the grafts are discussed. The regime of cryopreservation, fixation and loading of the graft influence these factors, as do the use of autologous bone chips around the allograft-host junction and the application of chemotherapy or radiation. Fracture of the graft can be salvaged in most cases, as opposed to infection which remains the most severe complication and can occur at any time. Even with the improvement of tumour endoprostheses, the use of allografts remains an option, especially in young patients.
我们分享了肿瘤切除术后使用大块骨移植的个人经验。我们展示了1961年至1990年间接受手术的71例患者(72次骨移植)的长期结果。骨关节移植和节段性移植的长期存活率约为60%。在大多数情况下,移植骨骨折可以得到挽救。感染几乎在所有情况下都会导致移植骨被移除。讨论了影响移植骨存活、重塑和并发症的因素。移植骨的冷冻保存、固定和加载方式会影响这些因素,同种异体骨与宿主结合处周围自体骨碎片的使用以及化疗或放疗的应用也会产生影响。与感染不同,移植骨骨折在大多数情况下可以得到挽救,感染仍然是最严重的并发症,并且可能在任何时候发生。即使肿瘤人工关节有所改进,骨移植的使用仍然是一种选择,尤其是在年轻患者中。
