We performed biopsies during reoperation for minor complications in two active young patients 9 and 19 months after massive bone allograft implantation for bone tumour. The grafts were dead and resorption-apposition activity, when present, was predominantly in subperiosteal areas. Inflammatory infiltration was very seldom found. Features considered as 'microfractures' or 'microcracks' were noted in the cortical ring together with the formation of woven bone, in areas with remodelling. Such cracks are likely to be of mechanical origin and do not inevitably lead to complications.
我们对两名活跃的年轻患者进行了再次手术活检，这两名患者在因骨肿瘤接受大块骨移植后9个月和19个月出现了轻微并发症。移植骨已坏死，存在的吸收-沉积活动主要位于骨膜下区域。很少发现炎性浸润。在重塑区域的皮质环中发现了被认为是“微骨折”或“微裂纹”的特征以及编织骨的形成。这种裂纹可能源于机械因素，并不一定会导致并发症。
