Radiographic assessment was made of metastases in 69 consecutive patients with pathologic femoral fractures. The following variables were considered: width of metastasis, ratio between width of metastasis and bone, axial length of cortical destruction, and proportion of cortical bone destroyed of the circumference. Differences in size of the metastases were not related to location in the femur or histologic type. In 62 of 69 fractures the ratio between width of the metastasis and bone was greater than or equal to 0.60, axial cortical destruction in the neck was greater than or equal to 13 mm and in other parts of the femur greater than or equal to 30 mm, and cortical destruction of the circumference greater than or equal to 50 percent. Prophylactic internal fixation need not be considered for femur metastatic lesions that do not reach these limits.
对69例连续性病理性股骨骨折患者的转移灶进行了影像学评估。考虑了以下变量：转移灶宽度、转移灶宽度与骨骼的比例、皮质破坏的轴向长度以及圆周皮质骨破坏的比例。转移灶大小的差异与股骨位置或组织学类型无关。69例骨折中有62例转移灶宽度与骨骼的比例大于或等于0.60，颈部轴向皮质破坏大于或等于13毫米，股骨其他部位大于或等于30毫米，圆周皮质破坏大于或等于50%。对于未达到这些限度的股骨转移病变，无需考虑预防性内固定。
