Fig. 1-A Anteroposterior radiograph showing a metastatic humeral lesion. The lesion is characterized as diaphyseal and having a midshaft location, a size of >2/3 of the diameter of the bone, and evidence of a cortical breach (in the lateral cortex). The lesion was assigned a Mirels score of 10. Fig. 1-B Anteroposterior radiograph showing progression of the lesion, with increased size and greater cortical disruption. Fig. 1-C Anteroposterior radiograph showing a pathological fracture involving the lesion.
