Fracture risk assessment in children with benign bone lesions of long bones

Figure 1 Schematic illustration of lesion measurement. The lesion-to-bone width was calculated by the maximum ratio of lesion width (a) to transverse width at the level of the lesion (b). Axial cortical involvement was measured by the largest longitudinal measurement of the entire lesion (c).

Figure 3 Receiver operator characteristic curve when the cutoff is seven. The area under the curve is 0.814, which is the optimal classifier to predict impending pathological fracture. ROC: Receiver operator characteristic.
