Table 1.
Structural properties (spring stiffness, K, and ultimate forces, FU) predicted from the vertebral models with and without simulated lytic lesions. Simulated lytic lesions grouped based on their sizes, and location (C: centre, LR: lateral right, LL: lateral left, P: posterior, and A: anterior).
