Subsidence of LT-CAGE devices at L5–S1. Subsidence of LT-CAGE devices at L5–S1. Sagittal (A) and coronal (B) reformatted CT images demonstrate subsidence of the LT fusion devices (small arrows) through the L5 inferior endplate into the vertebral body in a 60-year-old man. The sagittal image demonstrates new bone formation (large arrow) posterior to the fusion device with bony bridging taking place across the disk space. Alan L. Williams et al.
