The lumbar spine typically has a slight inward curve known as lordosis. A clinical and radiologic review is presented of a patient who underwent rigid fixation with L4-5 interbody fusion and L3-4 posterolateral dynamic stabilization with Zimmer Dynamic-to-Optima (DTO) hybrid fusion to non-fusion system (Zimmer Spine, Minneapolis, MN) with hydroxyapatite coated pedicle screws that exhibited lucency on radiographic studies which subsequently disappeared. However, there are many disease entities that can cause osteopenia, so the mere finding of radiolucent bone does not mak… All registration fields are required. As most of benign tumors of the osseous spine are asymptomatic, their real incidence is unknown.
