ATEC’s Calibrate Posterior Straight Expandable (PSX) Interbody System is designed to correct sagittal malalignment by allowing precise surgeon-controlled adjustments to achieve physiological lordosis for each patient. The implant features a low-profile when collapsed, facilitating insertion without compromising sagittal corrective capabilities. Once expanded, the implant conforms to the contour of the endplates, maximizing surface area contact while minimizing point loading.
