Sagittal reconstruction at four months postoperative, from a patient with a two-level, stand-alone instrumented intervertebral lordotic angle, showing five bridges (note there is a propensity for focalized artifact [black spot] between fenestrations in the endplate component, but no lysis about the endplate-implant interface). This image also demonstrates 75% sagittal fill at L4/5 and 100% sagittal fill and L5/1 with 5 bony bridges.
