Case 1: Lumbar spine anteroposterior and lateral standing radiographic images of the lumbosacral spine demonstrated intact hardware from L4 to S1, evidence of an iatrogenic flat back, grade I spondylolisthesis of L4-L5 level, grade I adjacent segment spondylolisthesis at the L3-L4 level, and increased proximal lumbar lordosis to compensate for her iatrogenic flat back.

Case 1: Lumbar spine magnetic resonance images verified adjacent segment deterioration at the L3-L4 level as well as reduction in the degree of spondylolisthesis in comparison to the standing radiographic images. There was also evidence of central and lateral recess stenosis and a disc herniation at this level.

Case 1: Computed tomography images after stage II confirmed substantial restoration of lordosis and reduction of the spondylolisthesis at both the previously fused L4-L5 level as well as the adjacent L3-L4 level.

Case 1: Postoperative EOS ImagingTM (Electro Optical System) full-length spine radiographs demonstrate reduction of the spondylolisthesis and restoration of spinopelvic and sagittal parameters. PT, sagittal pelvic tilt; PI, pelvic incidence; SS, sacral slope; LL, lumbar lordosis; PI-LL, PI-LL mismatch; TK, thoracic kyphosis; TPA, T1 pelvic angle; SVA, sagittal vertical axis; C7PL, C7 plumb line; MC, major Cobb angle.

Case 2: Preoperative EOS ImagingTM (Electro Optical System) full-length spine films revealed Harrington rod fixation across the thoracolumbar spine with degenerative changes most pronounced from L4 to S1. PT, sagittal pelvic tilt; PI, pelvic incidence; SS, sacral slope; LL, lumbar lordosis; PI-LL, PI-LL mismatch; TK, thoracic kyphosis; TPA, T1 pelvic angle; SVA, sagittal vertical axis; C7PL, C7 plumb line; MC, major Cobb angle.

Case 2: Computed tomography images revealed end-stage deterioration at the L4-L5 and L5-S1 levels, with foraminal stenosis at both those levels. The proximal fusion was well healed with a solid posterior fusion mass.

Case 2: Computed tomography images after stage I anterior fusion.

Case 2: Preoperative planning for robotic-assisted placement of pedicle screws. Note that screws placed through fusion mass where anatomic landmarks are lost.

Case 2: EOS ImagingTM (Electro Optical System) full-length spine radiographic images after stage II posterior reconstruction revealed significant improvement in lumbar lordosis and sagittal parameters. PT, sagittal pelvic tilt; PI, pelvic incidence; SS, sacral slope; LL, lumbar lordosis; PI-LL, PI-LL mismatch; TK, thoracic kyphosis; TPA, T1 pelvic angle; SVA, sagittal vertical axis; C7PL, C7 plumb line; MC, major Cobb angle.

Case 3: Cervical spine anteroposterior and lateral radiographs demonstrate kyphotic sagittal alignment of the cervical spine with a grade II anterolisthesis of C2 on C3, autofusion of C3 and C4, and retrolisthesis of C4 on C5. Prior instrumented fusion of C5-C6 with anterior plating and posterior lateral mass screw that appeared to be intact.

Case 3: Full-spine radiographs demonstrate the patient’s chin-on-chest deformity.

Case 3: Preoperative cervical spine computed tomography images. The images showed loss of disc space height at C6-C7, evidence of laminectomies from C3 to C6, and evidence of autofusion at the C3-C4 level.

Case 3: Postoperative radiographic images show the final construct with pedicle screw fixation and deformity correction.

Case 3: Pre- and postoperative lateral radiographs demonstrate significant improvement in sagittal alignment (normal range for CBVA20.
