Surgical StrategySurgical StrategySurgical ProcedureSurgical Procedure
• Segment spinal instrumentation with Legacy pedicle screw rod construct, thoracic 10 to sacral pelvis. This is ten levels to correct a 50º lumbar curve.
• Micro lateral recess decompression L1-2, L2-3, L3-4, L4-5, L5-S1 on the left; and L4-5 and L5-S1 on the right for spondylolisthesis.
• Posterior spinal fusion using autogenous bone T10 to sacral pelvis • Right iliac crest exposure for the placement of pelvic fixation.• Spinal osteotomy with removal of facets which are ankylosed for
mobilization of lumbar curve L1-2, L2-3, L3-4 bilaterally.• Partial laminectomy for removal ligamentum flavum and mobilization and
lordosis spinal deformity L1-2, L2-3, L3-4, L4-5•• Anterior Anterior interbodyinterbody fusion, L5fusion, L5--S1 using a PEEK 12 mm implant with S1 using a PEEK 12 mm implant with

Reconstruction included the whole curve, and the isthmic spondylolisthesiswith extra fixation including iliac fixation because of the high instabilities and of the long lever arm.
