The researchers examined 126 patients who underwent three-column osteotomy/vertebral column resection and followed them for a minimum of five years. They found:
• Sagittal alignment improved at all postoperative time points from the baseline but diminished from six weeks to five years
• Cornal alignment improved from baseline at six weeks and five years with no deterioration between six weeks and five years
• 36 percent of the patients reported major complications
• 28 percent of the patients had repeat surgery
• ODI and SRS domain scores significantly improved at each time point
• Average outcome scores at five years exceeded all minimal clinically important difference thresholds except the SRS function domain
• Patients reporting major surgical complications showed similar outcomes improvement to those who did not report complications or reoperation
“This demonstrates the durability of these complex spinal reconstructions, even surprisingly in those patients having major complications and/or revision surgery,” the researchers concluded.
