Researchers examined patients treated with primary posterior instrumentation and arthrodesis and identified subsequent spine surgery and death events. There were no perioperative deaths, spinal cord injuries or acute wound infections among the 117 participating patients.
Among the 12 patients who underwent subsequent spine surgery, the survival rate after five years was 91 percent. Approximately 20 percent of patients died four to 20 years postoperatively. The only variable associated with life survival was perioperative complications, and patients younger than 13 years were more likely to have perioperative complications.
