The researchers examined posterior-only surgical procedures for AIS from 2007 to 2008 and followed patients for a minimum of two years. There were nine surgeons in the study total — four who had less than five years of experience and five surgeons who had five or more years of experience. Around 165 patients were included in the study.
The researchers found:
1. Less experienced surgeons fused an average of 1.2 levels more than the more experienced surgeons.
2. Patients in the less experienced surgeons' group reported more than twice as much estimated blood loss as the experienced group. Patients in the young surgeons' group reported 2,042 mL of estimated blood loss, compared to 1,013 mL for the experienced surgeons' group.
3. Surgical time was 458 minutes for the less experienced surgeons and 265 minutes for the more experienced surgeons.
4. Overall SRS-22 scores were significantly worse in the less experienced surgeons' group than the more experienced surgeons' group. The average score was 4.1 for the less experienced group, compared with 4.5 for the more experienced group.
5. Pain, self-image and function had significant differences between both groups. However, complication rates were relatively the same between the less and more experienced surgeons.
