Clinical comparative study of 3-column fusion versus 2-column fusion for lumbar instability
[Objective] To compare the clinical results of 3-column fusion versus 2-column fusion on lumbar instability.[Method] Seventy-eight patients with lumbar instability underwent posterior lumbar fusion in the past seven years.Forty patients were divided into 3-column fusion group and 38 patients into 2-column fusion group.The efficacy of the two fusion methods was evaluated on operation period,blood loss,functional recovery,spinal fusion rate,complication rate,and the maintenance of the lumbar lordosis.The follow-up periods last at least 2 years.[Result] The 3-column fusion group had lower complication rate,and better maintenance of the lumbar lordosis.While the spinal fusion rate,operation period,blood loss,functional recovery had no significant difference between the 2 groups.[Conclusion] Both 2-column or 3-column fusion can get high fusion rate,improved functional recovery,but 3-column lumbar fusion patients had better maintenance of the lumbar lordosis and fewer complications.
