Brief Summary

The process of bony fusion is a dynamic bone remodeling process and a variety of risk factors have been identified to contribute to pseudoarthrosis.Vitamin D deficiency has been reported to be associated with more pseudoarthrosis, prolonged time to fusion, and poorer spine function and quality of life after spinal fusion.However, as the review article presented, it lacks high-quality evidence to investigate the role of vitamin D supplements in spinal fusion. Therefore, this randomized controlled trial aimed to evaluate the effectiveness of oral vitamin D supplements on fusion outcomes in patients receiving elective lumbar spinal fusion.

Outcome Measures

Primary Outcomes (1)

  • fusion rate at postoperative 1 year

    Fusion status were assessed by radiography and computed tomography of the lumbar spine. Fusion was defined as the presence of bridging callus without radiolucent line, spinal range of motion between two fused vertebrae less than 5 degrees, and no implant loosening or failure on lumbar spine radiography.

    postoperative 1 year

Secondary Outcomes (5)

  • time to fusion

    from postoperative day 1 to postoperative 1 year

  • spine function at postoperative 3 months

    postoperative 3 months

  • spine function at postoperative 6 months

    postoperative 6 months

  • pain at postoperative 3 months

    postoperative 3 months

  • pain at postoperative 6 months

    postoperative 6 months
