Clinical Trial 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

Type	Measure	Description	Time frame	Safety issue
Primary	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	time to fusion	Time to fusion were assessed by radiography and computed tomography (CT) 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	from postoperative day 1 to postoperative 1 year
Secondary	spine function at postoperative 3 months	Spine function was evaluated using Oswestry Disability Index (ODI), which contains 10 patient-completed questions addressing spinal function. Each question is presented as 6-point Likert scales from 0 to 5 (0 = best outcome, 5 = worst outcome). The overall ODI score ranges from 0% to 100% and a lower score indicates better function.	postoperative 3 months
Secondary	spine function at postoperative 6 months	Spine function was evaluated using Oswestry Disability Index (ODI), which contains 10 patient-completed questions addressing spinal function. Each question is presented as 6-point Likert scales from 0 to 5 (0 = best outcome, 5 = worst outcome). The overall ODI score ranges from 0% to 100% and a lower score indicates better function.	postoperative 6 months
Secondary	pain at postoperative 3 months	Degree of pain was evaluated using visual analogue scale (VAS), which ranges from 0 to 10 (0 = least pain, 10 = worst pain).	postoperative 3 months
Secondary	pain at postoperative 6 months	Degree of pain was evaluated using visual analogue scale (VAS), which ranges from 0 to 10 (0 = least pain, 10 = worst pain).	postoperative 6 months
