About this study

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: postoperative 1 year

Secondary outcomes (5)
  1. 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

    Measured: from postoperative day 1 to postoperative 1 year

  2. 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.

    Measured: postoperative 3 months

  3. 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.

    Measured: postoperative 6 months

  4. 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).

    Measured: postoperative 3 months

  5. 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).

    Measured: postoperative 6 months

Questions about this trial

What is this clinical trial studying?

A study testing vitamin D3 and calcium in people with Vitamin D and Spinal Fusion, run by Show Chwan Memorial Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

fusion rate at postoperative 1 year (time frame: postoperative 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05023122, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2021.
