PurposeOrthosis after lumbar fusion surgery is common. However, the evidence for benefit remains to be determined, especially in tropical areas with heavy workers. To investigate postoperative orthosis and whether it affects pain improvement, quality of life, and fusion rate.MethodFrom May 2021 to May 2022, this single-center prospective randomized clinical trial enrolled 110 patients. We excluded 9 patients, and 101 people were analyzed finally. Corset group, in which participants used a corset for 3 months postoperatively; Non-corset group, in which participants didn't wear any orthosis. ODI and VAS scale were recorded before the surgery: 2 weeks, 1 month, 3 months, half a year, and 1 year postoperatively. The lumbar X-ray was done before the surgery, 6 months postoperatively. All complications in 1 year were recorded.ResultsSignificant decrease in VAS score in the non-corset group since post-operation day 5 (corset group 3.44 ± 1.77, non-corset group 3.36 ± 1.75, P = .0093) during admission, and also a decrease in admission duration (corset group 11.08 ± 2.39, non-corset group 9.55 ± 1.75, P = .0004) were found. There was a significantly better ODI score in the non-corset group since post-operation 1 month, while in the corset group until post-operation 3 months. Both groups had no significant difference in satisfaction, complication rates, and X-ray results, such as fusion, angular rotation, sagittal transition, and slip in the neutral position.ConclusionAfter the transpedicular screw fixation with posterolateral fusion surgery for degenerative spondylolisthesis, non-orthosis is a safe strategy. It can reduce the admission duration and has the trend for better functional outcomes.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
